Editing: 'off' topixels then converts the dummy object’s position from axes data units to pixel units. I have already considered to simply "normalize" those positions myself (e.g. If you do not specify the DeleteFcn property, then MATLAB executes a default deletion function. example. How can I do that? If there is no figure, MATLAB ® creates a figure and places the layout into it. I have tried to convert the units, and to use other units like pixels or centimeters but I could not get it to work (but maybe I am doing something wrong). I have been reading through Yair Altman's undocumented matlab site on this topic as well as checked other answers here and in other forums but I cannot quite work out how to adjust these suggestions for my particular problem. To display an annotation within a specific figure, uipanel, or uitab, use the container input argument. pos = hgconvertunits(hFig, get(Axes, 'position'), get(Axes, 'units'), 'Normalized', hFig); % ^^^^ We could have used some other Y data value for this, % Ensure that the annotation fits in the window by enlarging, % YLim may have changed, so recalculate y, % Convert axes data position to figure normalized position, % uses %matlabroot%/toolbox/matlab/scribe/@scribe/@scribepin/topixels.m, % Ensure that the annotation is within the axes bounds, then display it, % Annotation position is outside axes boundaries, so bail out without drawing, % Create a text-arrow annotation with the requested string at the requested position, % Example for setting annotation properties, % Pin the annotation object to the required axes position, % Note: some of the following could fail in certain cases - never mind, %Setting initial annotation position within the figure bounds, %matlabroottoolboxmatlabscribe@scribe@scribeobject1DcreatePinContextMenu.mfunction localPinObject. PixelBounds: [0 0 0 0] I also tried it for textboxes, which are located on the doublearrows. In fact, they have more undocumented properties than documented ones. localPinObject(har);%matlabroottoolboxmatlabscribe@scribe@scribeobject1DcreatePinContextMenu.mfunction localPinObject TailLineStyle: '-' TailLineWidth: 0.5 Previous versions of MATLAB ® allow annotations to extend into (or out of) the boundaries. tAnnotation.pinAtAffordance(1); The following Matlab project contains the source code and Matlab examples used for annotation pinned to axes. This is based on a transparent hidden axes that spans the entire figure’s content area, on which the annotations are being drawn (also called the scribe layer). 0 Comments. Basic annotation ¶. For this we use %matlabroot%/toolbox/matlab/scribe/@scribe/@scribepin/topixels.m. The undocumented ability to pin annotations to a specific axes location is explained here: https://undocumentedmatlab.com/blog/pinning-annotations-to-graphs Note: This is an undocumented feature, but it was directly referenced by an official Mathworks solution , so it can't be too bad :-) 90 s/180 s = 0.5 --> x-position in normalized coordinates). Modify Figures in Live Scripts. NormY: [0.5 0.7] - In that imported data matrix, which has a new data every 3 minutes, I impose a condition. Add a circle to the chart to highlight where f(x) and g(x) are equal. p.s. I needed to be able to create annotations to plots that would be pinned to the axes … I'm trying to implement a modified version of datetick2 from the MATLAB FEX. I really hope that a complete refactoring of scribe and the related uimodes will be one of the benefits that we will see in HG2. the x-axis. For this reason, annotation requires figure position – in fact, the annotation has no information about the axes beneath it. Is there a such command in Matlab? % uses %matlabroot%/toolbox/matlab/scribe/@scribe/@scribepin/topixels.m FaceColorProperty: 'HeadColor' These include arrow, doublearrow, textarrow, and ellipse. ... Find the treasures in MATLAB Central and … For example, if the left side is active, then the YLim property of the Axes object contains the limits for the left y-axis.However, if the right side is active, then the YLim property contains the limits for the right y-axis. I have found that I almost always want to specify my annotations in data space (i.e., based on the values of data displayed in an axes). Instead, they clip at the boundaries. XLimInclude: 'on' % YLim may have changed, so recalculate y Previous versions of MATLAB ® allow annotations to extend into (or out of) the boundaries. A Matlab text-arrow annotation (unpinned). If you specify this property as a categorical array, MATLAB ® uses the values in the array, not the categories. I understand you cannot set as a container the axes component so thought I could just get the x,y, coordinates of the axes. Another problem is to pin the annotation to the axes data. HeadRosePQ: 2 To add text to multiple points, specify x and y as vectors with equal length. (For example, when you need many labels on a figure). The uses of the basic text() will place text at an arbitrary position on the Axes. Find the treasures in MATLAB Central and discover how the community can help you! In fact, they are located in a separate axes layer. No problem, that's done. The following Matlab project contains the source code and Matlab examples used for annotation pinned to axes. axis off; Is this what you are looking for? I have already considered to simply "normalize" those positions myself (e.g. HeadColorMode: 'auto' Srect: [2x1 line] set (xlim = (-1, 5), ylim = (-3, 5)) This is definitely somewhere else on this website and in the matlab documentation. The only difference in use with the annotation function is that you can provide the axes handle. Learn more about annotation, text, figure, plot, text box, line, arrow, text arrow Learn more about pin Try to recreate my example on a new empty figure and then try to see what is different in your existing code/figure. Try playing with the relevant properties. HeadFaceColor: [0 0 0] You can use the attached function named "axxy2figxy.m" to transform coordinates from data (axes) space to figure space. Modifying the Text Arrow from the Context Menu Control the label for the new data series by setting the DisplayName property as a name-value pair during creation. % Prepare the annotation's Y position NormX: [0.2 0.4] I am looking for a programmatic solution, not interactive. Specify the axes as the first input argument. annotation; arrow figure line plot text arrow text box text; I would like to add vertical lines (or arrows) and text-labels below the x-axis at particular x-axis-values in my plots. This places a text box with horizontal offset of 50% of the Figure's width, and vertical offset of 20% of the Figure's height. So I’ll spare you the gruesome details and skip right to the chase. HeadEdgeColor: [0 0 0] hThis.Pin(2).DataPosition = [X2 Y2 Z2]; (You don't need the handles, … Some annotations created with the ANNOTATION function are positioned relative to the figure coordinate space rather that the axes coordinate space. It is using undocumented/unsupported internal code after all…. annotation; axes MATLAB Hello, I am trying to add an annotation (textbox) to a plot that is on an axes component (Im using GUIDE). PinExists: [0 0] hThis.Pin(1).updateTarget; Otherwise, the annotation function will shout. I have been using this approach, too. MoveMode: 'mouseover' drawnow; Hi Yair, Return the Ellipse object as an output argument from the annotation function. hThis = handle(har); Vote. Notice that all this relies on pure Matlab code (i.e., no mention of the dreaded J-word…). ANNOTATEAXES: Annotation object in axes data coordinate version 1.1.0.0 (10 KB) by Kesh Ikuma ANNOTATEAXES places a built-in annotation object and tie it to an axes StoredPosition: [] yLim = get(hAxes,'YLim'); HeadLineStyle: '-' EdgeColorProperty: 'Color' If you add or delete a data series from the axes, the legend updates accordingly. hAnnotation = handle([]); This is a snapshot of my code that creates the figure: In this example, T is a 41x1 double (listing values from -0.8 to 0.2), F is a 1025x1 double (listing values from 0 to 1000), and P(:,:,3) is a 1025x41 double; x_RTO = -0.4675; x_LHS = -0.5919; x_LTO = 0.1353. character to plot the arrows. I did notice one thing while using the code. If you specify the type as 'line', 'arrow', 'doublearrow', or 'textarrow', then the second input is the starting and ending x positions of the annotation. Toggle Main Navigation. The obvious first place to start debugging this issue is to go to the annotation handle’s context-menu (accessible via the UIContextMenu property), drill down to the “Pin” menu item and take a look at its callback. PropertyListeners: [8x1 handle.listener] To add text to one point, specify x and y as scalars. The third input is the starting and ending y positions of the annotation. Learn more about pin . ShapeType: 'textarrow' Call the tiledlayout function to create a 2-by-1 tiled chart layout. Call the tiledlayout function to create a 2-by-1 tiled chart layout. y = yLim(1) + 0*sum(yLim) + [0.1,0]*diff(ylim); % TODO: handle reverse, log Y-axes If you’d like me to investigate this specific issue for you, email me. To display an annotation within a specific figure, uipanel, or uitab, use the container input argument. % Example for setting annotation properties I believe this is due to the complex implementation, having quite a few checks and re-calculations (e.g., back and forth between coordinate systems and units). Selected: 'off' yyaxis (ax, ___) specifies the active side for the axes ax instead of the current axes. https://www.mathworks.com/matlabcentral/answers/247004-how-to-pin-annotations-or-text-to-a-graph-below-the-x-axis#answer_194895, https://www.mathworks.com/matlabcentral/answers/247004-how-to-pin-annotations-or-text-to-a-graph-below-the-x-axis#answer_299425. If axes exist in the specified position, then this command makes the axes the current axes. Use single quotes around 'left' and 'right'. I have been reading through Yair Altman's undocumented matlab site on this topic as well as checked other answers here and in other forums but I cannot quite work out how to adjust these suggestions for my particular problem. I had different values for x(1) and x(2). The first input to the function specifies the type of annotation you want to create. At the bottom end of those lines/arrows I would like to add labels ('LHS', 'RTO', 'RHS', 'RTO'; as shown in graph). Each interval in the X axis corresponds to new data. However, this way I cannot add lines/arrows with the labels and when resizing the image the labels are moving in y-direction (they seem to have a relative position rather than being pinned to an absolute value in the graph?). Masochistic readers may find many hours of pleasure sifting through the scribe code functionality for interesting nuggets such as the one above. I can't manage to get axes similar to the ones in this figure: I know I can remove the top and right lines like in this question, but I don't know how to get the arrows on the edges. You can see this using my uiinspect or getundoc utilities. ah1=subplot (2,1,1); annotation_pinned ('textarrow', [0.6,0.7], [0.3,0.5],'String','simple text','Interpreter','Latex') ah2=subplot (2,1,2); annotation_pinned ('arrow', [0.1,0.2], [0.5,0.1],'axes',ah1); The first step is to ensure that the initial annotation position is within the figure bounds. VerticalAlignmentMode: 'auto' In fact, anything having to do with the scribe layer is relatively slow. Through the handle returned by annotation we can customize the annotation’s appearance (for example, line width/style or text font properties). Estoy realizando un programa en el que genera bloques y flechas como annotation.... Cuando uso annotation las anotaicones se posicionan sobre el plot, pero no se anclan sobre él, por lo tanto al poner zoom o pan , se pierden por asi decirlo. Afsize: 6 CLimInclude: 'on' yLim = get(hAxes,'YLim'); annotation('line',x,y) creates a line annotation object that extends from the point defined by x(1),y(1) to the point defined by x(2),y(2), specified in normalized figure units. pos = pos(1:2)+pos(3:4)/2;%Setting initial annotation position within the figure bounds So if we store the axes handles for each tile then we can plot new changes to existing tile by shifting to that axes handle using axes function. Then display grid lines in the bottom plot by passing ax2 to the grid function. hFig = ancestor(hAxes,'figure'); Your code for pinning annotations to axis worked fine for doublearrows. Feel free to investigate and if you find out anything useful, come back here and place a comment for the benefit of others. 90 s/180 s = 0.5 --> x-position in normalized coordinates). Oh well, it’s better than nothing, I guess. hThis.Pin(1).DataPosition = [X1 Y1 Z1]; Often, we are interested in an annotation on a plot axes that does NOT span the... Debugging the problem. Note that it is ok to move the annotation outside the figure bounds later on (via panning/zooming) – it is only the initial annotation creation that must be within the figure bounds (i.e., between 0.0-1.0 in normalized X and Y units): % Prepare the annotation's X position ALimInclude: 'on' try Call the nexttile function to create the axes objects ax1 and ax2.Plot data into each of the axes. This in turn enabled me to take the essence of the pinning code and implement it in my stand-alone application code. Call the nexttile function to create the axes objects ax1 and ax2. Learn more about annotation, subplot, southeast, text box in plot, print value in subplot MATLAB FaceColorDescription: 'Head Color' We can indeed pin the annotation to the graph, but this requires delicate manual interaction (click the Edit Plot toolbar icon, then right-click the relevant annotation end-point, then select “Pin to Axes” from context menu). For example, this code creates a surface plot and a scatter plot, and then calls the alpha function to vary the transparency along the x -dimension. MATLAB executes the DeleteFcn callback before destroying the properties of the object. To create a circle, use the 'ellipse' option for the annotation type. A context-menu is only assigned to the annotation after the Edit Plot toolbar button and then the annotation object are clicked. hAnnotation.pinAtAffordance(1); If the current figure contains an existing axes or layout, MATLAB replaces it with a new layout. Hi @Yair Altman annotationX = figNormPos([1,1]); The axes function accepts property name/property value pairs, structure arrays, and cell arrays as input arguments (see the set and get commands for examples of … PinContextMenu: [2x1 uimenu] Show Hide all comments. tAnnotation.Pin(1).DataPosition = [timeOUTPlot(index1:index1), 10, 0]; What about pinning annotation shapes such as ellipses and rectangles? My hunch is that either you have a bug in your code, or perhaps your figure window has some element which causes the annotation scribe layer to behave differently. The annotations may appear to be connected to the plot axes, but this is merely a visual illusion. Here is the list for a simple text-arrow annotation, such as the one that we used above: >> getundoc(hAnnotation) y = yLim(1) + 0*sum(yLim) + [0.1,0]*diff(ylim); % TODO: handle reverse, log Y axes I have noticed that annotations in Matlab are considerably slower than the seemingly similar text objects. This does, however, not work, since 0 and 1 refer to points in the whole figure (the window in which the plot appears) and not to the area of the plot itself. Change the axes font size and x-axis color for … hAnnotation = handle(annotation('textarrow', annotationX, annotationY, ... A common use case of text is to annotate some feature of the plot, and the annotate() method provides helper functionality to make annotations easy. A lot of things broke in R2014b due to the replacement of the graphics engine in this release (HG2). Unfortunately, the annotation handle does not provide a documented way to do this programmatically. Can we do similar with textbox annotation objects? That positioning is done before the box is trimmed to the text, which leaves the text floating pretty far from the desired location. Accelerating the pace of engineering and science. Call the nexttile function to create the axes objects ax1 and ax2.Plot data into each axes. @ 2014b this dose not works. To display different text at each location, use a cell array. Unable to complete the action because of changes made to the page. I needed to be able to create annotations to plots that would be pinned to the axes like the text function. Pin: [0x1 double] tiledlayout(m,n) creates a tiled chart layout for displaying multiple plots in the current figure.The layout has a fixed m-by-n tile arrangement that can display up to m*n plots. Or a hexadecimal color code then try to see what is different in your code/figure. Or rotated 3D coordinates, you can display a tiling of plots using the code many.
