How to export XaxisTick Labels which are cell arrays to figure or powerpoint in app designer?

Please refer to the attached figure. If i keep the XaxisTicklabels as 1,2,3 and so on, it can be exported to PPT or figure with the help of h = copyUIAxes(app.UIAxes,axh).

But if the XaxisTickLabels are as in attached image, it displays the following error:

"Value must be a vector of type single or double whose values increase"

How to proceed with this?

[Adam Danz]

I have a feeling you're not setting the XTickLabel properly. Are you setting it from within the App Designer UI (screenshot below) or are you setting it programmatically from within the code? It's also good to know the Matlab version you're using.

As you can see in the 2nd image below, copyUIAxes() correctly copied the bar chart without an error.

Hello Adam,

I am using Matlab2019b version.

I am setting XtickLabels programmatically. And their data type class is cell array.

and in my code - copyUIAxes(app.UIAxes,axh)

axh = axes;

when i debug the code and check the value of XAxisTickLabels. It gives XAxisTickLabels = 9 * 1 cell array

{'straight' }

{'bend' }

{'junction' }

{'crossing' }

{'roundabout' }

{'other' }

{'unknown' }

{'car park' }

{'property exit'}

Even if I change data type of XTickLabels, how should i inculcate that under axh, so that it starts working.

Thanks

Rohit

Please provide the entire copy-pasted error message (all of it).

It would also be helpful to see the section of code where you change the labels.

Hi Adam,

Error:

Section of the code where I changed labels:

   % Ticks with valid codes and labels
%     labelName = strcat('app.data.',plotLabelName);
%     labelName = labelName{1};  % Extract the label's name out of cell
    xtickValues = makeUnique(plotData);
    xtickLabels = cell(size(xtickValues));
    for ii = 1:numel(xtickValues)
        xtickLabels{ii} = mapCodes2labels_eng(xtickValues(ii));
    end
    % Convert numerical data to categorical
    categoricalPlotData = categorical(plotData, xtickValues, xtickLabels);
    h = histogram(app.UIAxes, categoricalPlotData);

Section of Code where I want to copy UI Axes

% Convert plot to  image format
 fNew = figure();
 set(fNew, 'Visible', 'off');
 axh = axes;   
 h = copyUIAxes(app.UIAxes,fNew);------ "% I am getting error at this line"
 set(gcf,'color','w')
% Add Plot slide
% figH = figure();
exportToPPTX('addpicture',figure,'Visible', 'on','Position',[2.5 1 5 4]);
exportToPPTX('save',[app.foldername '\PlotCreator\' templatePPT]);
exportToPPTX('close',[app.foldername '\PlotCreator\' templatePPT])

I see... I won't be able to troubleshoot this without running it. Could you attach the app and instructions how to recreate the error?

Update: Before you do that, I noticed in your error message,

Error in copyUIAxes (line 148)

however, the current version of copyUIAxes() shows that line of code on line 153, not 148. So, either something was altered in your file or you're not using the most recent version of copyUIAxes. So, first download the updated version and if the error continues, provide the new copy-pasted error message and attach the app.

I have updated the copyUIAxesVersion still the error continues:

I cannot attach the app here..

[Adam Danz]

Update, with some guessing work (that was necessary since I wasn't provided an example), I've been able to recreate the problem and am working on a solution.

The problem is that your historgram data are categorical the categorical properties aren't copied to the new axes.

I'll update you when a solution is ready.

@Rohit Deshmukh, please download and start using the new version of copyUIAxes() (verson 1.2.0, as of 19-Mar, 2020).

I've updated it to work with categorical histograms. Please let me know if you have any further problems.

Thank you Adams ! I am having some similar problems , If I just contain the CopyUIAxes into my app designer code and compiler, will it work ? I also need to save Histograms

here is my question

Hello Adam. Thanks for helpful function. However, I am getting the following error:

Error using matlab.graphics.axis.Axes/set

Value must be a vector of type single or double whose values increase.

Error in copyUIAxes (line 185)

set(h.axes, uiaxGoodParams)

I am plotting a horizontal bar chart with categorical values. I see in the thread, that this has caused some problems before?

Im using the latests version 1.2.0.1 and running R2020a.

[Adam Danz]

Hi Emil, Matlab's r2020a release includes functions exportgraphics or copygraphics which can be used in place of copyUIAxes. I'll eventually update copyUIAxes to urge people to use these new functions starting in r2020a.

Please let me know if you have any problems using the new Matlab functions.

[Emil Alexandersen]

Hi Adam. I have just found the exportgraphics fucntion and it works!. Many thanks though!

Wish you a lovely evening-

[Adam Danz]

Thanks, Emil. I would be interested in hearing of any shortcoming you may find with that function.

[Emil Alexandersen]

Yes, will keep you updated if I find any problems. :-)
