Rotate stacked plot Labels to have them vertical - App Designer

Hi,

i am using stacked plots in App Designer to visulize some data and i would love to rotate the labels on the left side of these plots, having them in vertical direction.

Does Anybody know if this is possible at all with stacked plots?

Thank you very much!

For normal plots ‘ytickangle’ can be used in order to rotate the y-axis label.

But in case of stacked plots y-axis labels are treated as ‘DisplayLabels’ and their orientation cannot be changed.

[Andrea Quintarelli]

that's a shame. Thank you very much anyway for clarifying!

[Bruce Vernham]

If that is the case than this feature is completely usless for displaying data and not worth the time and effort to implement the code!

True, only for that particular reason I am unable to use it

You can get the axis handles in stackedplot using the undocumented NodeChildren property. Then rotate and center the labels.

rng('default')
h = stackedplot(rand(100,4));
drawnow
ax = findobj(h.NodeChildren, 'Type','Axes');
set([ax.YLabel],'Rotation',90,'HorizontalAlignment', 'Center', 'VerticalAlignment', 'Bottom')

Adam, I had the same problem. The code helps thanks

[Seth West]

This doesn't seem to work any more. (R2022b)

Unrecognized method, property, or field 'YLabel' for class 'matlab.graphics.GraphicsPlaceholder'.

[Adam Danz]

The stackedplot needs to render before calling findobj(). You can put a drawnow after stackedplot() to fix that.

For some reason this is not working for me on MATLAB 2023a running on Windows 11. I also want to change the interpreter for the Y axis to 'tex'. I don't know if it changes anything but I'm using a LiveScript with Output on Right.

This is my code:

figure;
opts.str = 'AE monitoring results 2022-06-14 16:42:40 [120 kN]';
opts.s = stackedplot(MainTT,RateTT,bValueTT,opts.vars,"LegendVisible","off",...
    "GridVisible","on",'Title',opts.str);
drawnow
opts.c = parula(numel(opts.s.LineProperties));
opts.ax = findobj(opts.s.NodeChildren,'Type','Axes');
set([opts.ax.YLabel],'Rotation',90,'HorizontalAlignment', ...
    'Center', 'VerticalAlignment', 'Bottom', 'Interpreter','tex');

for ii=1:numel(opts.s.LineProperties)
    opts.s.LineProperties(ii).MarkerEdgeColor = "k";
    opts.s.LineProperties(ii).MarkerFaceColor = opts.c(ii,:);
    opts.ax(ii).XAxis.Exponent = 0; %turn off scientific notation on axis
end

% Adjust individual graphs
%  Make every graph from 2 to 'n' scatter 
for ii = 2:numel(opts.s.LineProperties)
    opts.s.LineProperties(ii).PlotType = "scatter";
    opts.s.LineProperties(ii).MarkerFaceColor = opts.c(ii,:);
end

% AccumRate
opts.s.AxesProperties(1).LegendLabels = {'cum AE'};

% Rate
opts.s.AxesProperties(2).LegendLabels = {'AE/sec'};

%  Frequency
opts.s.AxesProperties(3).YLimits = [0 1000];
opts.s.AxesProperties(3).LegendLabels = {'f (kHz)'};

% Amplitude
opts.s.AxesProperties(4).YLimits = [0 140];
opts.s.AxesProperties(4).LegendLabels = {'A (dB)'};

%  beta_t
opts.s.LineProperties(end-1).PlotType = 'plot';
opts.s.LineProperties(end-1).LineStyle = '--';
opts.s.LineProperties(end-1).Color = 'k';
opts.s.LineProperties(end-1).Marker = 'o';
opts.s.LineProperties(end-1).MarkerFaceColor = opts.c(end-1,:);
opts.s.LineProperties(end-1).MarkerEdgeColor = 'k';
opts.s.AxesProperties(end-1).LegendLabels = {'\Beta_t'};

%  b-Value
opts.s.LineProperties(end).PlotType = 'plot';
opts.s.LineProperties(end).LineStyle = '--';
opts.s.LineProperties(end).Color = 'k';
opts.s.LineProperties(end).Marker = 'o';
opts.s.LineProperties(end).MarkerFaceColor = opts.c(end,:);
opts.s.LineProperties(end).MarkerEdgeColor = 'k';
opts.s.AxesProperties(end).YLimits = [0.5 2];
opts.s.AxesProperties(end).LegendLabels = {'b-value'};

clear opts ii

And this is my output

Also the Interpreter seems to be changing just for the title (which is not what I want).

When I copy and run your code it works as intendend. My guess is that some of my other property settings is interfering with the set function, but I can't grasp what it is.

@Pedro when using undocumented features there's no guarantee that they will always work. Figures generated in live scripts behave differently and don't support these undocumented features.

I recommend writing to tech support to request an interpreter property in stackedplot as well as having access to the axes label handles. Go to Contact Support > Report a Bug > Select Technical Support & Product help, bugs, suggestions.
