Multiple plots in uiaxes in app designer

Hi

I am trying to use multiple UIAxes in in the same UIAxes in app designer. I have a main UIAxes with ticks and labels where I want to plot 16-channel signal. Each channel I want to plot in their own uiaxes, buth without ticks and labels and color. To do so I use this code:

for i = 1:length(app.channel_selected)
                app.axes_list(i) = uiaxes(app.RecordingsTab,'Position', app.UIAxes.Position);
                set(app.axes_list(i), 'PositionConstraint','innerposition');
                set(app.axes_list(i), 'XTick', []);
                set(app.axes_list(i), 'YTick', []);
                set(app.axes_list(i), 'Color', 'none');
end

But when the signal is plottet, it is plottet outside of the main UIAxes.

How can I alligne these multple UIAxes with the main UIAxes the signals will be shown whithin the main axes? I tried to use 'innerposition', it became better, but still not enough.

Thank you

I think 'Innerposition' should work, could you elaborate more about 'it became better, but still not enough'. What is the meaning of 'still not enough'?

[Anna Sergeeva]

I mean that the signals are still outside of the main plot. If I did not have the second line in the loop (set(app.axes_list(i), 'PositionConstraint','innerposition');) the plots with signals were even bigger than the main plot.

[Simon Chan]

I overlooked the 'innerposition' is used for 'PositionConstraint'.

Did you try to set the first and third values on 'InnerPosition' of the channel axis to be the same as the main axis?

ax1.InnerPosition(1) = ax.InnerPosition(1);

ax1.InnerPosition(3) = ax.InnerPosition(3);

where ax is the main axis

I tryied that. It did not help :-(

[Anna Sergeeva]

Now I add this line in the code

set(app.axes_list(i), 'InnerPosition', app.UIAxes.InnerPosition);

And it works now :-)

Thank you for helping me to reach there.

I would try using a different approach. Have you looked into stackedplot?

[Anna Sergeeva]

Thank you for your answer. I will take a look.

I have the same problem Matlab R2020b. The documentation is here but doesn't work. I have used: app.UIAxes2.PositionConstraint = 'innerposition' for my code but the result doesn't work :(

[Anna Sergeeva]

Try this

set(app.UIAxes2, 'InnerPosition', app.UIAxes1.InnerPosition);

It helped me :-)

Best

Many thanks Anna! Now it works! :)
