Hold plot for several different cases

Hi, I have created a GUI where a case is selected from a popup menu, points are calculated according to this case and a plot is drawn once a button "START" is pushed. I would now like to hold plots each time the button START is pushed, i.e. I want to be able to compare the plots between different cases.

This is what my function file looks like:

function [ ] = plot_calc(x, y, z, name, color, handles )
plot(handles.plot,x,y,'DisplayName',name,'Color',color);
box(handles.plot,'on');
grid(handles.plot,'on');
%hold(handles.plot,'all');
xlabel(handles.plot,'Axis(mm)','FontSize',10);
ylabel(handles.plot,'Deformation','FontSize',10);

Where do I have to insert the hold-command? Or what do I have to do to keep the graphs?

Thank you!!

Hi,

the simplest would be to add after the plot command:

plot(handles.plot,x,y,'DisplayName',name,'Color',color);
hold(handles.plot, 'on');

Thanks for the answer. Unfortunately, the plot is still overwritten once I hit the Start-Button. There might be another piece of code that disables holding in the rest of my script. What would be a typical command I would have to look for?

Thanks.

Interesting. Should be either a call to "hold" or someone setting the "NextPlot" property of handles.plot ('replace' instead of 'add').

Hi, at one point in the script, the command cla(...) cleared the axes. Since I didn't write the code myself, I missed it while looking through the script. Everything is now working. Thanks!

Jepp, forgot to add cla to the list above ;-). If everything works, you might mark the question as answered then ...
