Refresh plot using switch case with dropdown menu in App designer

Hi everyone,

I have designed an app, which has a drop down menu to select what will be ploted and it works fine. I want to improve the app, so that when I change the value of X or Y lim in numeric fields it will be automatically refreshed. For now, after changing the value in the numeric field I have to select again the same plot in my dropdown menu, to see the plot with the new limits for both axes.

For the limits on the X and Y Axes I am using following commands:

xlim(app.UIAxes, [app.Xmin app.Xmax])
ylim(app.UIAxes, [app.Ymin app.Ymax])

for this app I should avoid using the timer function. Is there another way to refresh the Axes and see the plot with the new limit?

Thank you!

 plot(x,y) 
ax = gca % get the axes  handle of current plot 
delete(ax);% delete the axes handle

Hope this works

Hello VBBV

I appreciate your help! I've tried and it didn't work. After trying

ax = gca % get the axes  handle of current plot 
delete(ax);% delete the axes handle

It didn't work. It opens a new blank figure. I tried using the UIAxes properties, but I couldn't control the axis as well.

The goal is changing the axis limits values without having to plot the figure again.

Do you have an idea?

ax = axes
plot(ax,x,y) 
axes('Position',ax.Position,'XLim', [Xmin Xmax],'YLim',[Ymin Ymax]);% assign the new axes range
