# How to switch between plotting on two different axis in one gui function

I have a data set that includes 25 sets of time, position x, y,z forces, and torque. I am using a GUI to access all of the data and plot a portion of any two of the columns on a single plot that updates with a slider bar. I have gotten that to work great, however I now want to be able to have a second plot that will plot data similar to the first and update in the same slide bar. I am having trouble switching from one plot to the other and the data updates on the most recent plot. How can I switch between these two?

So I have tried this. But an error comes up that says "Invalid axes handle". I have some logic that determines which data is plotted and before each plot I have the line axes(handles.axes2);
for which plot I want to plot on, but if I try to plot to the same axes that was used last I get that error.
It will work once but then the second time it throws that error.
a simple pseudo code for this program is as follows
load data sets and put them in handles
dropdown menus for what data
% - radio buttton -
if button is 1
if certian drop down options are loaded
axes(handels.plot);
polarplot(data1(first section, data2)
hold on
polarplot(data1(2nd section, data2) (this is done to achive different colors)
hold on
Axes(handles.a_plot)
plot(data3, data4)
hold on
else
axes(handles.plot);
cla
axes(handels.a_plot);
cla
When I clear the button that is when it breaks and gives the error spoken above.

Hi,
Put the name of your axes in the first argument of your function plot. Example :
plot(handles.axes1,[0 1],[0 1])
plot(handles.axes2,[0 3],[0 1])

I have figured it out. The plot was made with cartesian so when I called for a polarplot the handles.axes1 was deleted to support the new one. So after plotting I assigned the handles.axes1 to the current gca and updated my handles. This is working great. Thanks
