@aaron,

I think I must not understand you. I think you are saying that the above code puts the same plot on two different axis. The above code would not do that though.

Please contact tech support, http://www.mathworks.com/support and they can help you better.

It seems the same plot ends up on both axes. I tried to implement a plot axes pushbutton for both axes. This is what I have for code under the plot axes pushbutton.
function PlotAxes1_pushbutton_Callback(hObject, eventdata, handles)
% hObject handle to PlotAxes1_pushbutton (see GCBO)
% eventdata reserved – to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
fileName = handles.fileName;
axes(handles.axes1)
[x,y] = readExcelcolumns(fileName, xcolNum, ycolNum)
hold all
plot (handles.axes1, x,y)
axis ([320 400 0.760 0.900])
guidata(hObject, handles)

This plots on both axes. When I try the next function plot axes2 pushbutton it does not seem to plot the data into axes2. The axes1 data plots in both axes1 and axes2

I am not sure if this is the right approach.

@Aaron,

What have you tried. Where is the stumbling point? Adding a second axis, are both plots going to the same axis? You should capture the handles from each axes and use them as inputs into the plotting functions.

If I added a second axes on the GUI, how would I implement the code to plot two different graphs on the same GUI? Both plots are coming from the data that is read into Matlab from excel, just like the tutorial shows. I just want to be able to produce two plots in one GUI.

@Ram,

XLSREAD can do this.

Hi Doug,
I am trying to open a Excel file which has multiple sheets. I can use winopen command to open any file in MATLAB. But how could open a specific work sheet?

If anyone could answer this, it will be very helpful. I am looking for a quick win.

Thanks!

Thanks for your reply.

i want to use same filename. and i want to write one figure and under that some numeric data. If i write figure first using activx and then use xlswrite to write numeric data then figure is gone and only numeric data remains and vice versa.

@ros,

Are you always using the same filename for Excel? That is why it is overwriting maybe. If you are using the same file name, what do you want to happen?

Hi,
I am trying to export a ‘figure’ and some Numerical data into excel. I first save’figure’ using ‘activx’ and then I write numerical data using ‘xlswrite’. but everytime matlab overwrites the existing data in excel. Is it not possible to write both figure and data with just matlab commands(without installing any other tools)? Please help.
thanks.
