Hi,

I have not tried within apps, but the getDataTips function from File Exchange may help you to extract the data from the data tips.

It is not clear to me how you decide what values should go into what edit field, but I suppose that is the easier task.

Best wishes,

Harald

Hello Herald,

I have used function like you have mentioned but now I got this error:

Error using datacursormode

Invalid figure handle

Error in Test_tool/ButtonPushed (line 5052)

datacursormode(app.UIAxes2, 'on');

This is my aplication's small part:

You can see that I am using UIAxes on second tab. Also, There are 5 editfield but I want to fillout first 2 and last one. In the first two, I need only Y vlaue, which is selected near Y Axis (0.56 and 79.31) and In the last one I need only X value (5.1). for that I am using this code:

datacursormode(app.UIAxes2, 'on');
            dcm = datacursormode;
            % Get information about the selected data points
            info = getCursorInfo(dcm);
            % Extract Y values from the selected data points
            y1_value = info(3).Position(2);
            y2_value = info(2).Position(2);
            vmax_vlaue = info(1).Position(1);
            von1 = sprintf('%.0f', y1_value); % Format to one decimal place
            bis1 = sprintf('%.0f', y2_value);
            Vmax_1 = sprintf('%.1f', vmax_vlaue);
            app.Von1EditField_ACX.Value = str2double(von1);
            app.Bis1EditField_ACX.Value = str2double(bis1);
            app.Vmax_1EditField_DVX.Value = str2double(Vmax_1);

Hi,

I have checked it and It is same name as in component browser. So, I think that is not a problem.

with regards

Hi,

unfortunately, this is the only suggestion I can make from the code and error provided.

To further investigate for you, I would need a reproducible example. You would not have to share the full app, but enough to run the app and encounter the error message.

Best wishes,

Harald
