Updating data in a plot in UIAxes

Question

0 个投票

Hi,

As part of my program, I am developing an app.

The app requires me to present some results as plots (6 plots) that must be updated every two seconds.

Using 'drawnow' causes the processing to be slow.

I need to use the command 'refreshdata', however, it does not appear to work the same way as the code I developed as a .m file.

It would be greatly appreciated if anyone could provide me with some guidance on this subject.

Hi,

Thank you for your answer.

I tried several times and none of the method like linkdata and refreshdata works in appdesigner.

It works in my mfile but not in appdesigner.

In an app, for this situation, I prefer updating the XData and YData of the line rather than replotting. See this answer:
