Hello,

I have built an App that Plots data. Now I have a button, that should set the x-Axis-Limits to default (like zooming out of my Plot). In addition to that I would like to show the actual x-axis-limits in Edit-Fields:

In my code I have implemented this by using "Inf" as limits:

app.axes.XLim = [-Inf, Inf];

Is there now a possibility to get the actual real limits, that are used in the Plot, instead of "-Inf" and "Inf"? I want to show the real Numbers in the X-min and X-max edit fields.

Best regards

Nico

[Edited to include the correction noted in the comment]

From what I can tell, no, you can't get that information directly.

But it should match the min and max values of the plotted data, so a work-around might be evaluate the axes children and find the maximum values.

Alternately, you could change the Limit Mode to "auto" (app.axes.XLimMode = "auto") and the Limit Method to "tight" (app.axes.XLimitMethod = "tight"). That should provide the same visual result as setting app.axes.XLim = [-Inf, Inf], but allows you to access the automatically calculated value with something like x = app.axes.XLim
