I am working in AppDesigner and I create an uiaxes where i simply plot some lines. When the mouse is near the plotted line i get a bunch of errormessages in the command window:

Hi,
This issue occurs when we try to plot mixed datatypes in UIAxes in R2019a. This has been fixed in R2019b.
Meanwhile for R2019a, you can try a workaround for disabling the errors/warnings.
plot(....) % Your plot command
ax = gca;
disableDefaultInteractivity(ax)

I had a similar issue. I was working with uint's. I found if I plotted my data as double, I no longer received the constant warning.
e.g.
plot(app.UIAxes, xData, double(yData))
