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))
