Warning message: Erase mode property no longer supported!!

Hello,

I get the following warning message:

Warning: The EraseMode property is no longer supported and will error in a future release.

The corresponding code lines are :

KeSTART = 0;

KeSTEP = 0.025;

KeSTOP = 2;

AXDEF = [KeSTART KeSTOP 0 1];

colordef white;

f1 = figure;

p = plot(AXDEF(1)-1,AXDEF(3)-1,'k.');

drawnow;

set(p,'Erasemode','none','MarkerSize',1);

axis(AXDEF);

grid off;

hold on;

I found the following link: https://www.mathworks.com/help/matlab/graphics_transition/how-do-i-replace-the-erasemode-property.html.

It is stated that it can be replaced by animatedline, but I don't know how to replace it in the line of code.

Could you help with modifying the above code?

Lale - you may need to show more of your code so that we can get a better idea of what comes next. Why (in the above) were you using EraseMode?

Simply omit the 'Erasemode','none' in your code and do not delete the created line afterwards.

First of all thanks a lot for the kind reply. Before submitting this question, I tried that option. The warning message disappeared but unfortunately it didn't plot anything.

But this is not a problem of the EraseMode, but of:

axis(AXDEF)

The dot is drawn at [AXDEF(1)-1,AXDEF(3)-1], or [-1, -1] Then you move the visible area to [KeSTART KeSTOP 0 1], which is [0 2 0 1]. Having a width of 0 is strange, but most of all the point [-1, -1] is outside the visible area.

In older Matlab version the EraseMode took a role here, because the drawn dot was not removed from the view. But this is a dirty way of programming. Better define the limits of the diagram such, that you can see the data.

Thank you so much.
