回答： Edite Figueiras 2018-12-18

I am ploting a figure using 'imshow' and I am ploting there several x,y points using the marker 'o'. Something like this:

imshow(myfigure,[], 'Parent',app.XYmaxProjection)

plot(app.XYmaxProjection, xcoordinates,ycoordinates,'ro', 'MarkerFaceColor', 'none', 'MarkerSize',10)

For some reason the MarkerFaceColor is always white. Is there a way to change this?

Thank you!

Hi,

I am assuming you saw this behaviour in R2018a which I think is an existing bug. Try the same in 18b and it should work fine.

I tried the following code (similar to your requirement) and was able to reproduce it in 18a but not in 18b. I have attached both the 18a and 18b outputs for your reference.

            x = rand(1,5);
            y = rand(1,5);
            h = plot(app.UIAxes,x,y,'ro');
            set(h,'MarkerFaceColor','none');
            set(app.UIAxes,'Color',[0 0 0]);
