Is it possible to reduce the alpha for markers in a simple plot?

Hi all,

I am having a simple plot like

plot(X,Y, 'MarkerFaceColor','#0072BD')

Is it possible to reduce the transparency of MarkerFaceColor to 0.5?

Thanks in advance

Plot function doesn't have support to tune transparency. You can use scatter to do that

scat = scatter(x,y,'MarkerFaceColor','b','MarkerEdgeColor','r'); 
scat.MarkerFaceAlpha = .5;
scat.MarkerEdgeAlpha = .5;

You can manipulate the color values, if you wish to use plot function.

hand = plot(X,Y,'r');
hand.LineWidth = 2;
hand.Color(4)=0.2; % this would act as your alpha value or transparency factor.

@ANKUR KUMAR why is the index 4? I never get indexing in plots :D

[ANKUR KUMAR]

First three indices are for RGB color, and the fourth index is the transparency.
