How to increase marker size in scatter plot?

I tried to increase the marker size:

scatter(X,Y,'+','k', 'MarkerSize', 10);

How to increase the size (e.g. twice bigger '+')?

According to the scatter documentation, like this:

scatter(X,Y,20,'k','+')
            ^ this is the size

He asked about scatterplot, not scatter

[Igor Yashayaev]

Nope, this does not work, once you indicate a different marker, the size does not see it

[DGM]

X = randn(100,1);
Y = randn(100,1);
scatter(X,Y,10,'k','+')

scatter(X,Y,50,'k','+')

From the documentation:

The size controls the area of each marker in points squared

so the response may indeed not seem linear if you're thinking in terms of radius.

I retract my statement ... The trick is that you need to indicate much larger size than you would in plot(). I tried 10 before, and the markers remained small, but 15 showed some growth.

thanks so much
