Scatter plot with variable symbol size - it's not linear
显示 更早的评论
I'm trying to use the feature in the scatter plot where the symbol size is proportional to a variable and it seems that the scaling of the symbol size is not linear.
Here is some test code and the resulting plot:
x = 1:100;
y = ones( size(x) );
scatter( x, y, 100*x, '|' );
xlim( [0 101] );
ylim( [0 2] );
Is this the expected behaviour? I need the symbol size to vary linearly with the variable.

According to the documentation for scatter, the size in "points squared" units, try this
x = 1:100;
y = ones( size(x) );
scatter( x, y, x.^2,'|' );
xlim( [0 101] );
ylim( [0 2] );
