How can I scatterplot by group by the sign of the variable?
显示 更早的评论
Hello!
I have data for two variables:
I wish to scatterplot the viarables such that when the variables have the same sign, lets say, both positive, the plot is filled. If they are not identical, they are not filled.
It will look something as this
Thanks :-)

If you have the statistics and machine learning toolbox,
g = sign(var1)==sign(var2);
gscatter(x,y,g)
If you do not have access to gscatter,
g = sign(var1)==sign(var2);
scatter(x(g),y(g));
hold on
scatter(x(~g),y(~g));
In both cases, x, y, and g must have the same number of elements.
