how to count the number of points in a scatter plot

Hi,

I made a scatter plot using two columns where there were a few NaNs. Those rows were automatically get eliminated when I use the "scatter" command. Now I want to see how many data points on the scatter plot. Please help me with this. Thanks

How about using isnan() on the x and y to find out which are not nans?

numberOfGoodPoints = sum(~isnan(x) & ~isnan(y))
