[gradsusr] scatter plot to print values of proportional size in the scatter!

Hi, Muthu —
What you ask would require a fair amount of script code that would pass through every grid point, calculate the position and size, and draw each value individually. A simpler route might be to use the optional 3rd argument to colorize the scattered dots. http://cola.gmu.edu/grads/gadoc/scatterplot.html

If you use const(), maskout(), and ‘set digsiz’ you should be able to control the size of the scatter marks for a range of values.

Hi grads experts,

A) I have used simple scatter plots of 2 vars, as they are very simple
to do by setting gxout  to scatter.

Have u tried this one?
Suppose I have a third variable (which is, say, physically related to the two variables), and instead of plotting a simple point in the above example A, I want to plot/write_out the actual value of the third variable, the font size of which is  proportional to the numeric value of the third variable. U get it?

Any help will be appreciated. Jennifer (Adams), I know you may
have some tricks in your sleeve! :-)

Thanks a lot.
