[Scilab-users] grayplot

[Rafael Guerra]

Hi Samuel,

Scilab-6  'scatter' plot function seems indeed quite adequate for these data.
Would it be possible to produce such scatter plots with dots color coded (as attached) in Scilab 5?

Thanks and regards,
Rafael

scatter() is also dedicated to this kind of sparse plotting:
