my plot is created from a data file with
set palette defined ( ... )
plot 'datafile' u 1:2:3 with image
How do i add transparancy to the plot ?
set style fill transparent has no effect on an image plot
There is also no syntax in set palette defined to add tranparency
The only solution i found is using rgbalpha style.
But there a had to split the third data column into r g b values.
Is there an easier solution?
