#11 Overflow error using monaghanlattanzio and colourmap
I'm doing some colourmaps with rgb palettes, using functions, i could some some graphs but later the program started to throw overflow errors.
My script is
set sample grid 400x400 interpolate monaghanlattanzio
set size 8 square
set colourmap rgb(3*c1-1):(sin(c1*pi)):(1-(2*c1-0.84))
set yrange [7:50]
set xrange [15:33]
plot '/home/david/Plots/datos15.dat' with colourmap title ''
and the error says
file '/home/david/Plots/colourmap':14: Numerical Error: Could not evaluate colour expression <(3*c1-1)>. The error, encountered at character position 2, was: 'Multiplication produced an overflow error.'
file '/home/david/Plots/colourmap':14: Error: Plot has been removed from multiplot, because it generated an error.
Using inversesquare this doesn't happens
I was wrong with some ranges, sorry, everything works fine
