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 &amp;lt;\(3\*c1-1\)&amp;gt;. 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</summary></entry></feed>
