Is this possible? I know similar things can be done for 3D plots ... A minimal code of what I am trying to plot is: -- trans(x) = erf(x) plot erf(x) notitle with lines -- I would like the erf function to be red for low values of x and move towards blue on high values of x, i.e. I would like a temperature-like scale. Thanks for any help!
