They are well designed to be perceptually uniform and friendly for common forms of colorblindness, so they should be save to use as your default colormap. They are freely available and now also included in the gnuplot-palettes repository on github. Especially viridis you might have seen already as this will be the new default in Matplotlib 2.0.
Matplotlib has four new colormaps called viridis, plasma, magma, and inferno. Tags: circle, colormap, dgrid3d, grid, image Set label 'very dense' at 0.3,-0.3 center front tc ls 1 Set label 'dense' at 0.5,0.75 center front tc ls 1 Set label 'normal' at -1,0.2 center front tc ls 1 R = 1.49 # make radius smaller to exclude interpolated edge points The result is then the nice circular heat map in Fig. The manually added points like xmin are removed by a smaller radius value. Plot "tmp.txt" u 1:2:(circle($1,$2,$3)) w imageįinally a few labels and the original measurement points are added. In order to limit the heat map to a circle you first extrapolate the grid using dgrid3d and store the data in a new file.Īfterwards a function is defined in order to limit the points to the inner of the circle and plot the data from the temporary file.Ĭircle(x,y,z) = sqrt(x**2+y**2)>r ?
