All of those could be easily stored in small config files and reused in other plots.Īs an example I will start with the axes. ![]() ![]() 1, it is a 2D plot, including axes, a grid, line colors, and definitions of higher order Bessel functions. Let us start with the Bessel function example from the last blog entry. ( code to produce this figure, dark2.pal, xyborder.cfg, grid.cfg, mathematics.cfg) 1 Bessel functions from order zero up to six plotted with the dark2 line colors. Set style line 9 lt 1 lc rgb '#fde725' # yellowįig. Set style line 8 lt 1 lc rgb '#aadc32' # lime green Set style line 7 lt 1 lc rgb '#5cc863' # green Set style line 6 lt 1 lc rgb '#27ad81' # green Set style line 5 lt 1 lc rgb '#21908d' # blue-green Set style line 4 lt 1 lc rgb '#2c718e' # blue Set style line 3 lt 1 lc rgb '#3b518b' # blue Set style line 2 lt 1 lc rgb '#472c7a' # purple Set style line 1 lt 1 lc rgb '#440154' # dark purple Personally I would not recommend them for every kind of plot as they are a little dark if you have large areas with low values in your plot.Īs usual in the gnuplot-palettes repository they are accompanied by line style definitions using the palette colors. 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.

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 ?
