Customplot problem when linecolors are similar #279

Closed HenrikSpa closed 5 years ago

HenrikSpa commented 6 years ago

It's sometimes hard to see which line is which in customplot due to them getting similar colors.

Line colors seem to be set using color_list = [_num[0] for _num in np.random.rand(3,1).tolist()]

Maybe use a predefined matplotlib colorramp instead of the random one. If the same color has to be used again (due to many lines) the linestyle could be altered from '-' to '--' to double the unique styles.

Perhaps use the same approach as in the plotter-script (line 837...)? User can define a list with colors for each plot (in order) otherwise a preset list will be used try: self.plot_colors= conf.get(splot,'plot_colors').split(list_separator) except: self.plot_colors = expand_shrink_list_to_length(['r','g','b','c','m','y','k'],number_of_unique_plots)) (Same approach is used for line style and markers.)
