I use now on my linux machines to make publication quality scientific It's very hard to pick up colors empirically.Gnuplot is a free program that plots 2D and 3D data. I would like to plot data with points, and an approximation with lines, so, I need 20 different colors which should look nice, and colors of point and line should combine. Please, provide the example like set terminal type if it possibleĢ) Which terminal and options I should use to get the most beautiful NON-vector plot with latex text-processing? For example, if I want share my plot as just image.ģ) Are there something like color schemes for plots? For example I have 10 sets of data with approximation to plot them on single figure. Which of them I should use? Which options I should use? Could you provide some recommendations how to get good-looking plots, please?ġ) Which terminal and options I should use to get the most beautiful vector plot with latex text processing to input it in latex project later? But there are epscairo, latexcairo, latex, pslatex, tikz and another different terminals. I always use epslatex with only size option terminal in gnuplot to include my plots to latex projects. I've looked into gnuplot documentation and was horrified: there are many different terminals with tons of options. Today I face the problem of writing a big article and I need my plots to look very nice and neat.
