I do not know how to speak english so I asked google translate for help...

I have the problem in gnuplot, I want to get an output image, using "terminal size png 640,640", and "set output 'datafile.png' " of the graph, where I am using "plot 'datafile.dat' w rgbimage" image file, but a horrible image, see:

The output image:https://prntscr.com/fayza3

The image that is displayed in the gnuplot:https://prntscr.com/faz0k3

The output image:https://prntscr.com/fayza3

seems to use only 256 colors. Suggestion:

 set terminal png truecolor size 640,640

or

 set terminal pngcairo size 640,640
