Matplotlib Plot Line Color Python Examples To specify a color for the plot line using matplotlib, set color parameter with the required color value. for example, color='green' sets the color of the plot line to green. and color='#ff7700' sets the plot line color with the rgb hex color value. Currently matplotlib supports pyqt pyside, pygobject, tkinter, and wxpython. when embedding matplotlib in a gui, you must use the matplotlib api directly rather than the pylab pyplot procedural interface, so take a look at the examples api directory for some example code working with the api.
