Hi, I am new to matplotlib. So if I ask sth stupid, please bear with me.
I am using matplotlib to present large data set in different graph types, bar, dot, line, etc. I find that the bar graph has very bad performance. Say, I draw data points of about ten thousand. Using dot graph, it draws in a second. But using bar graph, it draws in tens of seconds. I was wondering what causes this difference. Is there a way to improve the bar graph performace? (Maybe I am not drawing it right, then, please give me a pointer) Below is a simple example: from np.random import uniform from numpy.random import uniform x = uniform(0, 10, 14000) y = uniform(0, 100, 14000) plt.plot(x, y, 'bo') plt.bar(x, y) Thanks, Kun ------------------------------------------------------------------------------ _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
