python matplotlib save graph as data file -


i want create python script zooms in , out of matplotlib graphs along horizontal axis. plot set of horizontal bar graphs.

i want make able take generic matplotlib graph.

i not want load image , zoom that, want zoom graph along horizontal axis. (i know how this)

is there way can save , load created graph data file or there object can save , load later?

(typically, creating graph , displaying matplotlib plt.show, graph creation takes time , not want recreate graph every time want display it)

you can use pickle package saving axes , load back.

save plot pickle file:

import pickle import matplotlib.pyplot plt ax = plt.plot([1,2,5,10]) pickle.dump(ax, open("plot.pickle", "wb"))

and load back:

import pickle import matplotlib.pyplot plt    ax = pickle.load(open("plot.pickle", "rb")) plt.show()
