how to save a picture which is plotted by 'matplotlib' to a field.binary() ?

Question

Now each time I save the picture which is plotted by 'matplotlib' on hard disk and then upload it to field.binary() filed;
I want to know whether I could save the picture into field.binary() filed when it was plotted immediately.

hi Axel, thanks for your reply; I have made some try according to your advice but still failed; my main code is as below:
....
picture=fields.binary()
....
plt.figure(figsize=(8.2, 6))
plt.bar(xTem, aa, width=0.35, facecolor='lightskyblue', edgecolor='white', label='aa') xTem = [x + 0.35 for x in xTem] plt.bar(xTem, Aa, width=0.35, facecolor='yellowgreen', edgecolor='white', label='Aa')
plt.savefig('d:\a1.png')
pic_data = open('d:\a1.png', 'rb').read()
self.write({'picture': base64.encodestring(

Hi @vx2008
just get the image value data as a base64 encoded string to save it into the binary fields and you will be ok
