Hello, I tried to generate a image stream with matplotlib and return in into html. Something like http://www.web2pyslices.com/slice/show/1357/matplotlib-howto It works perfectly. In comparison to this, I want generate several image's streams in one function, and then get it out. The idea behind this is that I have similar calculation for some images and I want it run only once time. The code should be: def plot1(type=s): xxxxxx xxxxxx return stream.getvalue() ##------------------------------------------------------------------- ##------------------------------------------------------------------- def stream_plot(): res1 = plot1(type1) res2= plot1(type2) return res1, res2 ##------------------------------------------------------------------- ##------------------------------------------------------------------- def controllerfunc(): test1,test2 = stream_plot() return dict(bc=IMG(_src=test1), bc1=IMG(_src=test2)) In the last function, bc and bc1 will be directly showed in the view like {{=bc}}, {{=bc1}} But I have a problem. Instead of image in view , I see something like "�PNG%1A���IHDR��%05�%03%7C%08%06��������%04sBIT%08%08%08%08%7C%08d����pHYs��%0Fa��%0Fa%"..
What is wrong with this code ?
