 [Matplotlib-users] setting scientific number notation on colorbar From: Oz Nahum - 2010-05-31 23:18:39 Attachments: Message as HTML ```Hi Guys, I'm breaking my head how to use scientific numbering on color bar: I use the following code to plot data from multiple files, would be great if someone could direct me, becuase the numbers I have are 0.0013 et. and what ever I do, the number just go over each other: for i in xrange(len(data)): x,z,som=data[i]["x"],data[i]["z"],data[i]['ch2o'] som=som*MwSOM som=som*1000 x=N.unique(x) z=N.unique(z) p_w=N.unique(som) fig = plt.figure(len(data)+1+i) ax1 = fig.add_subplot(111) som=resize(som,(z.size,x.size)) v=N.arange(1.15,1.18,0.002) CS=contourf(x,z,som,cmap=cm.pink_r) cb=colorbar(CS, orientation='horizontal', shrink=1.0,aspect=33) ax1.set_title("SOM "+titles[i]) savefig('Fig'+str(i)+'.png') Thanks in advance ! -- Oz Nahum Graduate Student Zentrum für Angewandte Geologie Universität Tübingen --- Imagine there's no countries it isn't hard to do Nothing to kill or die for And no religion too Imagine all the people Living life in peace ```
