[Matplotlib-users] setting scientific number notation on colorbar

[Oz N. <na...@gm...>]

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 !
