[Matplotlib-users] color xy plot

[sordnay <so...@gm...>]

Hi all,
I'm trying to plot in 2D, 3 variables from time series, instead of volume I
want color for the third variable.
I have partial success with a scatter plot, but I'm unable to manage the
colorbar so it represents z values,
I needed to sort the variables and it's getting a bit ugly, so I though I
might be missing some other function ?
this is what I used:
            pylab.figure()
            x=self.stData[items[0]]
            y=self.stData[items[1]]
            z=self.stData[items[2]]
            points=zip(x,y)
            points3=sorted(zip(z,points))
            for i,p in enumerate(points3):
                z[i]=p[0]
                x[i]=p[1][0]
                y[i]=p[1][1]
            #colors=pylab.linspace(z.min(),z.max(),len(z)) did not work
            colors=pylab.linspace(0,1,len(z))
            pylab.scatter(x,y,c=colors,faceted=False)
            pylab.colorbar()
            pylab.show()
but even if I could get the colorbar ticks to represent z values, in fact
this is not correct as this gives every point "one" color, and this is not
correct...
