I've seen, I'll do it asap.

I've developed a little package to provide my own colorbar and some other
features, this is the line that I call to draw maps:

ga.contourf(varName+'*'+str(multiply), N=len(self.bounds)-1, V=self.bounds,
            clines=False, cmap=self.cmap, norm=self.norm, extend=self.extend,
            aspect=False)

where in this case:
varname = 'sconc_dust'
multiply = '1e6'
self.cmap = mpl.colors.ListedColormap(<list of colors>)

and so on ...

I don't know on what it can depends, I'll check with new version.

Thank you very much.
