Adding colorbar to plot_gene_expression

[mcfefa]

Is there a way to produce colorbar with a plot using plot_gene_expression? It tried this, but it didn't work:

palantir.plot.plot_gene_expression(imp_df, tsne, ['CD34'])
plt.colorbar()

Error returned:

Color bars can be plotted by setting plot_scale=True in the palantir.plot.plot_gene_expression. Please give it a try and let us know if you run into further issues.

That worked perfectly, thanks!!
