Hi Libby,

Check out the powFormat in the plot_modifications repo.  It'll do that.

Hi guys,

Quick question: how do I change how yt formats the number labels on the ticks on a colourbar? Rather than 0.0001, 0.001, 0.01, 0.1, and 1.0 x 1e28 I would rather the ticks were labelled 1e24, 1e25, 1e26, 1e27, and 1e28 (or even better 10 with power superscripted)!

Thank you,

Libby
