Hello there,

when using scientific format (e.g. ‘%-#6.2e’) for the colorbar labels (rangelabels and labels) the amount of characters for the exponent differs for the rangelabels and labels: For the rangelabels, the exponent includes a leading 0, e.g. 0.01 is shown as **1e-02** whereas for labels, the same number would be shown as **1e-2** (without the zero). I would like to have the exact same formatting for both the rangelabels and the labels with two characters in the exponent (like 1e-02). As of my understanding you cannot control the amount of characters of the exponent through printf options. Is there a way to solve this?

Thank you!

Regards,  
Oliver

PS: I use ParaView 5.9.1 on Windows 10

I fear there is no way to do that … Maybe open an issue on [our bug tracker](https://gitlab.kitware.com/paraview/paraview/-/issues)?
