Zmin and zmax settings in the heatmap chart

Hello everyone,

we used Redash for a while and it rocks!

In our use case we use a lot of heatmap charts and we love to have more control on them.

For example, there are situations where, setting the zmin and zmax options in this chart, helps to understand when the displayed values are near the bounds of the given allowed range of z values or not.

We didn’t find a way to do it easily, so it will be very useful to add the heatmap zmin/zmax settings in the UI.

Please find a more detailed reference here:

Thanks for this great tool!

You can control those options via ‘Custom Options’ in visualization editor:

Thank you very much!
we are using v8 and “Custom Options” is not present there, so we will upgrade asap.
