Is it possible to generate a 3D iso-surface plot in plotly through its web app or the python api given a data set for a scalar variable f(x,y,z) over a regular x,y,z rectangular grid? (e.g. a temperature field in a 3D grid).

Not at the moment unfortunately. Adding support for iso-surface is on our short-term roadmap though.

At the moment, plotly surfaces have f(x,y,z) = z.

OK, thanks for that update Etienne. When you say itâ€™s on your short term roadmap, do you mean within say a couple of months?

Iâ€™m not sure I understand what you meant by f(z,y,z) = z. Did you mean f(x,y) = z ?

I meant f(x, y, z) with f being the color value.

OK, thanks Etienne.

So, any guesses on when iso-surfaces will be implemented in Plotly?

Donâ€™t worry, I wonâ€™t hold you to your prediction!

My guess best guess would be sometime this spring.
