Build a Histogram from an Image Service/Raster

[Gianna_BBSRC]

Hi all, 

I'm wondering if this is even possible. 

All instructions (like this one) I can find about using the Histogram Widget use a vector layer.

I'm using a single band Image Service built from a multi-dimensional mosaic dataset and a TimeSlider.

Can anyone point me to an existing tutorial or example which uses a raster?

I'd appreciate any advice!

Cheers, 

Gianna

Hi Folks, 

I'm still trying to find a answer to this question. Does anyone have an example where someone has created a Histogram in JS using a raster layer?
