Image Histogram

Hello,

I would like to make an histogram of an image in gray level.
My image data is in an array (uint16array, length 220400). I would like to verify that "dimension" (from crossfilter library) is my x axis (which would be my total number of grey levels (4096), and dimensions.group would be my y axis, with the number of appeareance of each gray level.

I guess it's really simple but I just get the code and I would like to plot the bars without white spaces between them. Have you got any idea?

I would be grateful.
Thanks in advance,

Rocio

Start by reviewing the repository's histogram helper and its D3.js and Crossfilter usage. Clarify whether the requested outcome is a library change or usage documentation, then verify the intended result against the supplied uint16 image data: gray-level bins up to 4096 with bars displayed without gaps.
