hexbin equivalent for hexagonal binning in Igor?

Wed, 01/31/2018 - 12:10 am

Hello,

Does anyone know an implementation of hexagonal binning and display in Igor? In R there is the hexbin package which can be used to display density of points on a hexagonal grid. I'm wondering if someone has already written something that would work in Igor.

As a follow up question, the hexagon marker for graphs is "point up" and it would be nice to have a "flat edge up" version of this marker. Is it possible to specify a new marker for graphs in Igor? I guess the alternative is to plot point up hexagons X vs Y and annotate the graph so it can be rotated through 90° afterwards if flat edge up hexagons are needed.
