This may not be an answer to your question, but the Density Analysis plugin (https://plugins.qgis.org/plugins/densityanalysis/) will create a uniform set of polygons over an area of interest with a NUMPOINTS attribute of the number of points are contained within the polygon. The NUMPOINTS value can be weighted using some other attribute. It will automatically style the density map as well from a given color ramp.
