Hi - perhaps you do not have enough geospatial data in your index to
generate a larger image? Try setting the facet.heatpmap.gridLevel to
something higher like 4.
I've run queries like:
q=insert whatever
here&wt=json&indent=true&facet=true&facet.heatmap=geo&facet.heatmap.gridLevel=4&facet.heat
OK. I was able to get a PNG - but it looks tiny and a blob. Not sure how to
use it.
