Heatmap not autoscaling properly?


In trying to create a meaningful heatmap I had to filter out a data row with data incomparable to the rest.
It seems however that Views / Javascript / Heatmap somehow ignores the filter and uses the pre-filter data as the source for figuring out the data range.

I tried also with splitter just in case it would work, no luck either.

While it could be done I guess, I’d rather not be searching all cols and records for the table-max each time.

Am I missing something obvious or is this a heatmap node flaw?

Here’s a workflow with dummy data. HeatMap-not-scaling-properly.knwf (14.2 KB)

Hi there @nikitas,

you need to use Domain Calculator to refresh column domain after filtering. (Some nodes do not update domain automatically.)
