Absolute magic. It took me a little while to get it set up this morning, but works like a charm.
The other views are useful as well, but we have over 50 product categories so the charts are a little lengthy.
The only thing I couldn't figure out, and I would've assumed Tableau would handle this, is the automatic changing of text colour to white on dark backgrounds. The layout is leaving all of mine in black.
Is there a setting I should be turning on?
It turns out that for heatmaps, we'll get the white and black text when weuse Show Me to build the initial heatmap, but not if we manually build it ourselves by turning on the Square Shape on the Marks Card. I set up an example in the attached, I'm also sending it to tech support.
Highlight Tables not heat map but problem solved!
