Feature request(s) for the gradient graph for activities.
My simplest request is that you add a zero line. The actual centre of the graph is a function of the minimum and maximum gradient, which makes it difficult to estimate where the zero line is because it’s often not the centre. Alternatively, you could switch to a zero-gradient-based histogram, so that negative gradients go down.
In either case, a nice to have would be to colour positive and negative gradients differently (perhaps red for up and blue for down, or whatever colour-blind-friendly primary or secondary colours work best).
Stretch goal would be heatmap colouring the columns. Preferably this would be done with a gradient that doesn’t saturate until close to maximum or minimum, so that max and min areas really pop out.
