The new spending chart is a great feature, but could use a bit of improvement in readability. Here are my points on this issue:
No Zero - the minimalist aesthetic is beautiful but not having a readable zero line makes it very difficult to read the chart. One way to include this would be a gradient inversion line aka lighter navy to dark to light. You’ve already used this to add mass to the chart area and it works well
No Scale - again, the wide audience range necessitates clean, simple interaction but the lack of scale forces users to try to infer their spending amounts or side-scroll instead of just looking at the chart. I’m sure there is a beautiful minimalist solution to this
Great app overall, and I’m a huge Monzo supporter. Looking forward to seeing the developer package once its out.
