Hi, thank you for the feedback.
A log scale, as well as other options for stats to plot, are already implemented in the full steam demo (still free if you want to try it). This version of the game is only a prototype, like a demo for the Steam demo.
The Steam demo also has a lot more content in general if you are enjoying the game, like new game modes, cards, abilities and features.
Here it is if you want to check it out: https://store.steampowered.com/app/3409750
