Currently, chart axes in Proton Sheets only support a linear scale. This makes it very hard to read charts where values span a wide range — for example, a bar chart with a few large values (e.g. rent, investments) and many small values (e.g. subscriptions, insurance) in the same dataset. The small bars all end up compressed near the axis and become visually indistinguishable, even though the underlying differences between them matter to the user.

Adding an option for a logarithmic axis scale (similar to what Google Sheets and Excel offer) would let users compress the large values and expand the small ones, making the full dataset readable in a single chart instead of having to split it into multiple charts or manually rescale the data.

Suggested implementation: a toggle/dropdown in the chart editor (e.g. under axis settings) to switch an axis between "Linear" and "Logarithmic," available at least for bar/column and line charts.
