Use percentages for an axis?

[BenWoodworth]

I want to make the y-axis use percentages instead of decimals (.5% instead of .005). The ggplot solution seems to be + scale_y_continuous(labels = scales::percent), but I can't figure out the equivalent with the Kotlin API. Is this possible/easy to do?

In the next release we are adding the "format" option to scales.
For your example you will configure the scale as:
scale_y_continuous(format=".1%")

The next release is coming soon - right after St.Patrick's I hope.

In the current version you can only format tooltips.

Hi @BenWoodworth , since v1.3.0 the formatting option is available on positional scales. Now you can write scale_y_continuous(format=".1%") to format 0.005 as .5% .

Thanks! But in this way, the tooltip format has not been changed. It's good to update the default tooltip format when scale_x/y is set?

Hi, right, formatting in tooltip is configured separately: https://github.com/JetBrains/lets-plot-kotlin/blob/master/docs/tooltips.md

However, it seems to make sense to inherit axis formatting in tooltips, thanks.

I've submitted a feature request: #229

Thanks you! :)
