Styling customization is the major flaw I see in this cute charting library. Allowing some svg parameters tune combined with some css variables override would help to overcome this limitation.
Not the highest of priorities, since this is first and foremost for internal use. There are more important issues/PRs to attend to right now. Keeping this open since it won't be hard to add.
Apparently there's possible option the allow initial measures (such as padding) override on initialization. https://github.com/frappe/charts/blob/7adc904b08fbb45fb30372d9c6a3c3df43f80085/src/js/charts/BaseChart.js#L83
