how to dynamic set chart padding or another attributes?

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

if create a chart, sometimes need to change the chart padding or another config attributes.
maybe refactor changeSize(width, height) function to changeConfig(ChartCfg) then the initial config can be changed with runtime ?

What does the proposed API look like?

changeConfig(config: ChartCfg)

chart.padding = [/*...*/];
