Format chart axis with callback function

Setup, Configuration and Use Items & Sitemaps
1

Hi,

ECharts support callback functions e. g. in the formatter option of axisLabel. But it seems not possible to set a function as a value in the chart configuration:

config:
slots:
  yAxis:
    - component: oh-value-axis
      config:
        axisLabel:
          formatter: function (value, index) { return value * 0.1;}

Is there a way to hand over a function?

P.S.: I know I could fill another item with the calculated value by a rule and use this for the chart, but the callback function would be more elegant.
