dynamic anchor/alignment/offset support

[pingcheng]

Hi,

Is there any way to make the anchor/alignment/offset dynamic but fixed? Like make it a callback or something else?

I am setting up the position of labels in the chart but for some cases the position of labels is not perfect, like the 11% in the pic

You can use scriptable options, for example (jsfiddle):

options: {
  plugins: {
    datalabels: {
      align: function(context) {
        return context.dataset.data[context.dataIndex] < 15 ? 'end' : 'start';
      },
      color: function(context) {
        return context.dataset.data[context.dataIndex] < 15 ? 'black' : 'white';
      }
      // ...
    }
  }
}

Thanks! It worked

I tried this way, maybe I missed a comma or other mistakes at that time.
