AmCharts - Change chart font size dynamically?

Question

I've noticed that the chart object has a fontSize property, but just changing it does nothing, even with invalidateSize() or validateNow() ;

I need it to be dynamically as I don't have access to the chart's creation code.

This is for AmCharts 3

Code I've tried (does nothing) :

const chart = AmCharts.charts[0];
chart.fontSize = 25;
chart.validateNow();
chart.invalidateSize()

Answer 1

试试这个 categoryAxis.renderer.labels.template.fontSize = 10;
