Hi,

Can you open a ticket in support portal ?

You can try this approach for now:

procedure TMainForm.UniButton2Click(Sender: TObject);
var
  chartSeries: TUniLineSeries;
begin
  chartSeries := Series1;
  with UniChart1, chartSeries do
  begin
    chartSeries.Title := 'New title';
    JSInterface.JSCall('chart.getSeries()['+ IntToStr(SeriesList.IndexOf(chartSeries)) +'].setTitle', [Title])
  end;
end;

  chartSeries: TUniLineSeries;
begin
  chartSeries := Series1;
  with UniChart1, chartSeries do
  begin
    chartSeries.Title := 'New title';
    JSInterface.JSCall('chart.getSeries()['+ IntToStr(SeriesList.IndexOf(chartSeries)) +'].setTitle', [Title])
  end;
end;

This line of code throws "Cannot read properties of undefined (reading 'getSeries')"

Unichart1.JsInterface.JSCall('chart.getSeries()....')

And this line 

UniChart1.JSInterface.JSCall('chart.series.getAt('....

Cannot read properties of undefined (reading 'series')

Versión 1.50.0.1482, ExtJS version 6.6.0
How can resolve it?

Can you test it on the latest versions, and upgrade to the latest versions?
