Sherzod Posted November 1, 2018 Share Posted November 1, 2018 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; Link to comment Share on other sites More sharing options...

NizamUlMulk Posted January 31, 2022 Share Posted January 31, 2022 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?
