Excel typescript update chart data series - excel

Question

I have created an office script that does some operations on excel data and creates a table. The data of this table is the input for a chart. The chart is already existing in the Excel file.
Now I need to update the data range of the chart manually whenever new items are added to the table, but I want to do this automated ofcourse.
I was not able to find any documentation on this. In VBA I can update data ranges of a chart and I tried to port that to the office script, but with no luck.
in VBA it is like this:
ActiveChart.FullSeriesCollection(1).XValues = "='summary and graph'!$A$2:$A$42"
ActiveChart.FullSeriesCollection(1).Values = "='summary and graph'!$B$2:$B$42"
ActiveChart.FullSeriesCollection(2).Values = "='summary and graph'!$C$2:$C$42"
What would be a way to do this in excel office script? What would the syntax be?
Thanks, Joris

Answer 1

Here is the code you get when you do the recording to create a chart for the table
function main(workbook: ExcelScript.Workbook) {
let selectedSheet = workbook.getActiveWorksheet();
let table1 = workbook.getTable("Table1");
// Insert chart on sheet selectedSheet with source data from table1
let chart_5 = selectedSheet.addChart(ExcelScript.ChartType.columnClustered, table1.getRange());
}
You can change the chart source data using the setData method.
You can also get the chart series collection using the getSeries method, and set Values for each series using the setValues method. Example code could be -
let seriesCollection = chart_5.getSeries();
let range = workbook.getWorksheet("summary and graph").getRange("B2:B42");
seriesCollection[0].setValues(range);
range = workbook.getWorksheet("summary and graph").getRange("C2:C42");
seriesCollection[1].setValues(range);
