addChart not working how "Record Actions" recorded it - office-scripts

Question

I used the "Record Actions" in the Automate tab to record myself creating a chart. The Chart looks exactly how I want it to look after recording.
function main(workbook: ExcelScript.Workbook) {
let selectedSheet = workbook.getActiveWorksheet();
// Insert chart on sheet selectedSheet
let chart_24 = selectedSheet.addChart(ExcelScript.ChartType.pie, selectedSheet.getRange("A6:B7"));
}
I changed up the code a little bit so it could work when I call this Script from Power Automate.
function main(workbook: ExcelScript.Workbook) {
let sheet = workbook.getWorksheet("Dashboard");
let rng = sheet.getRange("A6:B7");
let chart_10 = sheet.addChart(ExcelScript.ChartType.pie, rng);
}
However, when I run either code above without having the data selected on the sheet, it is now giving me a bad chart like below.
This just started happening to me. I had the code working fine for me for about two months but now it is giving me the bad graph.
After testing the code, I noticed it only works when you have the data selected and the sheet open. When you run it in Power Automate ( where you can't use select() ) it will always give me the bad graph now. Ever since March 25, 2021, I have been getting the bad graph. Prior to this date, my code ran perfectly fine. How can I use a range without having to use select() so I can run it in Power Automate?

Answer 1

This is because the row and column used by pie chart are wrongly switched. You can try to click the "Switch Row/Column" button under "Chart" tab when selecting the chart to see the result.
As a workaround for Power Automate, you can use
function main(workbook: ExcelScript.Workbook) {
let sheet = workbook.getWorksheet("Sheet2");
let rng = sheet.getRange("A1:B2");
// 3rd parameter will help avoid this bug.
let chart_10 = sheet.addChart(ExcelScript.ChartType.pie, rng, ExcelScript.ChartSeriesBy.columns);
}
