Stepped Stacked chart not seen as EmbeddedChart in Google sheets API? - charts

Question

I am working with a spreadsheet that contains multiple sheets. In every sheet there is 1 chart.
I am using Google Apps Script to get these specific charts, which is working perfectly for all types of charts, except for the 'Stepped Stacked Chart', not to confuse with the 'Stepped Chart'.
Example code to explain the issue:
function getCharts(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var steppedStackedSheet = ss.getSheetByName('chart_2');
var otherChart = ss.getSheetByName('chart_1');
Logger.log(steppedStackedSheet.getCharts()); // returns an empty array
Logger.log(otherChart.getCharts()); // returns an array [EmbeddedChart] - This is what i also expect to see in the steppedStackedSheet chart.
}
I am buidling a script that downloads the chart as an image, but it's strange that this specific chart is not being recognized as a chart.
Haven't found anything on Google but hopefully someone here has had a similar issue and/or a solution.
Here an example sheet, also including the script
Thanks in advance!

Answer 1

As described in this documentation,
For 100% stacking, the stacks of elements at each domain-value are rescaled such that they add up to 100%. The options for this are isStacked: 'percent', which formats each value as a percentage of 100%, and isStacked: 'relative', which formats each value as a fraction of 1. There is also an isStacked: 'absolute' option, which is functionally equivalent to isStacked: true.
You may use setStacked() which uses stacked lines, meaning that line and bar values are stacked (accumulated). By default, there is no stacking. The return type is EmbeddedColumnChartBuilder.
