Excel for Windows has supported adding Shapes inside (not over) Charts for many years. Excel Online does not (if a Chart contains Shapes, they will not be displayed) Would it be possible to support...
agreed on this, also seems like there is no way to add the shapes online either. you can create some shapes online but they do not become part of the chart... this also means when you are embedding the charts, the shapes don't show up either...
using this method... https://support.microsoft.com/en-us/office/share-it-embed-an-excel-workbook-on-your-web-page-or-blog-from-onedrive-804e1845-5662-487e-9b38-f96307144081
