I created a spreadsheet with some data, In the OnlyOffice desktop edition the Graphs created include data that is not present in the document. Tried the Same archive in Google Sheets and It's correct. My assumption it is a bug.
Left one is the Graph created with Desktop Editor (wrong), left an image of the graph of google sheets(correct). Link below, can't upload the "xlsx" in attachment
