Hi @Anonymous ,
Do you want to display Excel file with bar graphs within PowerApps?
If you want to display Excel file with bar graphs within PowerApps, I afraid that there is no way to achieve your needs in PowerApps currently.
Currently, within PowerApps, we could only create a connection to a Excel file whose data has been formatted as a Table from an app.
As an alternative solution, I think Power BI report and Power BI tile control could achieve your needs. You could consider take a try to create same bar graphs report within Power BI based on the bar graphs in your Excel file, then pin the report to specific dashboard.
After that, you could add a Power BI tile control within your app, specify proper workspace, Dashboard and tile for it, then you could display the corresponding Power BI report within your app.
More details about displaying Power BI report in PowerApps, please check the following blog and video:
