Solar MVAr requirement Plot in Excel

[KojoSincal]

Hello Team

Glad for all your advice and help thus far.
However; I need help to plot a chart in excel; I have honestly tried all I know and asked around the few experts.

I would like to plot the Cartesian chart in attached exactly as it is for the power factor.
As you can see; its origin is "1" with reducing negative and positive on each side.

I don't know how to do this in excel. Please help.
FYI; it is a grid requirement chart for PF and MVAr.

If you could do this and share the excel file; would be greatly appreciated.

Thanks.
