Leila Etaati shows how to build a polar chart in Power BI using an R component:
I just add a layer to the above furmula “coord_polar()” this function also has been used for creating pie charts. it gets the “theta” variable, in below example I put theta=y axis, so we have below charts
Normally I don’t much like this type of polar chart, though I’m a big fan of radar charts, which follow a similar concept.
