Add Polar/Radar Chart like we have in SSRS

RE: Add Polar/Radar Chart like we have in SSRS

I tried custom visual Radar Chart now available. But it doesn't work like I expected.

[Example]

With following data,

Name | Class | Math | History | Science | Language |
Mike | A | 5 | 3 | 5 | 2 |
Jane | A | 3 | 3 | 4 | 2 |
John | B | 2 | 5 | 3 | 4 |
Ben | B | 5 | 5 | 2 | 3 |

I would like to overlap the radar of the 4 subjects by category (classes or individuals).
In the current custom visual, I cannot find no option to get this result. I confirmed Excel can do it. It is nice to see performance change between groups acording to filitering.
