# Radar Chart

The data format for radar chart **per-series** is also similar but instead of x values they are variables and instead of y values they are the only values for the variables with type of Numeric.

```ruby
{
  <variable> => <value>,
  <variable> => <value>,
  ...
}
```

or this:

```ruby
[
  [<variable>, <value>],
  [<variable>, <value>],
  ...
]
```
