* 1. An array of numerical values. In this case, the numerical values will be

* data: [0, 5, 3, 5]
|

|
* ```

|
* `x,y`. If the first value is a string, it is applied as the name of the

||
|
* point, and the `x` value is inferred.

|
* [1, 8],

|
||
|
* few settings, see the complete options set below. If the total number of
|
||
|
* data points exceeds the series'
|
||
