|
41
|
|
|
* |
|
42
|
|
|
* By configuring the {@link $options} property, you may specify the options |
|
43
|
|
|
* that need to be passed to the Highcharts JavaScript object. Please refer to |
|
44
|
|
|
* the demo gallery and documentation on the {@link https://www.highcharts.com/ |
|
45
|
|
|
* Highcharts website} for possible options. |
|
46
|
|
|
* |
|
47
|
|
|
* Note: You do not need to specify the <code>chart->renderTo</code> option as |
|
48
|
|
|
* is shown in many of the examples on the Highcharts website. This value is |
|
49
|
