Sample Description
How to use this sample?
Move the mouse over the chart to see ExtraParam1, ExtraParam2 and ExtraParam3 details shown in the table below the chart.
How it works
Any series shown on the chart is based on the data set, the nature of the last is described in Understanding Data Model and Data Sets Configuration. Data set may contain a lot of columns, and these columns may contain any additional values could be not shown on the chart, but they can be shown in legend, tooltips or obtained via JavaScript API.
This sample shows how to obtain these values via JavaScript API. onChartMouseMove, onChartMouseOut, onChartMouseOver, onChartDraw are handled and getSeriesCustomValue is used to obtain the value of the custom field.
To understand everything about obtaining actual chart data refer to Obtaining Actual Chart Information article.
AnyChartStock JavaScript API
This sample uses the following methods, properties and events from AnyChartStock JavaScript API:
Item | Type | Description |
---|---|---|
getSeriesCustomValue | Method | Gets information about custom field of the series. |

write | Method | Adds the chart to HTML DOM as a child of the specified container. |
onChartDraw | Event | This event is dispatched when the AnyChart Stock is drawn. |
onChartMouseMove | Event | This event is dispatched when the mouse is moving over the chart plotting area. |
onChartMouseOut | Event | This event is dispatched when the mouse leaves the chart plotting area. |
onChartMouseOver | Event | This event is dispatched when the chart plotting area is hovered by the mouse. |
onSelectedRangeChange | Event | This event is dispatched when the selected range of the chart is changed. |
