Sample Description
How to use this sample?
Hover points and/or change selected range using any method and see values details in the table below the chart.
How it works
This sample handles onChartMouseMove, onChartMouseOut, onChartMouseOver, onChartDraw and onSelectedRangeChange events and invokes getSeriesOpenValue, getSeriesCloseValue, getSeriesHighValue and getSeriesLowValue method to obtain values details.
These methods are intened to obtain values from four values series - Candlestick or OHLC.
To understand everything about obtaining actual chart data refer to Obtaining Actual Chart Information article.
