The following methods enable you to access underlying iChart data:
getTagCount
getSelectedPen
getTagName
getTagDescription
getNumberOfDataPoints
getXDataValueAt
getYDataValueAt
getDatalinkValue
To return the first value of a selected data series, you can use the following script:
var myChart = document.ChartApplet.getChartObject();
var pen = myChart.getSelectedPen();
var value = myChart.getYDataValueAt(pen,1);
Note
The tag and data point numbers in the access methods start with a value of one, not zero.
