showAtX(Mixed xValue [, dataSeriesIndex = 0])

Shows toolTip at the specified x value of a dataSeries.

Parameters:
        xValue: x value for which toolTip needs to be shown.
        dataSeriesIndex: Index of dataseries for which toolTip needs to be shown. By default, dataSeriesIndex is set to 0. i.e. in case of multi-series chart, toolTip for first dataSeries will be shown. This parameter is ignored if “shared” property of toolTip is set to true – in which case toolTip content includes data for all the series.

Returns:
        Boolean: Returns true if the operation was successful. Else returns false.

Example:
        chart.toolTip.showAtX(10,0);
Note:
  • Chart should be rendered before you can use showAtX method.
  • showAtX can be used to sync toolTip across multiple charts in a page.
var chart = new  CanvasJS.Chart("container",
{
 .
 .
 toolTip: {
   // toolTip properties
 },
 .
 . 
});
chart.render();
chart.toolTip.showAtX(10,0);
