Hi Mariana,
Thank you for your continued interest in Syncfusion products.
PrepareStyle Event : When a series point is about be rendered by the chart, it will raise this event and allow event subscribers to change the style used. You can handle this event to change the style attributes of a chart.
The following code snippet helps you to declare and define the PrepareStyle event in VB.NET.
AddHandler series1.PrepareStyle, AddressOf Me.ChartControlSeries_PrepareStyle
Protected Sub ChartControlSeries_PrepareStyle(sender As Object, args As ChartPrepareStyleInfoEventArgs)
{
}
With PrepareStyle event you can do the following :
1)Associate symbols,Images,text with PointIndex in different colors.
2)Different colors for each PointIndex.
3)Display the X and Y values using ToolTip.
4)Change the TextOrientation to some degree and so on.
Please try the attached sample which uses the PrepareStyle event to display the symbols on the PointIndex.
Kindly let me know if this helps.
Regards,
Jaya
