Example

[Visual Basic] This sample will demonstrate how how ticks can be added at any position on an axis scale. A numeric tick is added to the y axis and a DateTime value tick is added to the x axis.

   ' * INTRO *

   ' This sample will demonstrate how how ticks can be added at any position on an axis scale.

   ' A numeric tick is added to the y axis and a DateTime value tick is added to the x axis.

   ' 1. CREATE AN AXIS TICK WITH VALUE OF 15

   Dim at As New AxisTick(15)

   at.Label.Color = Color.Red

   ' Add it to the axis.

   Chart.YAxis.ExtraTicks.Add(at)

   ' Interval is set for demo purposes so the automatic ticks dont interfere with the custom tick.

   Chart.YAxis.Interval = 10





   ' 2. CREATE AN AXIS TICK WITH VALUE OF Jan 17 2005

   Dim at2 As New AxisTick(New DateTime(2005, 1, 17))

   at2.Label.Color = Color.Red

   ' Set a format string to include the day part of the date.

   ' This sample uses random data to populate the chart. For information on acquiring

   ' database data see the following resources:
