// * 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
AxisTick at = 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
AxisTick at2 = new AxisTick(new DateTime(2005,1,17));
at2.Label.Color = Color.Red;
Chart.XAxis.ExtraTicks.Add(at2);
// Set a format string to include the day part of the date.
Chart.XAxis.FormatString = "MMM d";
// 3. GET DATA
// *DYNAMIC DATA NOTE*
// This sample uses random data to populate the chart. For information on acquiring
// database data see the following resources:
// - Classic samples folder
// - Help File > Data Tutorials
// - Sample: features/DataEngine.aspx
// Add the random data.
Chart.SeriesCollection.Add(getRandomData());
