Some people requested me this sample, so I decided to post it on the forums. It showcases using annotations to create a cursor with moving markers that follows the mouse movements over the chart. It also shows how one could use balloon annotations to create flags on a chart.
A Chart FX for .NET 6.2 sample can be found at the following link.

I created a sample some time ago of something similar. It displays a vertical cursor. Adding a horizontal one should not be too much trouble. Hope it helps.

Please try changing the number of decimals in the Y axis. Although not visible, the Y axis is where the point labels and tooltips get their values from. chart1.AxisY.LabelsFormat.Decimals = 2;
