response.Write("HI")
data0 = r.getSeries(100, 100, -15, 15)
data1 = r.getSeries(100, 150, -15, 15)
data2 = r.getSeries(100, 200, -15, 15)

Hi omkar,

Are you using ChartDirector version 5.1 or an earlier version? Programmable Track Cursors is
a new feature introduced in ChartDirector version 5.1. It would not work in earlier versions
of ChartDirector.

To determine your ChartDirector version, please try the "ChartDirector/aspdemo/cdinfo.asp"
script that comes with ChartDirector. It will display the ChartDirector version you are using
(as well as some other diagnostic information).

Regards
Peter Kwan

Hi omkar,

Upgrade from ChartDirector 5.0.2 to 5.1.1 is free of charge. Your existing license key should
continue to with with ChartDirector 5.1.1. You may download the latest version from our
