Overlay line series, ignoring datetime axis

[pw]

Hi,

I've a chart where there are 3 line series with the following characteristics:

Series 1: Daily data, say from 1-Jan-08 to 1-Feb-08
Series 2: Hourly data, from 24-Jan-08 to 14-Feb-08
Series 3: Half hourly data, from 2-Feb-08 to 1-Mar-08

The users could change the date range in the 3 series. When I lot in using line series, it'll show up nicely.

If I want to plot another 3 series but using different periods, say using 2007 data, the 3 new series will show up on the left side of the chart and the 3 original series will be on the right hand side due to the datetime axis.

How can I have the new series overlay above the original series? This means, the first point of the new series will start at the same place as the first point of the original series.

I've tried using

for (int i = 0; i<value.Length; i++)
{
line.Add(i, double.Parse(value.ToString()),label)
}

but I found that it wouldn't work as the 3 series overlap and have different time steps.

Also, can I use have the bottom axis showing only the label from the new series?

Thanks.

Hi pw,

The easiest way to achieve what you request is assigning different horizontal axis to the 2 series sets. As you say, you could use the bottom axis for the new ones and the top axis for the older ones. If you don't want the top axis visible you can also hide it. For more information on axes settings please read "Tutorial 4 - Axis Control". You'll find the tutorials at TeeChart's program group.
