Why is X-Axis Binding to First Column When I Have Not Specified an X-Channel

[DieselPower]

Most of my data has a count column as the first column and it runs 1-n.  I am working with data files that have a time stamp as the number of seconds since 1900 or something to that effect.  If the testing stops and then restarts within one cycle the stitched together cycle file timestamp column will have a break in it.  When plotting the data, DIAdem is interpolating across this void in time rather than ignoring it.  I have not specified an X-Channel, so why is it plotting XY style instead of just plotting the points consecutively?

Timestamp data for this file plotted:

A different channel plotted which should not reference the time stamp channel in any way.

Plot area axis system.

According to your screenshots your channels are of XY type which mean they reference to a certain X channel. You can switch off the XY-channel behavior in DIAdem's general settings or change these channels in non-XY-channels in module Analysis.

If you want to see a break in your data in Report you need to have a Novalue in the channel.

It looks like the DataPlugin I made for this type of data set calls them XY channels.  When I load text tab-delimited data using my normal plugin, the channels are of type 123.  Is there any way I can edit the Excel plugin?  If not, is there an option when using the wizard to choose XY or 123?

Unfortunately, you can't edit the plugin as it is created encrypted (long time ago plugins were created in vbs syntax and were editable, what was very helpful especially for beginners - don't know why NI changed this). But you can recreate the plugin and unmark the xy-channel option (see enclosure).
