Here is a feature I wish KST had...

The user provides a time step value (delta t), either manually or read automatically from a specific line in the data file header.  The data wizard then creates a vector for the x-axis containing the time elapsed since the first data point.  The user should also be able to select the appropriate time units (ms, s, min, hrs etc).

This is currently achieved by using an equation to scale the INDEX vector to a time time vector.

It would also be nice if the plug-ins could work directly with the time value (rather than the INDEX).  For example when using the "shift" plug-in the user should be able to shift the data left and right using the same units as the data is displayed in.

Reproducible: Didn't try




Here is an example of an ASCII data file I would like to be able to import with automatic creation of a time based x-axis:

channel names:	
17/09/2009 11:28:19 AM - Thermocouple - Dev1_ai0	17/09/2009 11:28:19 AM - Thermocouple - Dev1_ai0
start times:	
17/09/2009 11:28:21.050125	17/09/2009 11:28:21.216787
dt:	
0.250000	
data:	
1.683599E+1	1.615940E+1
1.683502E+1	1.616248E+1
1.684403E+1	1.615294E+1
1.681951E+1	1.619551E+1
1.682327E+1	1.617476E+1
1.680551E+1	1.615913E+1
1.681099E+1	1.615533E+1
1.680957E+1	1.620246E+1
1.680303E+1	1.617426E+1

etc.....

I've been looking into this feature request in more detail and decided that KST does not require it.

A better solution is to write a data plugin to read National Instruments TDMS files directly.  This plugin would import the measured samples and create a new time based vector to plot the x-axis.

I'm therefore setting this feature request to resolved.

There is no version list for "Version Fixed in".
Use Target Milestone as indicator when the bug was fixed.
Comment 3 Nicolas Brisset 2012-02-24 21:23:28 UTC
In fact, this should be handled by the forthcoming implementation of string-formatted Time input in the ASCII data source. See detailed comments in bug #243684
