[Kst] Combine date / time columns to one x-axis

[Nicolas Brisset]

Hi Alexander,

sorry for not answering before. With 2.0.7 (beta4 currently available for Windows on sf.net, otherwise from svn) you could merge time and date if the columns were separated only by whitespace (no semicolon). We'll have to see whether we can also accept a semicolon or other separator, it should be feasible.
In order to do so, in the ASCII configuration dialog you have to set in the General options Interpret Column1 as Formatted String and use as Time/Date format: dd.MM.yyyy hh:mm:ss
Doing so Column1 gets read as C time, and you can then turn on C time interpretation and time display options in the X axis dialog (double-click on the values on an X axis, then select multiple to select all plot, then select time interpretation/display options).

I hope that's clear, if not don't hesitate to ask for details.

Nicolas
