format for reading in date time values in input files

I'm unable to find the answer to this on google or in the mail list
archives (is there any way of searching them or do I really have to
click on each month's entry individually?):

Is kst able to read in dates or time (for use on the x-axis) of a plot
and if so then what is the format. I've tried all sorts of formats
(mostly variants of ISO time format) but am unable to make any of them
work. I see it is possible to tell kst how time is to be displayed on
the x-axis so it seems to know about time in principle.

Thanks

Robin

Re: format for reading in date time values in input files

Hi Robin,

In the kst 1.x branch if you are using a simple ascii file as your input 
data, then you can enter dates/times in a variety of numeric formats:

Julian Year
Julian Date
Standard C time
etc.

The key is after creating your plot (with the date/time on the x-axis) to 
edit the plot and in the X-axis tab check the "Interpret as" checkbox, and 
then select the relevant selection from the combobox.
You can then select the format of the displayed date/time to be displayed 
from the "Display as" combobox.

This is described in the online documentation at:

http://kst.kde.org/handbook/view-types.html#view-types-plot-xyaxis

If you're going to use this same interpretation extensively you can modify 
the default behaviour from within Kst, using the Settings... Configure 
Kst... menu item.
Then under the General tab, using the same "Interpret as", "Display as", as 
before.

Andrew

The current behavior is clearly wrong.  However, the correct behavior is not
entirely clear: the 'Tied Zoom' indicators are actually active, so you can just
tie some of them by clicking on them.  In that case, what should the tool-bar
toggle do?

I think that the Toolbar icon should be a pushbutton, not a toggle, and will
either set all of the tied zoom indicators, or unset them all, depending on if
there are more tied or un-tied plots in the current view.

(There is also the issue that the tied zoom indicators don't look pushable...
but that is a different story.)

Thoughts?

Re: format for reading in date time values in input files

Hi Andrew,

Thanks for the quick reply. Now that you've said it I suppose this is
obvious - I read the pages in the online documentation and saw the part
about defining the output but couldn't get it to read in my data since
that is in ISO date time format - but that's easy enough to change...

Maybe the documentation could make this more explicit though (ie. that
time data has to be in one of the listed formats). 

Thanks again for your help,

Robin

 --------------------

-When looking at dirfile data, if the symlink changes, kst doesn't notice
-and one has to hit reload to get it to update.  This is annoying at
-best.

---------------------
-
 Perhaps unrelated to kst, but the new symbolic link name in defile
 (replacing the defile.cur indirect file) is retarded.  It slows me down
 and the double extension is pointless.
