AW: KST-Plot Windows Version - DateTime picker / data export

[Huber, Jörg]

Hello Barth,
Sorry for my late response but I’ve never got your mail, maybe blocked as spam without any notification…
I’ve found your answer today on KST mailing list archive: http://kst.kde.narkive.com/VBbwhGua/kst-data-export
Sorry about the relatively high level of silence from my end. It looks like I
will be able to spend a lot more of my subway time on kst this spring
however :-)

I can not see a way to implement this in kst currently.
-We can't currently access fields in a data source as strings.
-We can't currently trigger a python script from within kst2.
-The scripting currently doesn't have any access to mouse coordinates.

But:

Are you imagining that the external file is constantly appended to as you
move the mouse? Or would the user do something (eg, hit a key?) to
trigger an event.

I think a semi-general approach would be to add a PyKst call that would
return a structure with lots of useful state information (frame information,
cursor position, list of key/mouse events since the last call). Then a
python script could poll kst2 waiting for whatever you want, then the
python could go off and parse files to its heart's content. Sound ok?

In a couple of commutes, I could add something to PyKst to make this
possible if you think it would be useful. I think it could be pretty cool.

Are you running windows? If so, I might need some help in getting it all
working there. I /think/ python scripting works fine in windows, but... I don't
run windows (the Win 10 upgrade has managed to bork my windows
partition) myself.

Your suggestion sounds really great. Yes I’m running Windows 7.
The user should hit a key to trigger an event.
Does the windows version supports python interface or scripting?  I’m running Kst Version 2.0.8 Revision 29f1416.
Thanks a lot for your help
Kind regards
Joerg

Betreff: KST-Plot Windows Version - DateTime picker / data export


Hello Barth,

I hope you are doing fine.

I want to ask if you have got my mails dated 14th + 20th of October and have a look on it?

There are 2 features which would be nice to have in KstPlot:

1.       “DateTime picker” for Data Range additional to “Count from end/Read to end”

2.       Is there any possibility to export one or more “data of vectors” from Kst to a file (e.g. csv)

representing actual value of vector depending on cursor position of x-axis? Can this be realized with Python scripting?



I’d really appreciate if you could send me a brief answer.

Thank you very much.

I wish you and the KstPlot team best wishes for Christmas and a Happy New Year.

Best regards

Jörg
