plotting a data

[tadele shiferaw]

Hello kst,

I am new to kst and I was wondering how i can make a plotter that can plot values froma simple mathematical software compoenent block that is running in parallel with the plotter in real time.

With regards

Tadele

Hi Tadele,

I'm also new to KST but I will try to answer your question as best I can.

Your "mathematical software" will need to write the data to be plotted
to a file in real time.  You will need to use one of the supported file
formats (ASCII, dirfile, CDF, netCDF, piolib, FITS, HEALPix, qimage).  
Then you point KST to this file and configure it to read any appended
data at regular intervals.

What function does your "mathematical software" perform? KST may be able
to perform this with its own built in mathematical functions or plugins.

Regards, Ben

Hi Tadele,

Ben's approach is probably what you're looking for, but as you don't give
much detail as to what you are trying to achieve,
you could also consider the possibility of a plugin, recognising this will
likely be a larger commitment of time and effort.

Kst is very extensible and with only modest programming skills you can add
either a plugin (plugins that ship with Kst can be
seen by clicking on the Data... New Plugin... menu item), which allows you
to manipulate existing vectors and scalars in some way,
or a datasource (which provides data to Kst).

Numerous examples of each can be found in
http://websvn.kde.org/branches/extragear/kde3/graphics/kst/src/plugins/
and
http://websvn.kde.org/branches/extragear/kde3/graphics/kst/src/datasources/ 
respectively.
