The architecture for kst is to separate data aquisition from the plotting. One
application accumulates data and dumps it to a file. kst monitors the file and plots
So your application is perfect.
Start running data logger running.
start the data wizard ('w')
>From the data wizard:
enter the file name
change update type to 'time interval' if it isn't that already
click 'configure' and adjust file settings. 'OK' when done.
double click on the fields you want to plot so they appear in the right col.
set the data range to specify what you want to read.
eg, 'count from end' and range 1000 will plot the last 1000
lines of the file, shifting over as new data comes in.
(note: INDEX is the row number).
set curve placement properties.
You should have live updating plots.
