Description Andrew Walker 2007-03-13 01:53:35 UTC 
Version:           HEAD (using KDE KDE 3.5.1)
Installed from:    Compiled From Sources
OS:                Linux

PROBLEM:

In cases where two vectors of different lengths are plotted one against the other the data may not be interpolated correctly. Ideally the user should be given the option of down-sampling or up-sampling.

STEPS TO REPRODUCE:

Start Kst
Select a datasource that has (for example) temperature values at 0.1 intervals sampled at 1 Hz and voltage values sampled at 5Hz. 
Plot voltage against temperature

ACTUAL RESULTS:

The temperature values are up-sampled to those of the voltage values.

EXPECTED RESULTS:

The voltage values are down-sampled to those of the temperature values.
