Ardustat & Gnuplot

I’ve whipped up a little script to allow plotting of Current and Potential against time in gnuplot. By refreshing the gnuplot plot over and over again, you can achieve a “real time plot”.

This is windows specific for now, but with a few tweaks will work across all platforms

  1. Download wgnuplot and unzip (will be in a folder called “gnuplot”)
  2. Download the ardustat.plt
  3. Open wgnuplot.exe (located in the gnuplot/bin)
  4. type “dataout =” and DO NOT hit enter
  5. go to plot -> dataset and navigate to your data file (it’s ok if the ardustat is still logging)
  6. now hit enter
  7. go to file -> open and navigate to ardustat.plt
  8. you should see your data
  9. to update the plot, press the up key twice in the command prompt window, it should show “dataout = …” and hit enter, then hit the up key twice again to get the load …. line, hit enter
  10. in this way you can update the plot as it is generated
