Yes, if the values went below -30, then the scale would automatically change to accommodate it. On a more general note, this is a common problem when graphing widely differing values. In your case, both datasets seem to have a small range (8 for temperature, 1 for Rx level), but you are displaying these on an axis covering over 50. How to deal with this depends a lot on what your data is. In some cases you can massage the data for a better fit (eg multiply one set by 10, or add/subtract an offset). In your case, it might be worth looking at whether the second Y axis options might help - see --right-axis in the docs. It's not something I've used, but if you could shift your RxLevel up by about 40 then you'd get a much more usable graph. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
