Hi,

are there plans for including logarithmic display of time series data? What approach would you suggest?

Hi Matthias,

It's on the list, but there's no work being done on it yet as far as I know.

It shouldn't be a difficult extension to add. If you look in the NumberAxis class there is a method translatedValue(...). In theory, if you override that method to return a value on a log scale, all the plots should continue to work. The work is then to make the tick labels work, but even that shouldn't be a huge problem.

I'll get to it oneday, but if someone else beats me to it, that would be great...

Regards,

DG.
