Hi I need to use the symlog yscale in my graph, I have a lot of data that needs to be displayed linearly, with a small fraction at the upper end of the range that needs to be displayed in log scale due to its distance from the main data. The symlog scale works great, however I'd like to adjust the actual vertical graph position where it crosses from linear to log (not the threshold), because right now only ~25% of the y space is being given to linear, and I'd like it to be more like 80%. Is this possible?
Thanks!
David
Isn’t linthreshy what you are looking for? It denotes the range where the scale is linear. So, if it is 25, then from -25 to 25 the scale will be linear. After 25, it will be log.
Maybe I am missing something in your description?
Cheers!

Hi Ben,
No unfortunately linthreshy only controls the crossover point from
linear to log scale, it does not give you control over where this
occurs on the figure’s y coordinates. I’ve attached a picture to
explain, currently the linear part of the graph is only being given
around 25% of the vertical space, I’d like to reverse that and give
linear ~75% and log at the top only the remaining 25%. Is this
possible? I’ve been digging around in the SymmetricalLogScale and
SymmetricalLogLocator classes and can’t even tell how this range is
allocated.
Thanks in advance!!

David,
Thanks, that is much clearer what you are looking for. You are right, I can’t seem to find any sort of obvious way to get what you want. Reading the docs for the SymLog scale indicates to me that the author intended for the logrithmic portion to be most interesting and the linear portion was only supposed to be a work-around the whole log(0) issue. Could you file an issue on the github page so that we can mark it as a feature request?
Thanks,
Ben Root

Just getting to this after some unexpected absences. Yes – that is
how symlog was originally intended, so there isn’t currently any way
to configure it. Please file the issue and assign it to me. I’ll
have a look at what needs to be added to support this.
