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?
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.
Mike
