Re: [Gretl-devel] plotting news

I've been working recently on the GUI editor for graphs/plots.
Things in
this department may have been a little flaky lately but I think they
have now stabilized in git and snapshots. Some aspects of the layout of
the plot-editor dialog should now be better (in particular under the
"Lines" tab, where available) and I've fixed several bugs, one or two of
which were potential crashers.
So now would be a good time to test this stuff, if anyone is so
inclined. The relevant code is fresh in my mind and any required fixes
ought to come pretty quickly.
Hi,
just some random comments, not all related to any recent changes (but
this is with a Dec 18th snapshot on Windows 10):
- Two Y-axes: For the first y-axis there is an option to switch between
linear scale to log, but not for Y2. I've never needed this myself, but
I don't see any reason why this couldn't be there for Y2 as well.
- Could be my own translation issue, but I don't remember leaving it
out: In the Lines tab in the type drop-down menu only "lines/points" is
translated (to German for me), the rest is in English. Are those marked
for translation?
- Trivial placement issue: The color chooser button is placed in the
"line" row. Perhaps better to place it in the "type" row, because even
for type==dots this is relevant and active, when the other line-related
things are inactive.
- y-axis chooser (also in lines tab): There are naturally only two
options, left and right; so perhaps better to replace the drop-down menu
with radio buttons, or even just a boolean tick box?
- Add line: Entering in the formula field something like "2 * myvar"
(where myvar is a workfile series) this is accepted at first (in the
small dialog window), but the hitting 'apply' in the main graph edit
window then produces an error (as expected, but see below).
Then I have two suggestions / feature requests in this area, if it's
reasonably straightforward to implement them:
- Add line: Related to the bug above; currently this is only for
entering a "deterministic" formula. It would be useful to actually be
able to add more variables here. Currently I think the official way is
to start from scratch with an expanded set of variables -- this is OK
but not super-flexible from a user's point of view.
- Language of automatic legend entries (this has been discussed before):
People like me have the situation that they use gretl in a native
language but need English-language plots. What I mean especially is that
with two Y-axes gretl puts "(left)" and "(right)" into the legend.
Only
that it uses the translated versions, so "(links)" and "(rechts)" for
me. This is not editable in the "legend" field for the lines because it
doesn't appear there. The recommended workaround has been to restart
gretl in English, but I wonder if instead these automatic additions
could be shown in the "legend" fields, such that they become editable as
well. I hope that description was understandable.
Thanks,
SVen
