Hello, I'm looking into the possibility of using plplot for a project I'm working on and would like to ask for your collective wisdom about whether it's going to be a good match for it. The reason for asking this is that there are 2 things which I need to do in this project which don't seem to be supported by plplot currently and I'd like to know whether you think it's going to be reasonably simple to add support for them -- and also if you'd be interested in adding them to plplot. And, of course, also if I'm just missing something and if what I'm looking for is already possible, which would be the ideal answer :-)
The first of these things is the display of so-called candlestick graphs:
http://en.wikipedia.org/wiki/Candlestick_chart
This genuinely doesn't seem to be supported as it was requested before:
http://www.mail-archive.com/plplot-devel@lists.sourceforge.net/msg00650.html
http://www.mail-archive.com/plplot-devel@lists.sourceforge.net/msg00699.html
but nothing seems to have happened since then. So the question here is
mostly how realistic would it be for someone knowing nothing about plplot
internals to implement support for this new graph kind, either inside or
outside of plplot itself and if the project maintainers would be interested
in adding support for candlestick plots to plplot itself (which will give
me the excuse for asking many more questions) and, generally speaking, if
anybody has any advice about implementing this.
The second thing is that I'd like to have some degree of interactivity.
E.g. I need to allow the user to click on the y axis to draw a marker at
the given position (and then to remove it, maybe drag it around and so on).
I'll be using wxWidgets driver so I'd be able to draw everything I need on
top of the plplot output but I also need some cooperation from plplot to
translate the (pixel) coordinates in the window to the graph elements, e.g.
I need to translate them to the values on the axes. Is this already
possible and I just didn't find how to do it? If not, do you have any ideas
about how anything like this could be implemented?
Thanks in advance for any ideas!
