Pandora to add features well-established in TAChart.
Pls apply the patch. it makes several plots on one panel. What
Pandora?? I don't know Pandora, I use Laz and LCL.
First: in your patch it is not clear which curve belongs to which
function. Therefore, the next thing which will be requested it a legend.
I am 100% sure!
Second: your patch is valid only for the event panel, not for the
expression panel. Next request will be to enter several expressions
there; this requires a proper design-time editor.
And the more features are added the more requests will come up...
In essence, all these patches will add features to the plot funtion
panel which are well-established in TAChart. It is a waste of time to
bring two charting packages to a comparable level and to maintain them.
And in fact, there's even a discussion going on among the developers to
move plotfunction out of Lazarus into ccr.
Did you ever look at TAChart? It may be a bit intimidating at first
sight, but I wrote a bunch of tutorials in the wiki. I am absolutely
sure that you will master this. The function series which does what
lazplotfunction is doing (plus a lot more) is explained in
http://wiki.lazarus.freepascal.org/TAChart_Tutorial:_Function_Series.
