more oddities on wxt multiplot and legend toggle

[<pl...@pi...>]

Hi,

I have some more oddities on the legend toggle feature in multiplot.

I have a 2x2 plot with four lines in each, hence four legend entries.

First I note that the toggle feature is affecting all graphs at the same 
time. This is not too bad as it happens for my instance but generally 
would not make sence because there is not necessarily any link between 
line1 on plot 1 and line1 on plot 2.


The main oddity displays serveral anomalies that I suspect have the same 
single root cause.

a) I have a legend entry that is "period = FFT window" . If I click at 
the begining of the legend text it does nothing (usual gnuplot not 
really knowing text extents , I guess).

If I click progessively further along more an more lines coming into the 
toggle.
(on all four plots) . This seems to be a function if whether my 
click.x.coord is within their legend text (estimated) extent.

If I click far enough along to be in everyone's (extimated) text extent 
it toggles  all four plots  for the line I clicked on AND ANY lines 
above it in the legend.

The active area here extends right across to the end if the 
corresponding legend line segment in TOP, RIGHT plot. ie end of the 1,2 
position plot's legend box.

ie If I click on second legend entry it affects lines 1 &2 on all four 
plots. If I click on legend item 4 in 1,1 plot I get all four lines 
toggling in all four plots !!

The fun continues if I go below the line. It's almost the opposite. Now 
it toggles any line LOWER than where I click. The same general rules 
seem to apply to position with the added twist that the 2,2 postition 
plot has a top , left key position. I can now see that the active area 
goes well beyond the end of the key box and almost the end of the plot 
area.

In fact this end seems to match the RHS of where a top,right legend box 
would be (it may be picking up a value from plot 1,2 legend box.).

The bottom line of all this madness it that legend coordinate detection 
seems totally confused in the case of multiplot. I doubt it's a big 
issue to fix but it has some crazy (and amuzing) results.
