Hi All
Is there any way to change the behaviour of legend() when using symbols in a plot? For example, the following code produces a legend, but the legend text is preceded by three '+' symbols, instead of the more traditional single '+'. While the output is not incorrect, it does look a little odd.
lp1 = plot(findgen(10), NAME='Test', LINESTYLE='None', SYMBOL='+')
lg1 = legend(TARGET=lp1, POSITION=[0.1,0.9], HORIZONTAL_ALIGNMENT='LEFT', $
/RELATIVE)

I don't think there is a way to do this by default. I wrote the following blog post that provides a possible workaround:

If you use the sample_width=0 workaround to get just one filled circle in the legend, no lines show up.

I guess that this code:
pl = plot(/TEST)
pl.getdata, x, y
pl1 = scatterplot(x,y,/OVER)
l = legend(TARGET=[pl,pl1])
is doing what you want.

I guess that this code:
pl = plot(/TEST)
pl.getdata, x, y
pl1 = scatterplot(x,y,/OVER, /SYM_FILLED)
l = legend(TARGET=[pl,pl1])
is doing what you want.
