Sorry Scott, I can't be of any help.
I hadn't tried anything like that before - and trying it in response to
your email, I have no success at all; cannot get a transparent
background. So maybe a mild confirmation that there's a problem, but
nothing better than that.
Alex.

Alex, I’m replying off list because my ulterior motive is to ask you a question.
Argh. I see, after re-reading your post, that my remarks are useless.
I’ve been spending a bit of time trying to replace my old chartsEngine library with the
new chart widget. I haven’t tried any of the commands that wrap JSON. So, ultimately I
have no answer to your question. I’ve used the more simplistic COMMA delimited [ set the
csvData of widget "Chart" to tCSVData ]. (The TAB delimited one seems to work
also.)
One thing that sometimes made a difference about what displayed was using: [ set the
lockChartUpdates of widget "Chart" to “true” ] before messing with the widget and then [
set the lockChartUpdates of widget "Chart" to “false” ] when I was done.
I suspect that you have tried this already but...
Using [ put
"cats"&COMMA&"19"&CR&"dogs"&COMMA&"12"&&CR&"gerbils"&COMMA&"5"&&CR&"wombats"&COMMA&"9"
into tCSVData ] puts “cats, dogs, gerbils and wombats” along the X-axis for me.
I found that: [ set the dataLabels of widget "Chart" to
"Cats,Dogs,Gerbils,Wombats” ] would also set the X-axis labels if it matched up with the
number of data points.
My question for you, since you’ve been messing with the widget, is about
setting the alpha / transparency of the chartBackgroundColor property. Only one
time have I seen it work as expected from the property inspector and never have
I been able to produce a transparent background by script. I was wondering if
you had tried this property. (I posted about this in bugzilla and the
mothership asked me to create a separate bug report because it worked fine for
them… I don’t have a problem creating a bug report, it just seemed odd that it
absolutely doesn’t work for me.)

I've been trying to use the new chart widget, but no success yet.
All the charts I want to do have times (or dates) along the X axis.
I can see that any options which have not been wrapped in LC can be set by
doing something like:
put the chartJSONOptions of widget "mine" into tA
put "time" into tA["scales"]["x"]["type"]
set the chartJSONOptions of widget "mine" to tA
but this still gives me
Error: This method is not implemented:
Check that a complete date adapter is provided.
and I have no idea how to provide a date adapter from LC.
Has anyone else tried date/times with more success ?
(The chart.js documentation implies there is a default adapter - so nothing
should need to be done. It also talks about installing JS libraries for other
adapters - but I don't quite get it).
Thanks,
Alex.
