Chart widget and axes which are time values.

[Alex Tweedly]

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.

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.)

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.)
