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.) -- Scott Morrow Elementary Software (Now with 20% less chalk dust!) web https://elementarysoftware.com/ email sc...@elementarysoftware.com booth 1-360-734-4701 mobile 1-360-920-0715 ------------------------------------------------------ > On Feb 22, 2022, at 5:54 AM, Alex Tweedly via use-livecode > <use-livecode@lists.runrev.com> wrote: > > 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.
