Thanks, that looks better. The only weird thing (minor) is that on the legend it puts both, pwma & pwmd, for each line. It doesn't do this for temperature.rimai wrote:I changed it so it uses a random color.
Try it again.
It's fixed, thanks again. Really like my RA equipment and appreciate all you support Roberto.rimai wrote:It's a bug. Thanks for reporting.
I fixed it. Try again.

I've had a bash at doing this in javascript. I haven't tried it with highcharts yet, but it works with a my modified version of your webcharts using d3.rimai wrote:We would need to analyze the results of the query record by record to be able to do this.
Remember that this is a SQL query.
Here's my first crack at plotting individual relay data from the decimal representation:lnevo wrote:Isnt the chart software javascript? Couldn't you massage the result of R and OR it in the js before you process the chart? Another way would be to have a separate js/php/ whatever vb..net i think that would break R up in a usable format.
The problem for me is I dont follow how the graphs get the data
But I'm sure we can get some json/xml/output to do it, or am I missing something?
I can't work out how highcharts deal with irregular data either. Others have lobbied so far ? unsuccessfully for changes re data gaps:AlanM wrote:Right. Is it because you use highstock.js instead of highchart.js? I wouldn't think so, though. Weird.
Tooltips added in this version (I'm sure this code could be written in a fraction of the number of lines).lnevo wrote:Very nice. The only thing you're missing is the mouse-overs to see the details.
