Combination Charts - Stacked Bar Chart and Line Chart

[Darren Hevers]

Hi Guys

I am trying to create a combination chart which contains a stacked bar chart and a line chart.

I currently have the stacked bar chart working, attached is the code.

The line chart will intersect the stacked bar chart at varying points.

Any suggestions would be greatly appreciated.

Cheers

Darren

Simply create another series and don't specify the BarRenderer for
that series and it will be rendered as a line.

I tried not specifying the renderer for the series I want to plot as a line and also adding "disableStack: true" for that one, but it doesnt work. Following error occurs: 

jqplot.pointLabels.min.js:3
Uncaught TypeError: Cannot read property '0' of undefined

My questions is: Is it actually possible to create a mixture of stacked bar chart and line graph? If so, how?

Post your code on jsfiddle so we can look at it.

Hi,
okay, here is my code on jsfiddle:

https://jsfiddle.net/zb1zsnc0/2/

So I guess generally it should be feasable with jqPlot?

Your external links are not loading - look in the js console, there
are lots of errors. Fix this up and I will look at it. Also, I noticed
that you reference:

data["views"]["dates"]

But data["views"] does not exist.

Oh, I can fix that tomorrow then. The other was just a copy paste error since I deleted some other code.

But maybe it also helps you if I give you the link on my testserver where I tested that out and some other graphs. The first one is supposed to be the mixed one, you can see the code in Firebug:

The error I mentioned dissappeared for some reason but its still not working.

Thanks for your help!

I do this in many charts. For the series that are bar charts I do this:

series_options.push({
renderer: $.jqplot.BarRenderer,
rendererOptions: {
fillToZero: true,
barDirection: 'vertical',
shadowAlpha: 0,
barPadding: 0,
barMargin: 2,
},
});

and in the series that are lines I do this:

series_options.push({
color: '#00CCA3',
showMarker: true,
formatString: "",
highlighter: {
showHighlight: true,
show: true,
sizeAdjust: 2,
tooltipAxes: 'y',
showTooltip: true,
},
});

To debug your issue I would build up the chart one data set at a time
and see at which point it breaks. If that is not informative, then I'd
trace the code into jqPlot and see where it goes wrong there.

Okay, thanks for your help! I fixed it now, the problem is that I passed all the data as seperate series of label and value pairs, now I pass them as an array of one dimensional arrays and add the labels or ticks seperatly in the xaxis.
