As an alternative to the built-in chart component or google charts, highcharts doesn't get as much credit on here as it deserves 
Someone (that will probably be me) 
should do a full guide on its usage.

Agreed, highcharts is a great and powerful tool: changing only a few parameters to have a multiaxes, multiseries graph ( by the way my phone charger is not that good.. but it works ; - )

Herewith, the very basic functionality of Highcharts in an extension, no passing of data, just displaying a simple bar chart.

(The extension is "big" because it contains the highcharts.js file, which is 273kB !)

You can remove the credit (bottom right of chart) with this option:
credits: {
enabled: false
},
Early days, I have just scratched the surface
[EDIT] in testing have now fixed the strange characters! aia provided above is now updated.

If I'm not wrong, for personal/non profit use, the credit attribution is required
P.S.
Forgot to add that I had to specify the container height explicitely, setting to automatic of fill parent, the graph was not displayed immediately, but only after rotating the phone ( not sure if this is a problem with my device )
P.P.S.
I like the heatmaps a lot ( this is a block for 'meteotemplate' )
P.P.P.S.
Also found that the 'customwebviewer' is able to return the javascript console ( which is useful in debugging )
You can always provide that somewhere else, if you do not want it on the chart itself.
I also note that dependent on use, a commercial licence may be required.
