I found this very interesting blog about creating a chart in a Sharepoint page:
http://letsdosharepoint.com/chart-in-sharepoint/
I tried to do this in my situation with my own list. Could not get it working. So I tried to create the exact same thing as in the example. But I make a missatke somewhre which I am not able to track.
Everything is running and executed but it ends up in an error:
<canvas id="lineChart" width="700" height="400" style="float:left;margin-right:20px;"></canvas><div id="chartDesc"></div>
TypeError: Unable to get property 'getContext' of undefined or null reference
Looks like this piece of code is not converted to proper html or someting...
return '<canvas id="lineChart" width="700" height="400" style="float:left;margin-right:20px;"></canvas><div id="chartDesc"></div>';
I'm a bit stuck now, can someone put me into the right direction?
Thanks, Mike
