In Chrome I get this error when rendering a chart:
Cannot read property 'length' of null

In FireFox rendering the same page works ok.

Can I have more information? Maybe some code? Thank you!

I fixed it, by blindly shooting! The chart must be in div not in td as it was. When I put div in table td cell chart appeared.

CORRECT

anyway, td id="chart" is wrong. Solution to this problem is putting chart in its own div like
td > div id="chart"

I just tried to put a chart on a table and it works:

  <table>
    <tr><td id='intd'><%= render_chart @chart, 'intd' %></td></tr>
  </table>

So I don't think it's really about td or html. It is probably something else.

In any case, I don't think it's a bug on the gem too, so I am closing this for now. Thank you!
