body: <p>I have a highchart column chart with labels rotated to -45 degree. I want to rotate the labels to -90 degree, but doing so makes my bars disappear! fiddle: <a href="http://jsfiddle.net/Snowbell92/LMEve/" rel="nofollow">http://jsfiddle.net/Snowbell92/LMEve/</a> (this one has labels rotated to -90 deg). and code:</p>

  <p>Also, I don't know if this is a separate issue, but implementing the chart inside a tab (I am using twitter bootstrap tabs) doesn't make the chart 100% wide. only if I activate firebug, then the chart expands. url: <a href="http://goo.gl/X3sNVq" rel="nofollow">http://goo.gl/X3sNVq</a> , see the tab "show stock price in graph" then "close price" (the active tab). the chart is the same one as the above. I really appreciate any help. Thanks in advance.</p>
