title: highcharts graphs in bootstrap tabs are not displaying properly
body: <p>I have two tabs, tab 1 and tab 2, when the page is initially loaded, the graph in the first tab is loaded at the same time, which is fitting right in <code>col-md-6</code>, now, when I click tab 2, the graph in that tab gets collapsed to almost half of the first one, I want it to also fit in the <code>col-md-6</code> right and fine, Is there anything I'm doing wrong?</p>
