I am trying to add a lineal chart toa tabPanel but I have some problems.
If I add this chart to a tab which is open by default when you load
the TabPanel I can see the chart without problems but if I add this
same chart to anothet tab that is not the main this chart is not shown
On the console I can see that the chart code is running without problems.
You can imagine a TabPanel with three different tabs, but all of them contain the same code (a chart). When I launch the browser I can only see the chart that is in the first tab (default tab or first tab that is showed), but when I select a different panel (the second or third one) , chart is not showed. If I return to the first tab I still see the chart that is contained in it.
