Visualization API LIne Chart and jQuery Tabs

[Shannon Whitty]

I have built some visualization tables and charts on a page and I have found an issue that I can't resolve.

I have separated tables & charts into categories using jQuery Tabs() 

On one tab (Tab 4) I have a Pie Chart and a Line Chart

When the page loads and draws all the tables/charts and Tab 4 is NOT in focus (default) - the Line Chart does not draw the Legend OR Chart Labels. (the Pie Chart Loads fine)

When Tab 4 is in focus on page load - the Line Chart draws the Legend and Labels as expected.

How? Why?

Why would labels and legend not load if the Line Chart is within a div not initially visible?

Why do they load fine on the Pie Chart in the same situation?
