I have a chart which is on a page with lots of Google Visualizations.
There are:
- 8 Visualization Tables
- 1 Pie Chart
- 1 Line Chart
On initial page load, the line chart is loaded BUT it does not show the column labels OR the chart Legend (see below)

After I apply a filter (simply select any filter from a drop down I created which merely POSTS a value back to the page which then filters the data at MySQL level and rebuilds the reports - they Labels and Legend appear as expected.
It appears to only be an issue on initial Page Load. I have viewed the source of both circumstances and the ONLY difference in the code is the data that is loaded into the Chart Row Data.
