We have an ext app based on extjs 3.4 where we have charts that are embedded within a tabpanel.
The problem is that chart axes are redrawn wrongly when you make another tab visible and then jumps back to the tab hosting the chart.
For example, here the chart is shown in the initial state
When I then move away from this tab, and then select the tab hosting the chart again the chart now looks like
Note that text on the labels for the x-axis has changed from month names to numbers and also that the formatting on the numbers on the y-axis has changed.
I haven't any listeners registered on focus or visibility so it must be some internal updation of the flash part when it becomes visible again. But why aren't the labels for the axes not correctly formatted.
