Hi,

When placing a chart on a tab on a form, the chart is normal visible.
When moving the tab with the chart to another cell on the form, the chart is still visible.
But after checking in the form, the chart is away.

Then checking out the form again:
Under Used Widgets, the chart is visible, but on the form, the chart is lost.

I think, it 's a bug in CPF.
This happened for me already on different forms and more times.
You can prevent it by before moving the tab, to place the chart in another cell, not on a tab.
Then check in the form and check out and then move the tab and again check in and out and then place the chart again on the tab.

It happens with Firefox.
