In the Simple Scatter Graph example, when you left-click "Use Smooth for Series One"/"Use Flat for Series One", strange behavior may occur randomly. Here is a list of the different scenarios that can occur:

• Series one may disappear, while series three is unaffected.
• Series three may disappear, while series one is unaffected.
• Series one and series three may both disappear.
• Series one may appear in the location of series three with series three.
• Series one may appear in the location of series three, while series three disappears.

Steps to reproduce:

Rapidly left-click "Use Smooth for Series One"/"Use Flat for Series One". Notice that the behavior described above occurs randomly.

Expected behavior:

Left-clicking the button mentioned above should only affect whether or not the spheres in series one are smooth.
