Rendering artifacts when panning an area chart

[iddings]

Expected Behavior

Area charts should render properly.

Current Behavior

If animations are disabled, and the zoom plugin is loaded, artifacts appear when panning out of the data range.

Initial Load:

After Panning:

Possible Solution

Not a solution, but I believe the issue to be in Chart.js, not the zoom plugin, as I've replicated the issue with my own custom zoom plugin.

Steps to Reproduce

Configure an area chart with a time x-axis (to allow panning past the range of data), and pan the data out of range.

This also occurs with just a plain linear X axis. My gut is that the filler plugin is not correctly filtering points that are off the chart area, but it only seems to happen in certain scenarios

To me, looks like it draws to the first hidden point, but fails to go to origin from there, before closing the path. Could be simple fix or not :)

This behavior comes from #7793

guess it was a simple fix after all. thanks for the quick help!
