Version

Please specify what version of the library you are using: [3.2.1 ]

Please specify what version(s) of PowerPoint you are targeting: [16.37 (2020)]

Expected / Desired Behavior / Question

PPTX files should be able to open on Microsoft PowerPoint

Observed Behavior

When adding a line chart with dataLabelPosition set, Microsoft Office application asks to repair the file and fails to do it.

Code sample

slide.addChart( ppt.ChartType.line, [ { name: 'Foo', labels: ['bar'], values: [1] } ], { dataLabelPosition: 'bestFit' } );

[gitbrent]

There are lots of demo charts that utilize the dataLabelPosition option, so it's likely that 'bestFit' doesn't work well with Line Charts.

[ReimaFrgos]

bestFit isn't a valid label position for line charts:

It's used for Pie and Doughnut charts
