Implement arrow style for a data series in a chart
In Office Excel, you have an option to implement an arrow style in your line chart for a data series.
However, it seems like the office.js library is unable to implement this option.
Excel.Line has the option I'm looking for (beginArrowheadLength, beginArrowheadStyle, etc, ), but it was strictly for shapes, completely separate from series charts, and has no way to somehow implement a custom shape to the data series.
Adding this feature would help me greatly to create a chart directly to excel instead of building a custom chart inside the page.
