Please expose a StockChartSeriesLine tag for the StockChart, so that I can set a SmoothStyle. like in the regular Chart:

<ChartSeries Type="ChartSeriesType.Area">
    <ChartSeriesLine Style="@ChartSeriesLineStyle.Smooth"></ChartSeriesLine>
</ChartSeries>

Common requirement of StockChart, or other time-based charts is to indicate events on the timeline. e.g. Dividends, stock splits, etc.

Here is an example; see the D and S events indicated on chart

To support this, we need to be able to supply a dataset of time-based events, that will be overlayed with indicators on the chart.
