我应该在Windows窗体图表控件中选择Line还是FastLine?

看起来像是 FastLine

Line ,如果您有几百个点,请使用 东京地铁 .

The FastLine chart type is a variation of the Line chart that significantly 
reduces the   drawing time of a series that contains a very large number of 
data points. Use this chart in situations where very large data sets are used 
and rendering speed is critical.

Some charting features are omitted from the FastLine chart to improve performance. 
The features omitted include control of point level visual attributes, markers, 
data point labels, and shadows.

例如,如果你要展示 数据点。
