Hi Matt,

Currently, this is not supported - start/end caps use the width of the line and this is common for the whole control. You can work around this limitation by placing a scatter point series with two points at the start/end of the line, but this will work only for round caps. Alternatively, you can have two line series with two data points each which are very close to each other but have the same direction as the begin/end line segments.

We hope this helps - let us know if you have any questions.

Using the WPF product, can the size of a trend line's start cap and end cap be changed independently of the line's width? Or do they all use the same width information? Can I, for example, have a trend line line width of 1.0 but have start caps and end caps that are larger than 1.0?
