The .PIE SET SECT EDGE W subroutine sets the value in the memory files, but the rendered chart doesn't look any different. Looks like when setSectorStyle code is generated, the edge width is missing. Also, if you don't also set .PIE SET SECT SHADING, the setSectorStyle code is not generated at all, even if a width was specified.
If you explode all the sectors in a pie chart via .PIE SET SECT POSITION then you can't adust the distance on specific sectors via .PIE SET SECT EXP DIST. The generated setExplode method does not include the distance parameter or isn't being generated for individual sectors.
XY Chart - if you try to run it >1 time (ie, set Frame type to 'Repeating' in example program), the 2nd time thru will cancel with 'Error - Record Not in File - Dataset'.
