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'.

If you pass a 'data point' to .XY SET BAR CLR, funny things happen. It creates a LAYERDGP record & saves the RID. Subsequent calls to .XY SET BAR CLR with no 'data point' will just change the colour on the LAYERDGP record, which probably isn't what the designer wanted. The colours will probably not render correctly on the chart.
