  7. Staggered axes plot with improved tic and label spacing.
  8. TABLEVIEW displays faster for large tables.


  1. MERGE accepts optional pad parameter correctly.
  2. Properties->Axis preserves entered coordinates properly.
  3. XY Bar and Step plots display properly when scrolling.
  4. GETPEAK matches a peak for every valley detected by GETVALLEY.
  5. LEGEND fixed to avoid crash when directly executed.
  6. PLOT3D plots first sample properly for all plot styles and respects line attributes.
  7. NUMROWS fixed such that numrows()==numrows(w0).
