New features:

New proc: proc pvalue for computing pvalues associated with t-test.




• proc scatterplot - new attribute colorfield allows you to control data point color directly from a data field (not involving the legend-driven technique).
  
  
• proc areadef - new attributes clickmapadjust for tweaking the overall position of grid clickmap, and catbinsadjust useful in setting up a plotting area with categories that are slid -0.5.
  
  
• proc print - new variable that is set called FOUNDROW, which lets you determine which data row contains a given value, then pass the row number to the $datarow() function
  
  
• proc catlines - column bars
  
  
• category names having embedded whitespace can now be used for positioning (use underscores in the location spec)
  
  
• prefabs - new parameters xgridskip, ygridskip, xgridblocks, ygridblocks, firststub, laststub

Bug fixes

• C coding issue - string pointer comparisons, was ok on gcc but failed on sun C compiler and others
• clickmap - double url encoding bug
• tokncpy() fix affecting win32 builds
• proc processdata action: breaks not setting NRECORDS to 0 on eof
• proc processdata - result field names are set later, allowing current field names to be used in select statements
• on clickmap tags, alt= attribute added so that output passes xml validation
• numgroup() function - contributed bugfix installed
• datetime stubs - seconds were incorrect
• clickmap urlencoding - spaces are now urlencoded to %20 (previously was +)
• direct pixel data points are now influenced by -scale
• proc catlines able to function with just one subcat (use to require at least two)
• instability related to field name headers, getfname()
• memory leak in grgd.c, Gptlist
• date stubs dislaying garbage when given unrecognized date format string
• lineplot XFINAL was incorrect
