Version 2.42 May2013

What's new page                 Earlier change logs

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
