+pst-bar.tex -------------------
+ v 0.93 2022/09/10
+ fix for catcode setting in the tex file (hv)
+
+ v 0.92 2008/11/26
+ some more improvements to the code (hv)
+
+ v 0.91 2008/04/16
+ Bar labels now set within parboxes to keep them from becoming too
+ long or overlapping with neighboring labels. New keys
+ ``labelalign'' and ``labelwidth'' added to control this behavior.
+ WARNING: These new features are not yet fully tested!
+
+ v 0.9 2005/10/07
+ Code now uses pst-xkey instead of pst-keyval for managing keys.
+
+ v 0.8 2005/02/13
+ Adjusted the code for stacked bar styles so the Postscript code argument to
+ \psbarscale so the Postscript code is only applied to the bottom bar.
+
+ v 0.7a 2004/09/24
+ Removed some debugging code that was accidentally left in the last release.
+ The removed code was harmless, but caused confusion for some users.
+
+ v 0.7 2004/09/15
+ Made a minor change to \psbarscale so its functionality would be more
+ closely analogous to the \pstScale command from the pstricks-add pacakge.
+ Improved documentation. Set default barstyle to list of all available
+ barstyles. First release to CTAN.
+
+ v 0.6 2004/09/09
+ Added orientation parameter and horizontal bar-drawing capability. Removed
+ erroneous correction factor for linewidth from stacked bar chart.
+
+ v 0.5 2004/09/02
+ Added header parameter for \readpsbardata. Improved handling of headers in
+ the data file -- spaces may now be included in a header item, though commas
+ still may not.
+
+ v 0.4 2004/08/29
+ Added "block" chartstyle. Updated \readpsbardata to use .csv for both
+ header and data. Introduced \psbarscale command. First release to pstricks
+ mailing list, 2004/09/01.
+
+ v 0.3 2004/08/26
+ Added command \readpsbardata to read data for bar chart directly from a
+ .csv file with the first row containing the column labels.
+
+ v 0.2a 2004/08/23
+ Changed colsep parameter name to barcolsep to avoid clash with psmatrix.
+
+ v 0.2 2004/08/22
+ Added stacked bar chart, chartstyle parameter, and introduced pst-bar.pro
+ prologue with transpose command.
+
+ v 0.1 2004/08/21
+ Clustered bar chart.
