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. \fi
