GDCHART v0.93b
==============

Neither this, nor README, is meant to be a usage manual (currently none exists),
but they, gdchart.h, gdc.h, gdcpie.h, and the sample code are good places to start.


Differences from v0.92b
=======================

gdc.h must be included.  Also linking with gdc.o is required.
For charts (out_graph()), include gdchart.h; link with gdc_chart.o.
For PIEs (pie_gif()), include gdcpie.h; link with gdc_pie.o.

NEW FEATURES
------------
 - PIE charts!

 - Two new chart types have been added: GDC_COMBO_LINE_BAR and GDC_COMBO_LINE_AREA
   (also GDC_3DCOMBO_LINE_BAR and GDC_3DCOMBO_LINE_AREA).

 - newlines ('\n', 0x0A) are supported GDC_title
   (note: newlines are allowed in:  GDC_title, Annotation NOTES, X-axis labels,
    GDCPIE_title, PIE slice labels)

 - width option has been added to scatter points
   GDC_scatter_width has been obsoleted

 - 'printf' style formatting is available for the secondary Y axis (GDC_ylabel2_fmt)

 - a zero 'shelf' can be added to 3D charts (GDC_0Shelf)

 - values to ~10M are now supported

 - grid lines are set for 'Z'axis on charts with multiple sets

 - individual colors may be set for secondary plotting (COMBO charts): GDC_ExtVolColor


BUG FIXES
---------
 - overwriting of 3D BARs

 - scaling of multiple sets with negative values

 - XPG2 compatibility (SunOS 2.4)

 - Y-axis and Y2-axis labels overwriting titles and/or chart; running off end of GIF

 - stacking except for AREA charts (GDC_STACK_DEPTH ok)

 - annotation line w/o a note
