This module provides an interface to the GDChart library by Bruce Verderaime (see http://www.fred.net/brv/chart/). Dynamic objects: error -- Module-level exception.

chart()
chart(s, (w, h), f, l, data...)
s -- chart style
(w,h) -- dimensions of image (width, height)
f -- file object or name of file where image should be written
l -- sequence of x-axis labels
data -- one or more sequences of data values, depending on the chart style:
simple: chart(s, (w,h), f, l, d [,d...])
float bar: chart(s, (w,h), f, l, (dl,dh) [,(dl,dh)...])
combo: chart(s, (w,h), f, l, d [,d...], da)
hi-lo-close: chart(s, (w,h), f, l, (dh,dl,dc) [,(dh,dl,dc)...])
combo hlc: chart(s, (w,h), f, l, (dh,dl,dc) [,(dh,dl,dc)...], dv)
pie: chart(s, (w,h), f, l, d [, p])
missing values:
for pie charts, p is a sequence indicating which values in d are
'present' (0 or None => corresponding value in d is missing)
for other charts, None in a dataset indicates a missing value
option()
option() -- return a dictionary of current option settings option(keyword=value [,keyword=value...]) -- change one or more options keywords and type codes -- b: boolean c: color (0xRRGGBB) e: enum (GDC_*) n: number s: string *: not implemented (x): sequence of type x annotation=* label_dist=n vol_color=c annotation_font=e label_font=e xaxis=b bar_width=n label_line=b xaxis_font=e bg_color=c line_color=c xlabel_color=c bg_image=* other_threshold=n xlabel_spacing=n bg_transparent=b percent_format=s xtitle=s border=e percent_labels=e xtitle_color=c edge_color=c pie_color=(c) xtitle_font=e explode=(i) plot_color=c yaxis=b ext_color=(c) requested_yinterval=n yaxis2=b ext_vol_color=(c) requested_ymax=n yaxis_font=e format=e|(e,n) requested_ymin=n ylabel_color=c generate_img=b scatter=* ylabel_density=n grid=e|n set_color=(c) ylabel_fmt=s grid_color=c stack_type=e ylabel2_color=c hard_graphheight=n threed_angle=n ylabel2_fmt=s hard_graphwidth=n threed_depth=n ytitle=s hard_size=b thumblabel=s ytitle_color=c hard_xorig=n thumbnail=b ytitle_font=e hard_yorig=n thumbval=n ytitle2=s hlc_cap_width=n ticks=e|n ytitle2_color=c hlc_style=e title=s zeroshelf=b hold_img=b title_color=c interpolations=b title_font=e 'format' specifies the image format (default is GDC_PNG). With GDC_JPEG, you can optionally specify the image quality (0-95, or -1 for default).
