Arguments:
- [function_image],_plot_type,_vertex_type,_ymin,_ymax,_opacity,_pattern,_color1,... or
- 'formula',_resolution>=0,_plot_type,_vertex_type,_xmin,xmax,_ymin,_ymax,_opacity,_pattern,_color1,...
Description:
Draw specified function graph on selected images.
plot_type can be
{ 0=none | 1=lines | 2=splines | 3=bar }.
vertex_type can be
{ 0=none | 1=points | 2,3=crosses | 4,5=circles | 6,7=squares }.
pattern is an hexadecimal number starting with
0x which can be omitted
even if a color is specified.
Default values:
plot_type=1, vertex_type=1, ymin=ymax=0 (auto), opacity=1, pattern=(undefined)
and
color1=0.
