B<Returns:> the identifier of the created element, or C<undef> if an error occurs.
 
NOTE: You can pass to C<new()> other C<ATTRIBUTE=E<gt>'value'> or C<CALLBACKNAME=E<gt>\&func> pairs relevant
to this element - see L<IUP::Manual::02_Elements|IUP::Manual::02_Elements/"new()">.
 
=head2 Guide
 
Each plot can contain 2 or 3 B<axes> (X and Y and/or Z), a B<title>, a
B< legend> B<box>, a B<colorbar>, a B<grid>, a B<dataset> B<area> and
as many B<datasets> you want.
 
Each dataset is added using the L<PlotAdd1D|/PlotAdd1D>, L<PlotAdd2D|/PlotAdd2D>, L<PlotAdd3D|/PlotAdd3D>, 
L<PlotInsert1D|/PlotInsert1D>, L<PlotInsert2D|/PlotInsert2D>, L<PlotInsert3D|/PlotInsert3D>
L<PlotSet1D|/PlotSet1D>, L<PlotSet2D|/PlotSet2D> and L<PlotSet3D|/PlotSet3D> functions. All other plot
parameters are configured by attributes.
 
If no attribute is set, the default values were selected to best
display the plot.
 
B<IMPORTANT>: When setting attributes the plot is NOT redrawn until the
REDRAW attribute is set or a redraw event occurs.
 
The B<dataset area> is delimited by the min/max axis attributes. Data
is only plotted inside the dataset area. This area defines the 2D or 3D
plot coordinate space. The screen area is a 2D pixels coordinate space.
And finally the dataset also defines a normalized space, that means
min/max is converted to 0-1.
 
The B<legend box> is a list of the dataset names, each one drawn with
the same color of the correspondent dataset. The box is located in one
of the four corners of the dataset area.
 
The B<colorbar> is an additional axis showing the the colors used to
pseudo color the data for some plot modes.
 
The B<grid> is automatically spaced accordingly the current axis
displayed values.
 
The B<title> is always centered in the top of the plot.

I<(read-only)(non inheritable)> If not C<undef> returns the last error message reported by MathGL.
 
=item L<FONT|IUP::Manual::03_Attributes/FONT>
 
the default font used in all text
elements of the plot: title, legend and labels. Font support is done
using the libraries Freetype and FTGL, so TrueType (*.ttf) and OpenType
(*.otf) font files can be loaded. If the font is not located in the
system, then it will try to find the font file in the current
directory, or in the path from the "IUP_MGLFONTS" environment variable,
or in the path from the "MGLFONTS" global attribute, or in a system
folder. The font name will be combined with the path to compose a file
name. A full path can also be used. If the font load fail, an internal
MathGL font is used.
 
=item L<FGCOLOR|IUP::Manual::03_Attributes/FGCOLOR>
 
the default color used in all
text elements of the plot: title, legend and labels. Default: "0 0 0".
 
=item B<OPENGL>
 
L<(non inheritable)> Enable or disable the rendering in OpenGL.
Default: No. When NO the rendering is slower, but when Yes some
features does not behave as expected. See L<Known Issues|/"Known Issues">.

I<(read-only)> returns the number of dimensions of the
data: 1, 2 or 3. For planar and volumetric datasets returns the actual
size of each dimension C<count_x x count_y x count_z>, for example
"600x400x1" (planar) or "512x512x512" (volumetric).

Each plot can contain 2 B<axis> (X and Y), a B<title>, a B<legend>
B<box>, a B<grid>, a B<dataset> B<area> and as many B<datasets> you
want.
 
Each data set is added using the L<IUP::PPlotAdd |IUP::PPlotAdd> function. All other plot
parameters are configured by attributes.
 
If no attribute is set, the default values were selected to best
display the plot.
 
When setting attributes the plot is NOT redrawn until the REDRAW
attribute is set or a redraw event occurs.
 
The B<dataset area> is delimited by a margin. Data is only plotted
inside the dataset area. Axis and main title are positioned independent
of this margin. It is very important to set the margins when using axis
automatic scaling or the axis maybe hidden.
 
The B<legend box> is a list of the dataset names, each one drawn with
the same color of the correspondent dataset. The box is located in one
of the four corners of the dataset area.
 
The B<grid> is automatically spaced accordingly the current axis
displayed values.
 
The B<title> is always centered in the top of the plot.
 
The B<axis> are always positioned at the origin, except when
CrossOrigin is disabled, then it is positioned at the left-bottom. If
