<p>These functions perform plotting of 1D data. 1D means that data depended from only 1 parameter like parametric curve {x[i],y[i],z[i]}, i=1...n. By default (if absent) values of <var>x</var>[i] are equidistantly distributed in axis range, and <var>z</var>[i]=<var>Min</var>.z. The plots are drawn for each row if one of the data is the matrix. By any case the sizes of 1st dimension <strong>must be equal</strong> for all arrays <code>x.nx=y.nx=z.nx</code>.
</p>
<p>String <var>pen</var> specifies the color and style of line and marks (see <a href="mathgl_en_23.html#Line-styles">Line styles</a>). By default (<code>pen=""</code>) solid line with color from palette is used (see <a href="mathgl_en_31.html#Palette-and-colors">Palette and colors</a>). Symbol ‘<samp>!</samp>’ set to use new color from palette for each point (not for each curve, as default). String <var>opt</var> contain command options (see <a href="mathgl_en_27.html#Command-options">Command options</a>). See section <a href="mathgl_en_14.html#g_t1D-samples">1D samples</a>, for sample code and picture.
