<br><b>View the lines prefab examples</a></b><br><br></center>
<p>
<b>lines</b> is a
<a href="prefabs.html">
prefab
</a>
for producing line plots with optional point symbols and error bars, for up to four groups.<tt> </tt>
For the first group data points are in data fields given in <b>x</b> and <b>y</b>, and
optional error bar value given in <b>err</b>.<tt> </tt>
By default <b>x</b> is assumed to be continuous numeric, but it can be categories
if <b>cats</b> is specified.
(For chronological X data, use the
<a href="prefab_chron.html">
chron prefab
</a>
instead.)
To display a second line, use <b>y2</b>, <b>err2</b>, etc.<tt> </tt>
Same for third and fourth lines.<tt> </tt>
