164
for producing line plots with optional point symbols and error bars,
165
for up to four groups.<tt> </tt>
166
For the first group data points are in data fields given in <b>x</b> and <b>y</b>, and
167
optional error bar value given in <b>err</b>.<tt> </tt>
168
By default <b>x</b> is assumed to be continuous numeric, but it can be categories
169
if <b>cats</b> is specified (for chronological X data, use the
170
<a href="prefab_chron.html">
174
To display a second curve, use <b>y2</b>, <b>err2</b>, etc.<tt> </tt>
175
Same for third and fourth curves.<tt> </tt>

This prefab is based on

Standard prefab parameters
191
are all supported. <b>data</b>, <b>x</b> and <b>y</b> are required.<tt> </tt>
196
<b>name</b> is a short description for the first curve, for
197
inclusion in a legend.<tt> </tt>

<b>linedet</b> controls

229
<b>y2</b>, <b>err2</b>, <b>name2</b>, <b>linedet2</b>, <b>pointsym2</b>, and <b>fill2</b>
230
may be specified for a second curve. <b>x</b> will be used for the
231
X component of the curve.<tt> </tt>
236
<b>y3</b>, <b>err3</b>, <b>name3</b>, <b>linedet3</b>, <b>pointsym3</b>, and <b>fill3</b>
237
may be specified for a third curve. <b>x</b> will be used for the
238
X component of the curve.<tt> </tt>
243
<b>y4</b>, <b>err4</b>, <b>name4</b>, <b>linedet4</b>, <b>pointsym4</b>, and <b>fill4</b>
244
may be specified for a fourth curve. <b>x</b> will be used for the
245
X component of the curve.<tt> </tt>
250
<b>step</b> may be specified as <tt>yes</tt> to get stairstep curves.<tt> </tt>
251
This turns off point symbols. Applies to all curves.<tt> </tt>
257
<b>gapmissing</b> may be specified as <tt>yes</tt> or <tt>small</tt>.<tt> </tt>
258
If <tt>yes</tt>, missing data will cause a gap in the line (normally
259
the line connects plottable points without a gap). <tt>small</tt> is
260
the same as <tt>yes</tt> except that it leaves a small overhang.<tt> </tt>
261
Applies to all curves.<tt> </tt>
266
<b>cats</b> may be specified as <tt>yes</tt> to signify that X values
267
are categories rather than numeric.<tt> </tt>
272
<b>errcolor</b> is the error bar
273
<a href="color.html">
281
<b>errwidth</b> is the width of error bar tails (default = 0.08)
286
<b>errthick</b> is the thickness of the error bar lines (default = 0.5)
291
<b>legend</b> controls the
292
<a href="attributetypes.html#xy">
