         If you don't have the <code>stilts</code> script installed,
         write "<code>java -jar stilts.jar</code>" instead of
         "<code>stilts</code>" - see <a href="invoke.html">Section 3</a>.
         The available <code>&lt;stilts-flags&gt;</code> are listed
         in <a href="stilts-flags.html">Section 2.1</a>.
         For programmatic invocation, the Task class for this
         command is <code>uk.ac.starlink.ttools.task.TableHistogram</code>.
         
      </p>
      <p>Parameter values are assigned on the command line
         as explained in <a href="task-args.html">Section 2.3</a>.
         They are as follows:
         
      </p>
      <p>
         
         <dl>
            <dt><strong><code>antialias = true|false</code> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<em>(Boolean)</em></strong></dt>
            <dd>Controls whether lines are drawn using antialiasing,
               where applicable.
               If lines are drawn to a bitmapped-type graphics output format
               setting this parameter to true smooths the lines out by
               using gradations of colour for diagonal lines, and setting it
               false simply sets each pixel in the line to on or off.
               For vector-type graphics output formats, or for cases in which
               no diagonal lines are drawn, the setting of this parameter
               has no effect.
               Setting it true may slow the plot down slightly.
               
               <p>[Default: <code>true</code>]
               </p>

            <dt><strong><code>barstyleNS = fill|open|...</code> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<em>(BarShape)</em></strong></dt>
            <dd>Defines how histogram bars will be drawn for dataset
               NS.
               The options are:
               
               <ul>

            <dd>Adjusts the offset of the bins.
               By default zero (or one for logarithmic X axis)
               is a boundary between bins;
               other boundaries are defined by this and the bin width.
               If this value is adjusted, the lower bound of one of the bins
               will be set to this value, so all the bins move along by the
               corresponding distance.
               
               <p>[Default: <code>0.0</code>]
               </p>

            <dt><strong><code>binwidth = &lt;float-value&gt;</code> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<em>(Double)</em></strong></dt>
            <dd>Defines the width on the X axis of histogram bins.
               If the X axis is logarithmic, then this is a multiplicative
               value.
               
            </dd>

            <dd>Specifies processing to be performed on
               the table.
               The value of this parameter is one or more of the filter
               commands described in <a href="filterSteps.html">Section 6.1</a>.
               If more than one is given, they must be separated by
               semicolon characters (";").
               This parameter can be repeated multiple times on the same
               command line to build up a list of processing steps.
               The sequence of commands given in this way
               defines the processing pipeline which is performed on the table.
               
               <p>Commands may alteratively be supplied in an external file,
                  by using the indirection character '@'.
                  Thus a value of "<code>@filename</code>"
                  causes the file <code>filename</code> to be read for a list
                  of filter commands to execute.  The commands in the file
                  may be separated by newline characters and/or semicolons.

            <dd>Defines the colour of bars plotted for data set
               NS.
               The value may be a 6-digit hexadecimal number giving
               red, green and blue intensities,
               e.g. "<code>ff00ff</code>" for magenta.
               Alternatively it may be the name of one of the
               pre-defined colours.
               These are currently
               red, blue, green, grey, magenta, cyan, orange, pink, yellow, black and white.

               When false (the default), the height of each bar is determined
               by counting the number of points which fall into the range
               on the X axis that it covers.
               When true, the height is determined by counting all the points
               between negative infinity and the upper bound of the range
               on the X axis that it covers.

            <dd>Defines the dashing pattern for lines drawn for dataset
               NS.
               To generate a dashed line the value may be

               or may be a comma-separated string of on/off length values such as
               "<code>4,2,8,2</code>".
               A <code>null</code> value indicates a solid line.
