The size of the chart window may be specified in pixels with the <b>-size</b> specification.  The vertical size allotted to each element in the chart may be specified by <b>-eltsize</b>.  To display values in the chart, it must first be configuredwith chartSetQuantities and chartSetValues, then posted to the screen with chartPost.<p>If <b>-scale</b> is given, the maximum and minimum values of the quantitiesof the chart is be drawn beneath the chart bars.  <p>If <b>-valuefmt</b> is given, <i>fmt</i> is used as a <b><i><a href="../../vxworks/ref/fioLib.html#printf" >printf</a></i>(&nbsp;)</b> style formatfor displaying the value of the quantity inside the bar itself.<p>If <b>-destroy</b> is given, <i>proc</i> is used as the name of a Tcl procedure that is invoked if the chart is destroyed by the user.  The procedure is invoked with one argument: the name of the chart.<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./barchart.html#top">barchart</a></b>, chartSetQuantities, chartSetValues, chartPost, chartDestroy<hr><a name="chartSetQuantities"></a><p align=right><a href="rtnIndex.html"><i>GUI Tcl Library (UNIX) :  Tcl Procedures</i></a></p></blockquote><h1>chartSetQuantities</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  <p><strong>chartSetQuantities</strong> - establish a set of quantities to display in a chart</p><p></blockquote><h4>LOCALE</h4><blockquote><p>UNIX GUI<p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>chartSetQuantities <i>name</i> {{<i>qname</i> <i>qmin</i> <i>qmax</i>}...}</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>The named chart is directed to display the list of quantities given.

Excess values are ignored and quantitiesthat are not assigned values by this command are undisturbed.  The chartis redrawn to reflect the new values immediately.  Each item in the valuelist is itself a list.  The first element is the new value of the bar;the remaining four entries (<i>min</i>, <i>max</i>, <i>mark1</i>, <i>mark2</i>) are optional.If specified, they provide new minimum and maximum scale values for thebar, and new values for the "marks" (the little triangles that go above(<i>mark1</i>) and below (<i>mark2</i>) the bar).<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./barchart.html#top">barchart</a></b>, chartSetQuantities, chartCreate</body></html>
