绘图节点是一个可视化工具，帮助用户在大量数据中找到数据的形态。可批量生成直方图和散布图，并可以做回归及平滑直方图从布了解数据的分布情况。它和分布浏览器节点不同的是―它会从数据集合中的输入和目标变量自动的绘制图表，而图表的种类有：直方图（Bar
Charts）和散布图（Scatter Plots）等。另外，它还会预设的绘制一条在90%信赖区间内的回归线。</DIV>

<br />
<div>首先设置字体：</DIV>
<div> <a href="http://blog.photo.sina.com.cn/showpic.html#url=http://static8.photo.sina.com.cn/orignal/5d3b177cg8b8b45bb0527" TARGET="_blank"><img SRC="http://static8.photo.sina.com.cn/middle/5d3b177cg8b8b45bb0527&690" WIDTH="425" HEIGHT="239" /></A></DIV>
<br />
<div>代码：</DIV>
<div>data EMDATA.VIEW_4O9 / view=EMDATA.VIEW_4O9;</DIV>
<div> set EMSAMPLE.BUYTEST;</DIV>
<div>run;</DIV>
<div>goptions ftext=SWISS; ** 字体为SWISS;</DIV>
<div>设置图形元素：这里，我们选择画直方图</DIV>
<div> <a href="http://blog.photo.sina.com.cn/showpic.html#url=http://static3.photo.sina.com.cn/orignal/5d3b177cg8b8b46df6d32" TARGET="_blank"><img SRC="http://static3.photo.sina.com.cn/middle/5d3b177cg8b8b46df6d32&690" /></A></DIV>
<br />
<div>代码：</DIV>
<div>goptions nodisplay device=WIN htext=3 pct; **字体高度;</DIV>
<div>axis1 width=2 offset=(1,1) label=(height=4 pct rotate=90
angle=270) minor=none; **设置横轴;</DIV>
<div>axis2 width=2 label=(height=4 pct) minor=none; **设置纵轴;</DIV>
<div>pattern1 value= solid; **设置图形;</DIV>
<div><br /></DIV>
<div>作图变量选择：</DIV>
<div> <a href="http://blog.photo.sina.com.cn/showpic.html#url=http://static8.photo.sina.com.cn/orignal/5d3b177cg8b8b4856c4d7" TARGET="_blank"><img SRC="http://static8.photo.sina.com.cn/middle/5d3b177cg8b8b4856c4d7&690" /></A></DIV>
<br />
<div>代码：</DIV>
<div>proc gchart data= EMDATA.VIEW_4O9 </DIV>
<div>    
     
     
 gout= EMPROJ.DMT9GE74; **图形输出设置;</DIV>

 *图形设置：包括直方图为横向还是纵向，是否包括缺失值，按频度还是按百分比，等等；</DIV>
<div>run; </DIV>
<div><br /></DIV>
<div>*以下的设置与上面的作用完全一样，只是是针对不同的变量画直方图。在实际写代码的时候，我们可以用宏来实现；</DIV>
