sas sgplot refline
SAS SGPlot procedure is used for creating various types of statistical graphics such as scatter plots, line plots, histograms, and more. The REFLINE statement in SAS SGPlot procedure is used to draw a reference line on a plot.
Here is an example of how to use the REFLINE statement in SAS SGPlot:
```
proc sgplot data=mydata;
scatter x=xvar y=yvar / markerattrs=(symbol=circlefilled);
refline 0 / axis=x lineattrs=(color=red);
run;
```
In this example, the scatter plot of `xvar` vs `yvar` is created using the `SCATTER` statement. The `REFLINE` statement is then used to draw a reference line at `y=0` using the `0` option and specify the `X` axis using the `AXIS=X` option. The color of the reference line is set to red using the `LINEATTRS` option.
sas sgplot 颜色
SAS SGPlot中可以使用以下方法设置颜色:
1.在SGPlot语句中使用COLOR=选项来指定颜色。例如:
```
proc sgplot data=mydata;
scatter x=xvar y=yvar / color=red;
run;
```
2.在图表语句中使用具体的颜色名称或RGB颜色码。例如:
```
proc sgplot data=mydata;
scatter x=xvar y=yvar / color=blue;
line x=xvar y=yvar / lineattrs=(color='#FF0000' thickness=2);
run;
```
3.在数据集中创建一个变量来指定颜色,并在SGPlot语句中使用这个变量。例如:
```
data mydata;
set mydata;
if category='A' then color='red';
else if category='B' then color='blue';
else color='green';
run;
proc sgplot data=mydata;
scatter x=xvar y=yvar / color=color;
run;
```
4.使用SGColor等SAS颜色库来选择颜色。例如:
```
proc sgplot data=mydata;
scatter x=xvar y=yvar / color=sgcolor('Navy');
run;
```
