SAS SGPLOT和smoothplot出错

Question

我在尝试绘制某些数据时遇到以下错误：

         ods graphics/ANTIALIASMAX=5200;
         proc sgplot data=want;
         series x=x y=y /smoothconnect break;
                           _____________
                           22
                           202
ERROR 22-322: Syntax error, expecting one of the following: ;, ATTRID, BREAK, CLUSTERWIDTH, CURVELABEL, CURVELABELATTRS, 
              CURVELABELLOC, CURVELABELPOS, DATALABEL, DATALABELATTRS, DISCRETEOFFSET, GROUP, GROUPDISPLAY, GROUPORDER, 
              LEGENDLABEL, LINEATTRS, MARKERATTRS, MARKERS, NAME, NOMISSINGGROUP, TRANSPARENCY, URL, X2AXIS, Y2AXIS.  
ERROR 202-322: The option or parameter is not recognized and will be ignored.

我也尝试过：

 series x=x y=y /smoothconnect; break;

和

 series x=x y=y /smoothconnect;

错误保持不变，或多或少。

有人可以帮忙吗？
