Hi lijun,
As a work-around, you can mimic the error bars with a line plot with the 2-point segment connection like below. This can be done by the following script (from a 3-column worksheet):
/////////////////////////////////////////
%J=%H;
iimax=wks.maxrows;
window -t wks;
worksheet -a 1;
wks.col3.type=3; //Set the 3rd col as YErr
%K=%H;
for(ii=1;ii<=iimax;ii++) {
%(%K,1,ii*2-1)=%(%J,1,ii);
%(%K,1,ii*2)=%(%J,1,ii);
%(%K,2,ii*2-1)=%(%J,2,ii)-%(%J,3,ii);
%(%K,2,ii*2)=%(%J,2,ii)+%(%J,3,ii);
%(%K,3,ii*2-1)=1E-300;
%(%K,3,ii*2)=1E-300;
};
window -t plot;
layer -i#200 %(%K,2) %(%K,3); //Line for errors
set %(%K,2) -l 2; //2-Point Segment
set %(%K,2) -d 2; //2:Dash, 3:Dot, etc.
layer -i#200 %(%J,2); //Line from original values
layer -a;
