Hi,
I suppose there are four columns in current worksheet "Book1", and the 3rd and 4th are Y errors.
From GUI, right-click on col(3) and col(4) individually and select Set as: Y Error from context menu to set them as Y Error.
Then click on the Scatter button to plot them as a Scatter plot with two Y error bars.
By Script:
plotxy (1,2:4); //Plot col(2) and col(4) as three curves
set Book1_C -o Book1_B; //Set 3rd plot to Y error of 2nd plot
set Book1_D -o Book1_B; //Set 4th plot to Y error of 2nd plot
Or
worksheet -t 3 3; //Set col(3) as Y error
worksheet -t 4 3; //Set col(4) as Y error
worksheet -s 1 0 4 0; //Select col(1)~col(4)
run.section(plot,Scatter); //Run plot.ogs
