Hi ruigliu:
  I don't think the high-low-close graph is what you want. 
  To create a scatter plot with Y error bars: 1.  Set up your worksheet with X,Y, and Y-Error columns (to designate the third column as a Y-error column, double-click on the column heading.  In the Worksheet Column Format dialog box, set Plot Designation to Y Error). 2.  Select the Y and Y-Error columns and click the Scatter button on the 2D Graphs toolbar.
