## Contents

Do one of the following: Click a predefined error bar option, such as Error Bars with Standard Error, Error Bars with Percentage, or Error Bars with Standard Deviation. Draw error bars as lines, with fill color between error bars and data. You can remove either of these error bars by selecting them, and then pressing DELETE. For example, if you omit the line style and specify the marker, then the plot shows only the markers and no line. have a peek here
