Customizing Error bars

In this example, "Error Bar Direction" of three data points will be altered to avoid overlapping.

1. Select the graph and open [Graph]-[Data]-[Y Error Bars].

2. Check "Point Setting" and select "Single" option in the [Select] frame.

3. In the [Error Bar Direction] frame, select "High" for the data points of [Series] = "1"; [X] = "1", and "2" and select "Low" for the data point of [Series] = "2"; [X] = "1".
