Error Bars Task

Graph ► Tasks ► Error Bars

The Error Bars task helps make an error bar graph. Enter the data according to the following table.

Column Name	Explanation
X Values	The x-value for the data point and error bars. The data and error bar x-position are always identical.
Y Values	The y-value of the data (the y-location of the green dot)
Y-Delta Min	The length from the y-value of the data point to the lower part of the bar (the distance between the green dot and the blue bar).
Y-Delta Max	The length from the upper part of the bar to the y-value of the data point. (the distance between the red bar and the green dot).

Some things to note about this task are:

Click on a data graphic component (green dot, red bar or blue bar) to edit its value.
The data value (represented by the green dot) is entered in absolute value. However, the error bar data (y-delta min and y-delta max) are entered as the distance from the data point (relative values).
To assign legend labels alt-click on a column header. See Tables for additional information.

The figure below shows the error bar task.

The Trends setting in the Preferences places trend lines based upon all y-value sets so is a convenient way to observe a trend deviation interval.
