Manual page for Script_examples_gallery_-_Error_bars(PL)

This page contains a series of error bar examples. If the amount of error has been calculated in advance, use proc bars. If you want ploticus to compute the mean and standard deviation, use proc rangebar with the meanmode option.
See also the vbars prefab examples and lines prefab examples.

### Example 1

mouse
Error bars to +/- one standard error were computed in advance.

### Example 2

errbar3
Simple example where mean and standard deviation were computed by proc rangebar.

### Example 3

errbar5
Multiple error bars, showing increased statistical power as sample size increases. Values computed externally, in advance.

### Example 4

errbar4
In this example, proc rangebar computed the means and standard deviations and displayed them as horizonal error bars.

### Example 5

scatterplot10
Error bars in both horizontal and vertical directions for a scatterplot.

### Example 6

errbar1
A more elaborate example. proc scatterplot was used to render points, and proc bars the error bars. The standard deviations were computed in advance.
