Here is an example of a Histogram plot, with a stripchart (vertically jittered) along the x side of the plot.

Alternatively, using the geom_rug function:

Of course this simplicistic method need to be adjusted in vertical position of the stripchart or rugchart (y=-2, here), and the relative proportion of points jittering.

### Boxplot with mean and standard deviation in ggPlot2 (plus Jitter)

When you create a

**boxplot**in R, it automatically computes median, first and third quartile ("*hinges*") and 95% confidence interval of median ("*notches*").
But we would like to change the default values of boxplot graphics with the

**mean**, the mean + standard deviation, the mean - S.D., the min and the max values.
Here is an example solved using

**ggplot2**package. Plus here are represented points (the single values) jittered horizontally.
