For some graphs, Minitab displays symbols at individual data values, so that you can visually assess their patterns. For other graphs, Minitab displays symbols at summary statistics, such as the mean, median, or count. You can add these symbol displays to some graphs that don't display them by default; for example, add a mean symbol to an individual value plot or add individual symbols to an interval plot. You can edit the type, color, and size of all symbols on a graph, groups of symbols on a graph, or an individual symbol.

- Select the symbols that you want to change:
- Click a symbol one time to select all points.
- If the graph has groups, click the symbol a second time to select only those points within the group.
- Click one more time to select the individual symbol.

- Choose .
- On the Attributes tab, select Custom and choose the new Type, Color, and Size.
- Click OK.

You can change the default attributes for symbols to use when creating new graphs.

- To change the default size, color, and type of symbols when groups are not represented by different symbols, choose and make the changes.
- To change the way symbol attributes are cycled when groups are represented by different symbols, choose and choose Symbol Types or Symbol and Line Colors.

If you have identical data values on your graph, symbols could hide behind each other. Jitter and offset symmetrically are options that move symbols slightly to reveal overlapping points.

Jitter is available for symbols on scatterplots, matrix plots, bubble plots, 3D scatterplots, individual value plots, interval plots, and boxplots; and for outliers on boxplots. Offset symmetrically is available for symbols on individual value plots, interval plots, and boxplots; and for outliers on boxplots. You can turn off jitter and offset symmetrically for all graphs that include them.

- Double-click a symbol and click the Identical Points or Jitter tab.
- Change the offset or jitter options.
- Click OK.

You can also specify the offset when creating the graph with command language. For example, if you want to create an individual value plot of the data in C1, use the following subcommands to specify the offset method:

- To create a graph with no offset, submit these session commands:
`INDPLOT C1; NOJITTER`. - To create a graph with jitter, submit these session commands:
`INDPLOT C1; JITTER`. - To create a graph with points offset symmetrically, submit the following session commands:
`INDPLOT C1; SOFFSET`###### Note

Symmetrical offset is the default, so the

`soffset`subcommand is optional.
