With a graph active, choose Plot Value from the Graph menu. |
Fathom lets you add lines to any graph with at least one numeric attribute plotted, or to a function plot. These lines show the values you specify. For example, you can show a mean on a histogram, like this:
1. Be sure the plot is active (it has a border). It must have one numeric axis (such as a histogram or box plot as opposed to a bar chart or a scatter plot).
2. Choose Plot Value from the Graph menu. The formula editor appears.
3. Enter the formula for the value you want to plot. Generally you won't type "=". For example, enter just mean(height).
4. Close the formula editor. The value will appear on the graph as a colored line, and the numeric value will appear at the bottom of the graph. Both will change as you add to or change the data.
Note: The Plot Value command also appears on the graph's contextual menu.
