Graphs
Format a graph’s axes
With the exception of pie graphs, all graphs have a value axis which displays the unit of measurement for the graph.
You can choose to display the value axis on one side or both sides of the graph. Bar, stacked bar, column, stacked
column, line, and area graphs also have a category axis which defines the categories of data in the graph.
You can control how many tick marks appear on each axis, change the length of tick marks, and add a prefix and suffix
to numbers on the axis.
1 Select the graph with the Selection tool.
2 Choose Object > Graph > Type, or double-click the graph tool in the Tools panel.
3 To change the position of the value axis, select an option from the Value Axis menu.
4 To format tick marks and labels, select an axis from the pop-up menu at the top of the dialog box, and set the
following options:
Tick Values Determines the placement of tick marks on value axes, left axes, right axes, bottom axes, or top axes.
Select Override Calculated Values to manually calculate the placement of tick marks. Either accept the values set
when you created the graph or enter a minimum value, a maximum value, and the number of divisions between
labels.
Tick Marks Determines the length of tick marks and number of tick marks per division. For category axes, select
Draw Tick Marks Between Labels to draw tick marks on either side of the labels or columns, or deselect the option
to center tick marks over the labels or columns.
Add Labels Specifies a prefix and suffix for numbers on value axes, left axes, right axes, bottom axes, or top axes.
For example, you can add a dollar sign or percent sign to axis numbers.
Assign different scales to the value axes
If your graph has a value axis on both sides, you can assign a different set of data to each axis. This causes Illustrator
to generate a different scale for each axis. This technique is especially useful when you combine different graph types
in the same graph.
1 Select the Group Selection tool .
2 Click the legend for the data set you want to assign to the axis.
3 Without moving the Group Selection tool pointer from the legend, click again. All of the columns grouped with the
legend are selected.
4 Choose Object > Graph > Type, or double-click the graph tool in the Tools panel.
5 From the Value Axis pop-up menu, select the axis to which you want to assign the data.
6 Click OK.

Format columns, bars, and lines
For column, stacked column, bar, and stacked bar graphs, you can adjust the amount of space between each column
or bar in the graph. You can also adjust the amount of space between the categories, or clusters, of data in the graph.
For line, scatter, and radar graphs, you can adjust the appearance of lines and data points.
