About Chart Controls

The Chart Control lets you create the following types of multidimensional charts:

Bar charts, which can analyze up to four variables
Box charts, which can analyze up to six variables
Line charts, which can analyze up to three variables (no color variables)
Area charts, which can analyze up to three variables (no color variables)

The simplest bar chart analyzes two variables in a two-dimensional view. The following bar chart shows a simple chart analyzing weight by age. Each observation in the data set is an instance of the bar.

You can analyze a third variable in a two-dimensional bar chart by adding a color variable. Alternatively, rather than represent the third variable's values with color, you can view the chart in three dimensions and specify the third variable on the third axis.

In the following two-dimensional bar chart, the bar color represents the average level of fat for each age.

To analyze four variables, you have to use a three-dimensional view of the chart, specifying three axes variables and one color variable:

The Chart control lets you use up to three color variables.

For Line and Area Charts, the BY variable links the observations.
