In a 4D Chart area, you can modify a graph by selecting an object and using the features in the 4D Chart menu bar. You can select the entire graph object by clicking on it. Selecting a specific component within the composite graph object can be done with a special keystroke: Ctrl-click on Windows, and Command-click on Macintosh. For example, you can select an individual curve in a line graph, and change its color. In 4D Chart's Object menu, you can change the curve's Fill Pattern, Fill Color, Line Pattern, or Line Color.
