The Colors & Markings tab is used to set up the colors that will be used in graphical output. Here you can set the colors of plot lines, as well as the graph background and foreground color and the line marking characters. You can also use this dialog to create custom colors for use in the Color Selection dialog.
Color Line 1-12 are the colors that are used to plot lines on graphs. Line 1 is used first, then 2 and so on. If there are more than 12 lines in a graph the colors will repeat.
Marking Line 1-12 are the markings that will be used on graph lines. Markings are used only if Line Markers is set in the Graphics tab.
Graph Border Color is used to draw the box around graphs, normally this is black.
Graph Gridline Color is used to draw gridlines in graphs, normally this is gray.
Graph Background Color is the color the graphs are drawn against. Making this an off-white color can provide a useful contrast in graph appearance.
Window Background Color is the background color used outside the graph proper behind labels and other test.
Show Colors in Tables, if checked will display different runs in different colors when you use the Table and Stats tools. This is a very useful way to distinguish different runs and is checked by default. The colors used are the same as those used for graphs.
Define Custom Color allows you add to the color choices in the Color Selection dialog discussed under utility dialogs later in this chapter. There are 16 custom colors you can define to be available with the Color Selection dialog. When you press this button you will see the standard Windows Color customization dialog.
Click on the custom color you want to modify, click in the color and intensity screens, or type in values for hue, saturation and luminosity (or red green and blue) and click on the "Add to Custom Colors" button. Click OK to finish, Cancel to cancel.
Macintosh
On the Macintosh when you click on the Define Custom Color button you will be prompted for the number of the color you want to change. Select a number between 1 and 16 and click OK. The number corresponds to a position in the bottom two rows of the Color Selection dialog described below. You will see the standard Macintosh color wheel dialog. Choose a color you want and click on OK.
