DataMax is the software used to display data from all SPEX instruments. DataMax can present the measurements in many ways, including a contour map. A contour map displays multifiles or 3-D data, and looks much like a geographical map of heights above sea-level, or a meteorological plot of barometric pressures. X values are plotted on the horizontal axis, and z values are on the vertical axis. Y values use colors for contour depth, with darker colors for smaller y values. DataMax provides extra features, such as Contours, to change the number of contours; Interpolation, to add interpolated data along the z-axis; and Map Contour Scale, to show the level of contours.
A matrix scan (Figure 1, below) was run for the 3-D spectrum of a cocktail comprised of anthracene, perylene, and fluorescein. Following is a step-by-step procedure to present 3-D data as a contour map in DataMax.
1. In the main screen, to see the data file as a 3-D image, left-click on View, and a drop-down menu opens. Left-click on 3-D View, as in Figure 1. To see the graph, left-click on the button.
2. With the mouse, right-click on the graph itself. This opens a menu. With the mouse, highlight, then left-click on Edit Settings.
3. When the Trace Object Parameters dialog box (below) appears, click on the down arrow next to Display Mode. Then find, highlight, and left-click on Contour Map.
4. Click on the down arrow next to Line Style. Then find, highlight, and left-click on the option for Special Colors.
5. Click OK, then click . The contour map becomes the screen view, as shown below.
6. For an interpolated image of the contour map, choose the View menu, and
