Graphs can be created after loading datasets that follow the Corelyzer Data XML Schema or plain text imports. You can select to show it as line graph, points, or cross points.
Aside from creating a graph only track shown in the last chapter, you can also create graphs by first right-clicking on a section. When you do this, a pop-up menu will appear. Select the "Graph" option. At this point the application will show a dialog window similar to Figure 7.10.
If there is data for the selected section in a given datafile then the fields will show up as selectable items, as seen in the image. Otherwise, the listing of fields will be empty. At this point simply click on the check boxes of the fields you would like to be drawn for the section. If you would like all the images on a track to display the same fields, just make sure that the “Apply to all sections in this dataset?” checkbox is enabled.
If you do not have pre-defined section imagery available, you can still plot the dataset with the “independent graph” feature. To do so, after you load the dataset files and it is shown in the “Dataset” list, right click on the dataset file that you want to plot, select “Graph...”, the similar graph dialog will show up and the heuristic graph section will be created and plot the graph in visualization screen(s). Notice that you will need to create at least a track for it (as shown in the last chapter).
The three properties of a graph that can be changed are: minimum value, maximum value and the color. The minimum and maximum displayed values can be modified. This will take affect after you hit the Apply button. If you have the “Apply to whole track?” checkbox enabled, all the sections on the track will have their minimum and maximum values modified. This is how you can make sure that the scales of all the graphs for a particular field are the same along a whole track.
In some cases, you might want to amplify the actual scale of the graph plots when you are looking data plots in great depth range. To increase or decrease the graph (vertical) scale, you can first click on the visualization canvas area, and then press '[' or ']' to decrease or increase the graph's vertical scale on the screen.
To modify the color of a graph, first select the Color button on the dialog. At this point a color selection dialog will open up. Select the desired color and press OK. The color of the graph will immediately change. The change the color of all the graphs of the same field along a single track, make sure that the Apply to whole track? checkbox is enabled and click on the Apply button.
