Figure 34.1 shows the facility for editing Graphs on the database. In this case, a 4 segment Graph is shown - piano2secs - which was used earlier.
It can take a fair amount of experimenting with numbers in the table to get the result you want. The 'connected segments' radio button often helps to get the various segments of the Graph following on from each other - it essentially remembers the last y-coordinate of the previous segment when it starts computing the next, and adds it to it.
This Graph shown has a positive and negative y-axis, if a 'y-axis limit lo' of 0 is entered, then the Graph has a positive y-axis only.
