X/Y graph

Creating an X/Y graph

In order to create an X/Y graph, you must first activate a curve, which will act as a reference for the other curves. This curve is the X axis in the X/Y graph. The Evaluation > X/Y Graph command creates an X/Y view of the graph. This way, all curves have a common X axis.

The Evaluation > Standardized X/Y Graph command creates an X/Y graph of the graph with the same scale in both axes.

If you only need a certain section of the measured value curves for the X/Y graph, then select this section of the graph before selecting the command.
Selecting a range

In the X/Y graph the cursor is always positioned on the curve section nearest to the pointer. The left and right arrow keys position the cursor to the next or previous measured point. The cursor might move opposite the direction of the arrow.

Please note that this is only a different representation of the current diagram. Therefore, the X/Y graph cannot be saved. Exit the X/Y view by closing the window.

Displaying the curve pairs

Along with the X/Y graph described above, the iTNC 530 also offers the possibility of creating an X/Y graph by pairing curves together. The first curve of a pair contains the X values, and the second curve the Y values. In this graph the individual curves do not have any relation to each other. The curve sections can be scaled in the X and Y directions.

Regardless of the program options that have been set, a fixed grid with axes to the same scale is always used for this graph.

The Evaluation > X/t Graph command additionally creates an X/t graph.
