Data Requirements

Select at least one Y column (or a range from at least one Y column). Ideally, select at least two Y columns (or a range of at least two Y columns). If there is an associated X column, X column supplies X values; otherwise, sampling interval of the Y column or row number is used.

Creating the Graph

Select required data.

Click the Z Color Mapped Waterfall button on the 2D Graphs toolbar.

The waterfall graph is ideal for comparing variations between multiple data sets created under similar conditions. The graph has a pseudo-3D effect, enabling you to see variations in the Z direction. Also, the color is mapped along the Z direction.

Each data set is displayed as a line data plot which is offset by a specified amount in both the X and Y direction. For details on how to customize this plot, please refer to this help topic: Customizing Waterfall Plots.
