A 2D graph uses x and y data to plot points on the graph and connect the points, forming a two-dimensional surface view of the data. A 2D graph is a special type of XY graph.

With 2D graphs, you can visualize two-dimensional data on XY graphs because all 2D graphs are XY Graphs. Use the 2D graph properties to modify the way data appears in a 2D graph.

LabVIEW includes the following types of 2D graphs:

  • Compass Plot—Graphs vectors that emanate from the center of a compass graph.
  • Error Bar Plot—Graphs the error bar at each point above and below the line graph.
  • Feather Plot—Graphs vectors that emanate from equally spaced points along a horizontal axis.
  • XY Plot Matrix—Graphs rows and columns of scatter graphs.

    • In this document, 2D graph refers to these specialized two-dimensional graphs, rather than to the general two-dimensional visualizations in LabVIEW.

    When you add a 2D graph to the front panel, LabVIEW wires the graph on the block diagram to a helper VI. Each 2D graph has its own corresponding helper VI. The helper VI converts the input data types into the generic data type that the 2D graph accepts.
