Labview programming basics Tutorial-plotting
This Labview programming language tutorial covers
plotting tools in labview. This page covers waveform graph, waveform chart and XY graph.
This labview tutorial covers following topics:
Labview data types
Creating Array and Array operations
Cluster concepts in labview
Various plots in labview
For loop,while loop and case structure
Local variable vs Global variable concepts
The following plots are available under Controls Palette/Graph Inds and are the most widely used.
Waveform Chart: A numerical indicator that is used to display single or multiple plots and receives numerical data one value at a time. These types of plots are good to use inside loops.
Waveform Graph: Also a numerical indicator that is capable of displaying single or multiple plots; however, it receives data in an array and then plots it. These types of plots are good outside of loops and if you are not concerned with the data until all the data is collected.
XY Graph: This type of labview graph accepts two inputs in the form of cluster i.e. X and Y arrays. This graph is useful for analyzing non real-time data e.g. force vector vs distance vector.
