Chart and plot data.
You can collect data, usually in an array, and then plot the data to a graph. This process is similar to a spreadsheet that first stores the data and then generates a plot of it.
A chart appends new data points to those points already in the display to create a history. On a chart, you can see the current reading or measurement in context with data previously acquired.
To create a graph or chart, you should consider the following configurable components:
Knowing what type of data you need to display determines the type of graph or chart you should use.
|Control||Accepted Data Types||Display Examples||When to Use|
|Graph||Displays numeric, complex, X/Y, or point sample data contained in arrays and analog waveforms.||Analog waveform data acquired at a constant rate.||Use a graph for fast processes that acquire data continuously.|
|Chart||Displays numeric data contained in arrays and analog waveforms.||Analog waveform data acquired at a constant rate with a history, or buffer, of the data from previous updates.||Use a chart for processes that require a cumulative history of incremental updates to be maintained.|
|Intensity Graph||Displays 3D data on a 2D plot by using color to display the values of the third dimension.||Patterned data, such as frequency of sound intensity.||Use an intensity graph for 3D data.|
|Polar Graph||Displays arrays of complex or point data composed of angle and radius values.||Point data that represents microphone sensitivity.||Use a polar graph for data best displayed on a continuous axis, such as rotating machinery.|
|Digital Graph||Displays digital tables and digital waveforms.||Digital lines and buses that represent a transistor-transistor logic (TTL) compatible signal.||Use a digital graph when you work with timing diagrams or logic analyzers.|
