What Is the Difference Between Graphs and Charts?
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.
Graph and Chart Components
To create a graph or chart, you should consider the following configurable components:
Style and Format
Deciding Which Graph or Chart to Use
Knowing what type of data you need to display determines the type of graph or chart you should use.
||Accepted Data Types
||When to Use
||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.
||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.
||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.
||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.
