Chart numeric data by displaying a history of values. How is Charting Different Than Plotting? Graphs and charts differ in the way they display and update data. VIs with a graph usually collect the data ...

Chart and plot data. 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 ...

Group data elements of a mixed type that logically belong together. What Is a Cluster? Clusters group data elements of mixed types. A cluster is similar to a record or a struct in text-based programming ...

Group elements of various data types as rows on a table. The data grid control is a 1D array of clusters. Each row of the table is one cluster, and each element in a cluster represents one column. You ...

Plot numeric, complex, X/Y, or point sample data contained in arrays and analog waveforms. What Types of Data Can I Plot? You can plot numeric, complex, or point sample data contained in arrays and analog ...

Plot 3D data on a 2D plot by using color to display the values of the third dimension. For example, you can use an intensity graph to display patterned data, such as terrain, where the magnitude represents ...

Organize the appearance of controls and indicators or display the panel of other VIs. When Should I Use a Tab Control? Tab controls are useful when you have several panel objects that are used together ...

Enter and display numeric data. Which Numeric Should I Use? Control Use Numeric control and indicator Enter or display numeric data. Slider Display numeric data in a vertical or horizontal slide with a ...

Create a list that a user can cycle through to make selections. Types of Selector Controls Types of Selector Controls Control Description Ring A ring control is a numeric input that presents a set of choices ...

Create text entry boxes and labels or enter or return the location of a file or directory. Which Text Control Should I Use? Use Control Enter string data. String Control Display string data. String Indicator ...

The following image is an example of a one-dimensional numeric array control. Index display—Determines which element to display at the top of the array control. An array index is zero-based. Element display—Value ...

An array combines data of the same data type into one data structure. An array consists of elements and dimensions. Elements are the data that make up the array. Dimensions represent the length, height, ...

Boolean data represents True and False values. On the diagram, Boolean values are represented by green objects and wires. On the panel, Boolean data is represented as switches or buttons with mechanical ...

Compare elements when you want to compare the individual corresponding elements of the input arrays or clusters. Compare aggregates when you want to compare the input arrays or clusters in their entirety. ...

By default, a data type with fewer bits changes to match the data type with more bits. If the number of bits is the same, unsigned data types are chosen over signed data types to retain as much precision ...

On the diagram, an enum appears as a pull-down list of names represented as numeric data. You can use the named values to drive the logic of your program. For example, you can wire an enum constant or ...

A red coercion dot appears on the node input where the coercion takes place. In the following diagram, a red coercion dot appears on the Add node because the node expects two inputs of matching numeric ...

You can program using a variety of numeric data types, each with different qualities and ranges. The differences among the numeric data types are the number of bits they use to store data and the data ...

Strings represent text. A string is a sequence of zero or more letters, numbers, and special characters. On the diagram, strings are represented by pink objects and wires. The string data type cannot represent ...

A two-dimensional (2D) array stores elements in a grid. It requires a column index and a row index to locate an element. 2D array controls and indicators have two index displays to navigate to specific ...

One common example of a cluster is the waveform. You might be familiar with the waveform data type if you have used it to collect data from a signal. On the diagram, waveform objects and wires appear brown. ...

Like elements of arrays, elements of a cluster are ordered. Unlike elements of arrays, the elements of a cluster are not ordered by their positions in the cluster but by the order in which the elements ...

When looking for a problem in your code, you may have an idea of the general area where the problem exists. To help focus on this area, you can use a breakpoint to pause the VI at a specified point in ...

When the results of your application are not what you expect, you can use a set of tools to determine where errors occur within your code. Although errors are often detected automatically, sometimes your ...

Execution highlighting reduces the speed of execution and displays data bubbles that move along the wires, revealing the data that each node receives when it executes. When you begin debugging a program, ...

As you create code, a broken Run button communicates that the code contains errors that prevent it from running. You can use the provided error and warning messages to help fix these problems. Errors break ...

With execution highlighting, you can see data values at a slower execution speed. However, you may want to monitor specific data values without needing to slow execution. You can use probes on specific ...

While execution highlighting slows the execution of your code, single-stepping allows you to have more control of viewing individual actions of the program. With execution highlighting, execution slows ...

After a loop completes a single iteration, sometimes you want to use the value of one of its calculations in the next loop iteration. You can use a shift register to pass data from the most recent iteration ...
