How do you display a graph in LabVIEW?
Right-click the graph and customize it using the shortcut menu items. You can configure the x- and y-scales, format the x- and y-scales, add a plot, zoom in or out, and add cursors. Build the block diagram to display data on a waveform, XY, mixed signal, or digital waveform graph.
What is an intensity graph?
An intensity graph or chart uses color to display 3D data on a 2D plot. When you set the color mapping for an intensity graph or chart, you configure the color scale of the graph or chart. The color scale consists of at least two arbitrary markers, each with a numeric value and a corresponding display color.
How do you save a waveform in LabVIEW?
To save the waveform file, select the menu option Save Waveform File, and select the Current Settings Option. This displays the dialog box shown in Fig. 30, which lets you enter the File Path, and select the Waveform File Version. Default value of the Waveform File Version is 2.0.
How do you read images in LabVIEW?
You can use the Read Bitmap File VI , Read JPEG File VI , or Read PNG File VI followed by the Draw Flattened Pixmap VI . The Read VIs are contained in the Functions»Graphics & Sound»Graphics Format palette, and the Draw VI is in Functions»Graphics & Sound»Picture Functions palette.
What is the difference between waveform chart and waveform graph?
A Waveform Chart is used to plot and remember data points which are added usually one at a time. A Waveform Graph is used to plot an entire array of data (or a waveform) all at once.
What is the difference between graphs and charts in LabVIEW?
A chart is a graphical representation of data in symbols whereas graphs portray the relationship between different data in less space. Graphs and chart techniques are evolving with technological innovations. LabVIEW is a software development platform developed by National Instruments.
How do you save a waveform file?
To save the waveform file,
- Select the Save Waveform File menu and select Current Settings option to display the Save Waveform File dialog box as shown in following figure.
- In the Save Waveform File dialog box, Enter the File Path. Select the Waveform File Version.
- Click Save to save the waveform.
How do you add pictures to LabVIEW?
Switch to LabVIEW. The image is automatically available on the LabVIEW clipboard….
- In Windows Explorer, select the graphics file you want to import.
- Drag the file into the LabVIEW window and place the cursor where you want to paste it.
- Release the mouse button. The image from the file appears in LabVIEW.
How do I create an image in LabVIEW?
LabVIEW 2020 Help On the block diagram, right-click the terminal of the control or indicator for which you want to generate an image and select Create»Invoke Node»Get Image from the shortcut menu to create an Invoke Node.
What is difference between waveform Graph and waveform chart?
What are the limitations of the intensity chart and intensity graph?
The default size for an intensity chart is 128 data points. The intensity chart display can be memory intensive. The intensity graph works the same as the intensity chart, except it does not retain previous data values and does not include update modes.
How do I set the color mapping for the intensity graph?
You can set the color mapping interactively for the intensity graph and chart the same way you define the colors for a color ramp numeric control. You can set the color mapping for the intensity graph and chart programmatically by using the property node in two ways.
What are the array indexes in intensity graph?
The array indexes correspond to the lower-left vertex of the block of color. The block of color has a unit area which is the area between the two points, as defined by the array indexes. The intensity graph or chart can display up to 256 discrete colors.
How do I configure the intensity chart buffer?
Like the waveform chart, the intensity chart maintains a history of data, or buffer, from previous updates. Right-click the chart and select Chart History Length from the shortcut menu to configure the buffer.
