How do I plot multiple data sets in LabVIEW?
Make sure each set of data has the same data type.
- Wire each set of data you want to plot to a Build Array node.
- Wire the appended array output from Build Array to a graph or chart indicator. If your data consists of numeric, complex, or cluster values, appended array is a 2D array.
How do you plot two graphs on the same plot in LabVIEW?
Add “Index Array” at the “yi” output of the “Interpolate 1D VI” function and expand it to two elements. Then put “Bundle” function with two inputs. Connect “Index Array” outputs to them. The resulting cluster connect to the chart.
How do you plot XY in Pscad?
- Home > PSCAD > Online Plotting and Control > XY Plots.
- Open the project in the Circuit view.
- To move an xy plot, place the mouse pointer over the title bar and then left-click and hold.
- Move the mouse pointer over one of the grips.
- Right-click over the xy plot title bar and select Cut or Copy respectively.
What is difference between waveform graph and waveform chart?
Waveform Graphs and Waveform Charts differ in the way they display and update data: A Waveform Graph accepts arrays of data in various forms, e.g. array, waveform, or dynamic data. A Waveform Chart remembers and displays a certain number of points by storing them in a buffer.
What is a waveform in LabVIEW?
The waveform data type is used by LabVIEW and other National Instrument’s software such as SignalExpress, TDMS, and the DAQmx API to display and store periodic signal measurements. The waveform data type is a cluster comprised of the following: Component. Description.
How many types of graphs are available in LabVIEW?
Mixed Signal Graphs—Display data types accepted by waveform graphs, XY graphs, and digital waveform graphs. Also accept clusters that contain any combination of those data types. 2D Graphs—Display 2D data on a 2D front panel plot. 3D Graphs—Display 3D data on a 3D front panel plot.
How do you do an XY graph in LabVIEW?
Plot XY Data from a 2D Array in LabVIEW
- Start with your data in a two dimensional (2D) array.
- Use the Index Array function to separate the array into two one-dimensional arrays — one containing x data and one containing y data.
- Bundle into a cluster which is the expected input type of the XY Graph function.
How can we plot graph on Pscad?
Adding Graphs to a Graph Frame To add one or more graphs, right-click on the frame title bar and select Add Overlay Graph (Analog) or Add PolyGraph (Analog/Digital). You can also add an overlay graph directly by pressing the Insert key on your keyboard with your mouse pointer over the graph frame.
What is an X Y plot?
An XY Plot shows a correlation between one or more paired sets of data. On an XY Plot (also called a scatter plot), the X scale shows possible values for one of the items in the pair and the Y scale shows the value of the other item in the pair. The extra data from point B is ignored.
How to plot data using multiple scales on the same graph?
It is possible to plot data using different scales by using multiple axes on the same graph. Please follow the steps below. Place the chart or graph indicator on the front panel. Right-click the axis on which you want to create multiple scales and select Duplicate Scale.
How do I change the scale of a graph in LabVIEW?
Use the Operating tool or the Labeling tool to change the horizontal or vertical scale directly. Note LabVIEW does not include hidden plots when you autoscale the axes of a graph or chart. If you want to include the hidden plots when you autoscale, make the hidden plots transparent instead.
How can I display multiple plots in the chart?
Connect “Index Array” outputs to them. The resulting cluster connect to the chart. Explanation: to display multiple plots in the chart, you need to feed it with a cluster, not an array.
Does LabVIEW include hidden plots when AutoScale the axes?
Note LabVIEW does not include hidden plots when you autoscale the axes of a graph or chart. If you want to include the hidden plots when you autoscale, make the hidden plots transparent instead.
