Pareto Chart Node

Pareto Chart Node

The Pareto chart node enables multiple metrics to be displayed using vertical columns. It ranks them in descending order (highest to lowest). The chart has a line from left to right representing the cumulative total.

Adding a Pareto Chart node to your workflow

1. First, select your desired solution and navigate to Rayven Workflow.
2. Select ‘Visualizations’ from the left-hand panel. 
3. Find the Pareto Chart node and drag it onto the canvas. 
4. Connect the Pareto Chart node to your desired input node.
5. Double click on the Pareto Chart node to open its configuration window.

Configuring your Pareto Chart node

1. First, give your node a Name. Choose something simple that clearly explains its purpose.
2. If you want, you can add a Widget Subtitle. This additional text helps explain the data presented in the node. Anything added here will appear directly under the Widget Name in a smaller font.
3. Select the Device/Device Label Name checkbox if you want the device or label name displayed on the widget.
4. Add your x-axis label to the X-axis Name field.
5. You then need to enter your Data Field Name: the field within the incoming payload that contains the data you want the widget to display. Each value received from this field name will appear as a column in the Pareto chart.
6. Choose a Function to apply based on your desired chart calculation. This function will determine the value displayed on each column. The options are sum, count, or average.
7. The Pareto Chart will show a line to represent the cumulative totals of the columns. Under Relevant Percentage, enter a number to represent this total percentage. It will appear on the right-side of the y-axis. The recommended value for this field is 100. 
8. Choose the Calculation Interval for the function to be applied over. You must enter this value as an integer. 
9. Select a Unit of Measurement for the calculation interval from the dropdown menu. These range from minutes to years.
10. You can set the number of decimal places for your data using Decimal Precision.
    

Example

If you configure the following:

X-axis time interval = 1

Units of measurement = Hour

Function = Average

The chart will calculate the average value for each column once an hour.

Grouping by Device Label

You need to select how data should be grouped and displayed on the widget. To group data by device label, you must first create at least one label in the Device Labels section of the Workspace. See Creating Device Labels and Configuring Nodes Using Labels for more information.

1. Enter your chosen device label under Device Label Name.
2. Select a method for grouping the widget on the dashboard from the dropdown options:
   • No Grouping (widget per device): one Pareto Chart widget will appear for each device.
   • Group by device label value (widget per label value): one Pareto Chart widget will appear for each unique value label. For example, if the device label is ‘Color’ and the label values are ‘Green’ and ‘Gold’, the dashboard will display two widgets. One will show data for devices labeled ‘Green’, and the other for devices labeled ‘Gold’.
   • Group by device label name (one widget): only one Pareto Chart widget will be displayed. It will contain data from all devices with the selected device label.
