      Pareto Chart Node

      A bar chart that represents factors according to their significance with bars, combined with a line graph showing the cumulative total. Often used in quality control to highlight the most significant factors in a dataset.

      What is a Pareto Chart?

      The Pareto chart is a powerful tool for visualizing and prioritizing a range of metrics by displaying them as vertical columns ranked in descending order from highest to lowest. Additionally, it features a line that represents the cumulative total, progressing from left to right. Its primary purpose is to highlight the most significant factors contributing to a particular outcome, enabling users to focus their efforts on addressing the most impactful issues first. By presenting data in this format, the Pareto chart facilitates quick identification of the vital few metrics that have the most significant influence on a given situation, allowing for more targeted decision-making and resource allocation. Whether used for quality improvement initiatives, identifying key drivers of performance, or optimizing processes, the Pareto chart provides a clear and actionable visualization of data prioritization.

      Inputs

      The pareto chart node has both mandatory and optional inputs. These are:

      Input

      Requirement

      Comments

      Data Field Name

      Mandatory

      This is the field name within the incoming JSON payload that contains the data to be displayed on the widget.


      Each value received from this field name will appear as a column in the pareto chart.

      How to Use

      Implementation

      In the Rayven Workflow Builder:

      • Select Visualizations.
      • Drag the pareto chart node to the canvas.
      • Provide an input to the pareto chart node by connecting it to another node.
      • Double click on the pareto chart node to open the configuration window.

      Configuration

      Section: General

      This section contains basic configuration elements required for any pareto chart implementation

      Field

      Requirement

      Comments

      Widget Name

      Mandatory

      Enter a name for this node.


      This provides a handle to which you and others can refer, so it should be simple but meaningful and explain the node’s purpose.

      Widget Subtitle

      Optional

      Additional text that can be used to explain the data presented by the node. This will appear directly under the Widget Name, in a smaller text size.

      Device/Device Label Name

      Mandatory

      Select this checkbox to display the device or label name on the widget.

      X-axis Name

      Mandatory

      Enter a name for the x-axis label

      Data Field Name

      Mandatory

      This is the field name within the incoming JSON payload that contains the data to be displayed on the widget.


      Each value received from this field name will appear as a column in the pareto chart.

      Function

      Mandatory

      Select from the dropdown menu:

      • Sum
      • Count
      • Average 

      This is the calculation performed by the node that will determine the value displayed on each column.

      Relevant Percentage

      Mandatory

      The pareto chart will display a line that represents the cumulative totals of the columns, from left to right. Enter a number that represents the total percentage, which will be displayed on the right-side of the y-axis. The recommended value for this field is 100.

      Calculation Interval

      Mandatory

      Enter an integer to represent the interval for each calculation

      Units of Measurement

      Mandatory

      Enter the units of measurement to be used for the interval calculations. For example, if the following is configured:

      • X-axis time interval = 1
      • Units of measurement = Hour
      • Function = average


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

      Widget Refresh Interval (seconds)

      Optional

      Configure how often the chart widget will refresh. The default is every 60 seconds.

      Decimal Precision

      Optional

      Enter the number of decimal places to display for each column


      Section: Group by Device Label

      Field

      Requirement

      Comments

      Device label name

      Mandatory

      There are no labels available in this box until you have saved at least one in the Device Labels section of the Workspace. 


      Select a Label to use to filter devices.

      Grouped

      Mandatory

      Select a method for grouping the widget on the dashboard from the dropdown:


      No Grouping (widget per device): one widget will appear for each device


      Group by device label value (Widget per label value): One widget will appear for each value of a label. For example, if the Label is ‘Color’ and there are the values ‘Green’ and ‘Gold’, then two widgets will be displayed, one with devices with Color Label equal to “Green” and one with devices with Color Label equal to “Gold”


      Group by device label name (One widget): Only one widget will be displayed and this will contain data from all devices.
