Observing patterns using the Spectrum chart

This Ux chart provides a powerful tool that converts raw data into visual patterns, which you can use to identify subtle problems before they develop into major system issues. This chart works with historical data. The procedure for configuring this chart is similar to those for configuring the other charts.
Prerequisites: The system has collected enough historical data to produce a meaningful chart. Workbench or your browser is open and connected to a station, most likely a Supervisor station.
  1. Open the analytics palette and expand the Charts folder.
  2. Open a new Px view.
  3. Drag the Spectrum Chart from the palette to the Px view.
  4. Double-click the chart or right-click the chart and click Edit Properties.
    You can change the values plotted by manipulating the chart’s wire sheet properties, or by right-clicking the chart and using the properties window.
    The Properties window for the chart opens.

  5. Configure properties and click OK.
     NOTE: For best results, configure this chart with at least a height of 480 Abs or greater.  
    The framework renders the chart.

    This chart shows electrical demand values for an entire month where colored swatches indicate the actual values for a specific time and day during the month. In this case, there are 31 colored swatches horizontally at each timestamp representing each of the 31 days. The vertical size of the colored swatches vary based on the Interval property, which in this case is 30 minutes so there are 48 vertical colored swatches for each day. Notice that between midnight and 1 am as well as from 18:00 to 19:00 (6–7 p.m.), electrical demand was higher than expected for each Saturday and Sunday. This could be an anomaly or it could indicate a condition that requires further investigation. Such a spectrum chart allows an energy analyst to quickly spot a potential problem.

  6. To plot a pattern for another point, drag the point from the Nav tree to the chart.
