Statistics Report for Pens in a Chart

When viewing trend data in runtime within TrendWorX64 Viewer, you can get a report that lists statistics relating to the data each pen is writing. You can give the report a title and can specify what, if any, heading information you want included in the report.

Headings in the report include each point name and description that appear in the chart, the number of samples taken over the trend period and used in the statistics, the average value for the trend period, the minimum and maximum values for the trend period, and the standard deviation for the trend period.

You can print it or save the report or its content to a file. You can export the report to one of the following file formats: HTML, DHTML, PDF, Excel, Tiff, RTF, or CSV. The format you choose determines how the data is formatted. For example, if you save the data to an Excel or CSV format, it is stored in columns; but when saved to an HTML or PDF format, the data is formatted as a the report you see in the dialog box below.

To set the length of the trend period before running the statistics report:

  1. Click the Period button  on the runtime TrendWorX ribbon or the corresponding button on the TrendWorX toolbar. This opens the ClosedEdit Trend Period and Rates dialog box. (Note that this button is described in detail in the Runtime Operations in TrendWorX topic.)

  2. Change the value in the Trend Period field by clicking the up and down arrows or by entering the desired value next to each time period label (Y = years, M = months, D = days, h = hours, m = minutes, and s = seconds).

To collect statistics for the past hour, change the h label to 1 and all other labels to 0 (or 00).
