Min/Max/Average Chart Display

When you click the Average icon in the toolbar, the currently active Multi-Chart file tab will now show charts for the calculated values of minimum, maximum and average readings, instead of the individual charts.

Switching from Average display to Standard display and vice versa, or changing the Readings Range will force the Multi-Chart to be re-drawn according to the default settings. You can then use the standard zoom controls to show the portion of the charts you want to see.

You can annotate the Average Chart in the same way as any other chart tab; such annotations will be visible in the other chart tabs and are stored with the multi chart when saved. An annotation that is linked to a data point on the chart will still be shown, even if the data point itself is no longer being displayed.

Please note the following behaviour:

• Zoom settings will not transfer to the Average tab.
• Download marks and inspection marks will not be displayed in the "Average" tabs.
• Non-validated readings and re-calibrated readings will not be displayed with the special attributes, even if set in the options. If you have chosen to show non-validated readings, they are included in the minimum/maximum/average calculations, otherwise not.
• To avoid memory overflows, the maximum number of data points or loggers that can be shown in the average chart is restricted. If you try to show average charts outside these limits, you will see this warning message:
  

  Warning:Too many charts open

• If one or more of the charts have sections with readings outside the LogTag^®'s sensor range, LogTag^® Analyzer is unable to calculate the minimum, maximum and average values, and those sections of the graph will not be displayed. This will likely result in a "broken" graph line, regardless of whether show readings beyond specifications in the Charts section in the Options Window is enabled or not (Charts).
• Due to the large number of calculations performed in this feature, specifically when opening large numbers of charts spanning long periods, having the Average displayed can occupy large amounts of memory and run slow. Therefore we recommend only turning the feature on when required.

Clicking on the Average Icon in the toolbar again will turn the average display off. Selecting the single charts command in the toolbar will open each chart in the Multi-Chart in a separate File Window, however the Average Chart tab will not be closed.
