1) Unblankedmcr is an add-on that is only called from a macro command. It has two functions:

• COMMAND='CountUnblankedDataPoints' creates the frame auxiliary data 'NumberUnblankedNodes' that is the number of data points that are displayed in the current frame. It means it respects zone activity and value-blanking. It works in XY, 2D and 3D modes.
  You can then use this number as a dynamic text in your frame.
• COMMAND='CopyUnblankedDataPointsToNewZone' creates a new zone called 'Compilation' that contains all the data points that are displayed in the current frame. Only the points are compiled: any geometry is lost in the operation. It works in XY, 2D and 3D modes.

Hint: If you need a GUI for this add-on, call it from the quick macro-panel

2) List of changes in the Data Selector add-on:

• The maximum number of data points has been increased to 2 million points
• The add-on works now in 2D mode with an X/Y ratio non-equal to 1
• New feature: Calculates the sum for each variable for all selected points
• New feature: Calculates the mean for each variable for all selected points
