A traversing vector is a vector that is generated by 2 signals: a position signal and a value signal, for example from a traversing measuring device.

The traversing vector is supported in ibaQPanel in the following displays:

• time and lengthbased trend graph

• timebased HD trend graph

• time and lengthbased offline trend graph

• offline trend graph with length conversion.

The function is not available in the lengthbased HD trend graph.

Note
	For both trend graphs and HD trend graphs, only the data from the signal buffer is used for display. Data from the past is therefore only available to a very limited extent.

If there are 2 signals in a trend graph (or any other of the above displays), the Convert signals into a traversing vector command appears in the context menu.

When you select this command, the dialog appears where you can set the properties of the traversing vector.

You can give the vector a name. Assign the corresponding signals to the value and position signal.

Define the number of zones you want to generate. You can also define the range of the position signal that will be divided into zones.

Example:

In the example 5 zones will be generated between Min and Max. The first and the last zones have half the width of the other zones. The zone width is calculated as (Max - Min) / (Number of zones - 1). The zones are positioned like this:

Z0 = from Min to Min + ZoneWidth/2

Z1 = from M1 - ZoneWidth/2 to M1 + ZoneWidth/2 with M1 = Min + ZoneWidth

Z2 = from M2 - ZoneWidth/2 to M2 + ZoneWidth/2 with M2 = Min + ZoneWidth*2

Z3 = from M3 - ZoneWidth/2 to M3 + ZoneWidth/2 with M3 = Min + ZoneWidth*3

Z4 = from Max - ZoneWidth/2 to Max

As long as the position signal is within a zone the values of the value signal are averaged. When the position signal leaves a zone the averaged value is saved at the middle of the zone. When the position signal is less than Min or greater than Max the values are ignored and no new zone data is created.

If you enable the "Use interpolation" option, the data will be interpolated in both X and Y directions. In order to do the interpolation we need 2 values so a zone can only be painted when a new point arrives. That is why in interpolated mode a jagged edge is displayed according to the traverse path of the traversing probe.

Without interpolation the value only changes when a new value arrives and otherwise the value is the last one. So the display must not wait for the next value and a straight line can be painted.

The reset signal is optional. When the reset signal is TRUE the position signal is ignored. When the reset signal is FALSE again new zone data is generated but it will not be connected to the previous zone data.

The length resolution refers to the resolution of the position signal.
