Set the drawing mode of a 16-Pen Trend

You can select the line drawing mode of a 16-Pen Trend based on the value of the 16PenTrendDrawMode parameter.

• Averaging mode: 16PenTrendDrawMode=0

  Because of the time range and the buffer size of the 16-Pen Trend, each pixel on the trend can represent several seconds' worth of data. Each interval can contain several samples with different values. As a result, the trend’s data point can appear as a vertical line between the maximum and the minimum values observed within the interval.

  After the minimum to maximum vertical line is drawn, the trend pen moves to the calculated average value for the interval. The next interval begins by drawing the line from the average value to the next interval on the trend. The vertical minimum to maximum line is drawn and the pen rests at the average value calculated for the interval. This process repeats for each sampling interval.

  Averaging is the default drawing mode of a 16-Pen Trend if the 16PenTrendDrawMode is not specified in the INTOUCH.ini file.

• Min-Max mode: 16PenTrendDrawMode=1

  In the Min-Max drawing mode the trend line is drawn by directly connecting the endpoints of each data collection interval.
