What happens if there are more data points to draw than pixels available to draw them on an Axiom trend graph?

Axiom can use to different drawing modes to represent data. These two drawing modes include weighted TimeAverage and High/Low.

By default, Axiom draws data in weighted TimeAverage mode (learn how to adjust this default). This means if there are more values to display than there are pixels, the average of the values will be drawn. 

Often clients need to see a different representation of the data and will switch to a High/Low drawing format. This option will not draw in a weighted time average format but will instead draw both the highest and lowest value within the set.

Below is an example of both drawing styles for a point that changes every second with a chart duration of 8 hours (28,800 values).

The red pen represents the weighted TimeAverage and the blue pen represents the High/Low drawing style. On closer examination of part of the period, you can clearly see the difference.

To switch between these drawing styles, do the following:
