Trend Logging

Plotting Data Using the Candlestick Format

When plotting the data for trend logging, the AMEVision software uses a
"candlestick" method to format the trending. This method allows more data
to be plotted than there is space available on your display giving you more in-
sight into how your analyzer is operating. It is also a useful tool for the techni-
cian who can see weeks and months of data to determine more easily at what
point a problem occurred or to use the data to head off a potential problem.
The candlestick method takes the minimum and maximum of each range of
sample data and produces a vertical yellow line – called a candlestick – to rep-
resent the sample range's minimum and maximum data sets.
