Trend Graphs now standard in ImageFlow

Trend Graphs can be useful for process control

Trend Graphs in Imageflow allows real-time display of metrics that can be used to monitor a key measurement or quality index for a complete run. The graph below shows the web width and total number of defects plotted versus the machine direction of a job.
