Trend Charts

SpecView supports the use of many trend charts simultaneously.

There is no limit to the number of screens that can have trend charts on.

Any screen may have one or more trend charts on it, subject to space.

Trend charts can have any time-span from 1 minute to 1 month, and different charts may have different spans on a single screen (this is useful for having a long-period chart showing overall trend and a short period chart showing very recent activity in detail.

Trend charts can have as many pens as you wish, however, the differences in color make it impractical to have more than about 10 on any one chart at the same time.

Trend charts can replay data in Historical Replay allowing the easy review of past data.
