The Time Plot (
)
is intended for plotting time series data.
The horizontal axis represents time, and can be labelled accordingly (for instance in minutes, hours, days, months and years), and the window can display appropriate types of plot including spectrograms.
To define the time coordinate, use the Time selector in position tabs as usual. Note however that this contains a time format selector on the right hand side that indicates how the selected quantity will be interpreted as a time value. The options are:
).
Unlike the other plot windows (at time of writing) the Time plot can display different data plots in different plot Zones stacked vertically on top of each other, so that different plots share a time axis but have their own Y axis. Note: This multi-zone feature is somewhat experimental, and the user interface may change in future versions.
The Time Plot offers the following plot controls:
Position Layer Control, with these form options:
Line
Linear Fit
Mark
Error Bars (vertical bars only)
Label
Fill
Quantile
Grid
Histogram Layer Control with these form options:
Note that some of these histogram-like controls offer the
Combine option that lets you define how values
are combined together.
If you choose the sum-per-unit
or count-per-unit
options, you can also use the Per Unit selector
to determine whether values are represented as sums/counts per
second, hour, day, year, etc.
Spectrogram Layer Control
Function Layer Control
As well as the standard actions, this window additionally provides the following toolbar button:
See the Window Overview for features common to all plotting windows. The following subsections describe zones, navigation and axis configuration.
