.SH wxGUI Temporal Plot Tool
.SH DESCRIPTION
The \fBTemporal Plot Tool\fR is a \fIwxGUI\fR
component that queries and plots the values of a point, defined by a coordinate
pair, in one or more temporal datasets (strds, stvds, str3ds).
.PP
Supported features:
.RS 4n
.IP \(bu 4n
temporal datasets with interval/point and absolute/relative time,
.IP \(bu 4n
show simple linear regression model line with calculated formula
.br
.nf
\fC
y = a + b*x (y is dependent variable, a is intercept, b is slope, x is explanatory variable)
\fR
.fi
and
.br
.nf
\fC
r\-squared (parameter of goodness\-of\-fit measure for linear regression model)
\fR
.fi
.IP \(bu 4n
pop\-up annotations with values information,
.IP \(bu 4n
query and plot multiple points via the command line,
.IP \(bu 4n
zoom and pan,
.IP \(bu 4n
change labels to x and y axes,
.IP \(bu 4n
add title to the plot, and
.IP \(bu 4n
export the time series values to a CSV file (x axis data has date time string format,
if you want to use for calculating simple regression model in the
R environment,
LibreOffice
etc., you will obtain a different calculated formula
.br
.nf
\fC
y = a + b*x
\fR
.fi
because these software packages use a reference date other than
the UNIX Epoch time (00:00:00 UTC on 1 January 1970)).

\fIFigure: Temporal Plot Tool\fR
To optionally add a title to the temporal plot and/or change the x and y
axes labels, first type the desired text and then click \fIDraw\fR as
showed below.
.br
\fIFigure: Add title and labels to a time series plot\fR
To export the time series data to a text file (date and data values), type a
name for the file and click \fIDraw\fR again. Optionally, set the
check\-box to print headers, as well.

\fIg.gui.tplot\fR requires the Python plotting library
Matplotlib.
