 
wxGUI Temporal Plot Tool
The 
Temporal Plot Tool is a 
wxGUI
component that queries and plots the values of a point, defined by a coordinate
pair, in one or more temporal datasets (strds, stvds, str3ds).
Supported features:
  - temporal datasets with interval/point and absolute/relative time,
- show simple linear regression model line with calculated formula
    y = a + b*x (y is dependent variable, a is intercept, b is slope, x is explanatory variable) andr-squared (parameter of goodness-of-fit measure for linear regression model) 
- pop-up annotations with values information,
- query and plot multiple points via the command line,
- zoom and pan,
- change labels to x and y axes,
- add title to the plot, and
- 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 y = a + b*x because these software packages use a reference date other than
    the UNIX Epoch time (00:00:00 UTC on 1 January 1970)).

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 
Draw as
showed below.

To export the time series data to a text file (date and data values), type a
name for the file and click 
Draw again. Optionally, set the
check-box to print headers, as well.
