wxGUI Temporal Plot Tool

DESCRIPTION

       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)
               and
               r-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)).
       Figure:  Temporal Plot Tool 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.
       Figure: Add title and labels to a time series plot 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.

NOTES

       g.gui.tplot requires the Python plotting library Matplotlib.
