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.
