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)).

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.

g.gui.tplot add title and axes labels

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.
