wxGUI Temporal Plot Tool

DESCRIPTION

7       The  Temporal Plot Tool is a wxGUI component that queries and plots the
8       values of a point, defined by a coordinate pair, in one or more  tempo‐
9       ral datasets (strds, stvds, str3ds).
10
11       Supported features:
12
13           •   temporal  datasets  with  interval/point  and absolute/relative
14               time,
15
16           •   show simple linear regression model line with  calculated  for‐
17               mula
18               y = a + b*x (y is dependent variable, a is intercept, b is slope, x is explanatory variable)
19               and
20               r-squared (parameter of goodness-of-fit measure for linear regression model)
21
22           •   pop-up annotations with values information,
23
24           •   query and plot multiple points via the command line,
25
26           •   zoom and pan,
27
28           •   change labels to x and y axes,
29
30           •   add title to the plot, and
31
32           •   export  the  time  series values to a CSV file (x axis data has
33               date time string format, if you want  to  use  for  calculating
34               simple regression model in the R environment, LibreOffice etc.,
35               you will obtain a different calculated formula
36               y = a + b*x
37               because these software packages use a reference date other than
38               the UNIX Epoch time (00:00:00 UTC on 1 January 1970)).
39       Figure:  Temporal  Plot  Tool To optionally add a title to the temporal
40       plot and/or change the x and y axes labels, first type the desired text
41       and then click Draw as showed below.
42       Figure:  Add  title and labels to a time series plot To export the time
43       series data to a text file (date and data values), type a name for  the
44       file and click Draw again. Optionally, set the check-box to print head‐
45       ers, as well.

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