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. Figure: Export time series values to a text file
NOTES
g.gui.tplot requires the Python plotting library Matplotlib.
