The TemporalPlotTool 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:TemporalPlotTool 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:Addtitleandlabelstoatimeseriesplot 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.
