# wxGUI.tplot(1grass)

## 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.\

## NOTES

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