wxGUI.tplot(1)

🌸 NAME 🌸

wxGUI.tplot — the Temporal Plot Tool, aka your new fave way to peek at what's happening inside your temporal datasets 💖

It lives in the GRASS GIS User's Manual, and honestly? It's giving main character energy.

✨ DESCRIPTION ✨

okay so bestie, the Temporal Plot Tool is a wxGUI component 🎀 and what it does is: it queries and plots the values of a point — a point defined by a coordinate pair, obviously — across one or more temporal datasets. And those datasets can be strds, stvds, or str3ds. All three. She's versatile like that 💅

Here's everything she can do, no cap:

• temporal datasets with interval/point and absolute/relative time ✨
• show a simple linear regression model line, with the calculated formula y = a + b*x (where y is the dependent variable, a is the intercept, b is the slope, and x is the explanatory variable), plus r-squared (the 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 🌟
• export the time series values to a CSV file — and heads up, the x axis data has date time string format, so if you want to use it for calculating a 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). Not a bug, just math being math 😭

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. Periodt. If you don't have it, she simply will not run, bestie 🙈
