💫 wxGUI Interactive Scatter Plot Tool 💫

okay bestie, come sit with me, we're reading wxGUI.iscatt(1grass) — yes that's the whole manual name, no I will not be shortening it, it's giving full government name energy 💅

🔑 KEYWORDS 🔑

display, GUI, imagery, scatterplot, plot

✨ DESCRIPTION ✨

The Interactive Scatter Plot Tool is your new obsession for analyzing a group of raster maps. It's built right into the Supervised Classification Tool (peep the screenshot below, it's serving). You can also launch it from the Map Display Window via Analyze map → Interactive Scatter Plot Tool — like, two ways in, we love options.

The whole ✨ main character concept ✨ here is that everything is linked together — the scatter plots linked to each other, and the map window linked to all the scatter plots. And the headline feature? Interactivity. Which means you, yes you, get to:

• work with multiple plots, each one representing multiple raster bands combinations 🎀
• highlight plotted points in the open scatter plots based on the pixels currently chosen for classes by its training areas — lowkey only supported in the Supervised Classification Tool, so iykyk
• define areas in plots, and the tool will highlight the pixels in the map display window and the corresponding points in the other plots 🦋
• plot of confidence ellipses — fancy, iconic, no cap

🎛️ TOOL CONTROLS LAYOUT 🎛️

If editing mode is activated (that's the green polygon tool in the toolbar, bestie), the areas you selected in the scatter plots get highlighted. In the image you can see this area for a scatter plot of bands B_6, B_7 sitting inside the ellipse. The opacity and color of the selected area can be set in settings. That area corresponds to the active class (in this case, clouds ☁️). Selected areas are a subset of areas, which belongs to the category.

While you're in editing mode, you can select a certain area using the polygon, which can be created and edited with the tools in the editing toolbar. Once the area is selected, you can include or exclude it into the active category by clicking the first (plus) respectively second (minus) tool in the editing toolbar. In the mapwindow, the corresponding pixels are shown by the class raster representing the selected areas in the scatter plots. In this case we can see the clouds class raster (blue 🩵), the forest class raster (green 💚) and the water class raster (red ❤️).

📝 NOTES 📝

• The tool can analyze only integer (CELL) rasters.
• It works with 8 bit range smoothly. 🧈
• It can process data up to 12 bit range, but fr fr, it is not recommended to open many scatter plots in 12/11 bit mode — it could require a significant amount of memory and plot rendering time can be longer. 😭
• Analyzing raster data with a higher range is not recommended.
• The raster range can be lowered using r.rescale. 🫶

💀 KNOWN ISSUES 💀

Selection of areas in the mapwindow is currently supported only if the tool was launched from the Supervised Classification Tool. That's it, that's the whole vibe check. 🙈

and that's the whole page, periodt 💖 this was rendered off the GRASS 8.5.0 Reference Manual, © 2003-2026 GRASS Development Team, and the man page we just devoured was wxGUI.iscatt(1grass) from GRASS 8.5.0 ✨ thanks for scrolling with me, mwah 🎀🦋
