Hi everyone!
I’m excited to share my new NetLogo project: ColorBar.
ColorBar is a NetLogo model demonstrating how to create a simple color bar plot. Since NetLogo does not include a built-in color bar widget, this model provides a workaround by drawing one using temporary plot pens.
A NetLogo extension may be developed in the future to simplify color bar creation. For now, this model serves as a practical example.
Click here to see this model online on NetLogo Web!
How It Works
The color bar can be drawn in any plot using the plot-color-bar procedure. This procedure takes the plot name as an argument and creates a random color bar with 10 different colors. The implementation can be adapted to fulfill specific requirements.
For another color bar implementation in NetLogo, see the LogoClim model.
