This project graphs a scatterplot with random values that are correlated (like in the real world). You can adjust the settings and the graph will change. The higher the correlation value, the closer each x, y pair will be. Negative correlation means y decreases as x increases. To get a new graph, press <space>. Pressing <right arrow> will change the scale of the graph (1, 10, or 100).
I created this to be able to procedurally generate appel levels with correlated parameters. To use correlated "randomness" in your projects, simply backpack the custom block called "correlate x and y" (I would very much appreciate credit if anyone uses this.)
