Master variables, speeds, levels, arrows and plot simulation data
Take population growth as an example:
Function setting: just
click the sidebar for drawing.
The key is:
Variables, only the storage of calculations are set, but the initial value cannot be set.
Level: Similar results, save the results, you can set the initial value.
Arrows: connect causality.
Velocity: Iterate the next level and variable in an additive manner.
