Drawing Graphs in GH2

One of the more conspicuous ways in which working in Grasshopper differs from working in -say- Visual Studio, is that it is trivial to tweak values by hand at runtime. If one wishes to provide control over some constant used in a C# algorithm, one must either build a UI with buttons, sliders, checkboxes and whatnot, or maintain a live link to a settings file which can then be modified using notepad. The first approach requires a fair amount of work on the part of the developer, the latter is supremely user-unfriendly.

Although we collect no data on this, I would not be surprised in the least to find out that the most commonly used object in all Grasshopper files ever is the number slider. Numbers are almost always one of the required inputs of any given algorithm, and the slider provides an easy way to interactively adjust them. I do not think the implementation of sliders in Grasshopper 1.0 is perfect, but at least access to numeric constants works far better than the way in which GH1 provides access to equations. The Graph Mapper object is probably the most commonly used worst piece of UI garbage in the history of Grasshopper.

Science!
