Drawing shapes
The Plots package exports the Shape type to construct polygons. This section will teach us how to use it to create custom shapes with Plots. This will be helpful when drawing or while creating novel plotting types. We can also take advantage of Shape to design custom markers. The Shape constructor takes the vertices coordinates of the desired polygon. We can pass them in two different ways:
- We can give a vector for each axis containing the vertex coordinates for that dimension. For example, we can call
Shape(x, y)if thexandyvariables are vectors of numbers of the same length. This is one of the ways we usually call theplotfunction; that is,plot(x, y). - We can give a single vector containing a tuple of numbers, with each tuple containing a vertex’s (x, y) coordinates. Interestingly, we can also call
plotor other plotting functions such asscatterwith that input. For example,plot([1, 2, 3], [6, 7, 5])andplot([(1, 6), (2, 7), (3, 5)])are...
