Change to a Stairstep Chart

An advantage of the YearlyRainfall class design is the flexibility to modify the type of

graph used without making previously saved objects incompatible. Loading the object

recreates the graph based only on the data that is saved to the MAT-file.

For example, change the type of graph from a bar chart to a stair-step graph by modifying

the setup method:

methods(Access = private)

function setup(rf,data)

rf.Chart = stairs(data);

end

end
