Here, we take years on the x-axis and the number of patients on the y-axis.
Let us choose the following scale:On x - axis: 1 cm = 1 year On y - axis: 1 cm = 10 patients
Now, let us plot (2002, 150), (2003, 170), (2004, 195), (2005, 225), (2006, 230). These points are joined to get the graph representing the given information as shown in the figure below.
Scale:
On x axis: 1 cm = 1 year
On y - axis: 1 cm = 10 patients
