Please explain.what is the method to interpret such graphs?

To interpret any graph the first thing to note is the quantity which is to be determined.
In this case charge is to be determined.
The second thing to note is the axes. Here I and t form the y and x-axis, respectively.
Now, see the relation between the given and to be found quantities. In this case Q = It
So, basically we will find charge by multiplying current and time. So, we multiply x and y-axes quantities.
Now, multiplying both axes means finding the area under the graph.
So, the charge in each interval is
Q1 = 2 × (2 - 1) = 2 C
Q2 = 1 × (5 - 3) = 1 × 2 = 2 C
Q3 = ½ b × h = ½ (8 - 6) × 2 = 2 C
Hence, the ratio is 2 : 2 : 2 = 1 : 1 : 1
