Draw a pie-diagram for the following data of the investment pattern in a five year plan:
|Agriculture||Irrigation and Power||Small Industries||Transport||Social service||Miscellaneous|
Central angle of a component = (component value/sum of component values x 360)
Here the total percentage = 100%
Thus, the central angle for each component can be calculated as follows:
|Agriculture||14||14/100 x 360 = 50.4|
|Irrigation and Power||16||16/100 x 360 = 57.6|
|Small Industries||29||29/100 x 360 = 104.4|
|Transport||17||17/100 x 360 = 61.2|
|Social Service||16||16/100 x 360 = 57.6|
|Miscellaneous||8||8/100 x 360 = 28.8|
Now, the pie chat representing the given data can be constructed by following the steps below:
Step 1 : Draw circle of an appropriate radius.
Step 2 : Draw a vertical radius of the circle drawn in step 1.
Step 3 : Choose the largest central angle. Here the largest central angle is 104.4o. Draw a sector with the central angle 104.4o in such a way that one of its radii coincides with the radius drawn in step 2 and another radius is in its counter clockwise direction.
Step 4 : Construct the other sectors representing the other items in the clockwise sense in descending order of magnitudes of their central angles.
Step 5 : Shade the sectors with different colours and label them as shown in the figure below.
