The horizontal and vertial line in a graph are called axes.

See the bar for tomatoes. How far upwards does it go? Try and connect it with the number on the vertical axis by drawing a straight line from its top to the vertical axis exactly parallel to the horizontal axis.

Which is the smallest and the biggest percentage of students?

Think: In how many parts do the axes divide the graph?

Let us try to plot the point.

We always start with the number 1 and move anti clock wise.

Is there any interval, over which, you are measuring the bar graphs?

By how much is the upper limit of the frequency increasing every time on the vertical axis?

Try and imagine to divide the interval from 100 to 200 in quarters.

Moving across to the right? On what axis are we moving.
