How to draw a double bar graph on height amd weight

first what you have to do is to buy a bar graph.
second now you have to draw the x-axis and y- axis on the graph paper.
third you have to draw the bars of uniform length and uniform size.
for example you have drawn five bar graphs.
for example the observations are the marks scored by a is eng-70, french-50 and science-90.
and b has scored the marks eng-80,french-90
 and science 100.
so there are three observaions.
so you will draw 1 bar graph and from the same bar graph you will draw the other bar graph adjacent to it.
hope this helps else you can refer the study in meritnation maths.
