Procedure Step1 Look at the data in TABLE1 . It has two sets of data: average monthly precipitation and average monthly temperature. TABLE1 New Delhi, India, 28 ° N77 ° E, average monthly precipitation and average monthly temperature Jan. Feb. Mar. Apr. May Jun. Jul. Aug. Sep. Oct. Nov. Dec. ° C 14.1 16.9 22.4 28.6 32.8 33.8 31.0 29.8 29.2 26.0 20.3 15.4 mm 22.7 20.1 14.5 10.1 15.0 67.9 200.4 200.3 122.5 18.5 3.0 10.0

Step2 Consider the range of the data before you decide what scales will work for the vertical axes. For the right axis, ýnd the wettest month. The precipitation scale begins at 0 and must extend far enough to include the wettest month. For the left axis, ýnd the highest and lowest temperatures. A scale of 0 ° C to40 ° Cwill suit most climate graphs. Try to use temperature and precipitation scales that prevent the line and column graphs from overlapping. This may not be possible if the place has very high rainfall. Step3 Use a ruler and pencil to draw the axes on graph paper. Divide the horizontal axis into 12 equal sections to represent the months of the year. Label each month with its initial. Label the temperatures on the left vertical axis and precipitation on the right vertical axis.
