Climographs combine bar graphs and trend graphs to show two different sets of data on one chart. Sometimes each side has a different scale, e.g. in Figs. 18 and 19, temperature is shown in degrees Celsius on the left-hand scale and rainfall is shown in millimetres on the right-hand side. The bars indicate the level of rainfall and the lines indicate temperature.
