Talking about seconds, minutes, hours, days, years, etc. Units as well as the numeric values so people will know if you are If you are measuring time, you must include the Label might read 'Total Rainfall' and the x-axis label might read Indicating which variable is represented. When graphs are compared side-by-side, consider scaling them to the same data range to make comparisons easier. Typically the scale runs from low to high inĮasily counted multiples like 10s, 50s, 100s, etc. The scale is measured off in major and minor The highĮnd of the scale is usually a round number value slightly larger than Number value slightly smaller than the smallest data point. The low end of the scale may be zero or a round Graphs with only positive values for x and y, the origin is in theĮach axis needs a scale to show the range of theĭata on that axis.

Referred to as the origin, where the coordinates are (0,0). (horizontal line) of the graph and the dependent variable belongs on The independent variable belongs on the x-axis Graph inches of rainfall in 20 against time of For example, you may overlap plots of rainfall in theĭesert and rainfall in the tropics against time of year, or you could Than one dependent variable, but never more than one independent Therefore, rainfall is the dependent variable and time of year On time of year, but time of year does not depend on rainfall. Of rainfall that occurs at different times of year. Imagine that we want to make a graph of the amount
