**Types of Graphs**What guidelines should we follow in choosing a type of graph?**Use a Bar Graph to show comparisons and data that can be**counted.**Use a Double Line Graph to show data comparing 2 groups that**change over time.**Use a Pictograph to show comparisons and data that can be**counted if it involves multiples of a number.**Use a Histogram to show how often something happens and when**using equal intervals. The bars do not have spaces between them.**Number of books checked out each month from the library.A.**histogramB. pictographC. double line graph**The height of two trees over 5 years.A. Bar graphB.
