BAR GRAPHS
The information on a tally chart can also be represented on a bar graph.
Bar graphs are very useful as it gives you a visual representation of data. It allows you to compare data collected. It is quite easy to construct your own bar graph. Below show a bar graph showing a title (My Savings), the labels along the graph showing what the data is about, the scale showing the numbering, and the bars that shows the height.
