A broken axis graph is one in which part of the scale on the x or y axis has been omitted to save space. The broken axis graph has a wavy line at the location where the scale is broken.
Know MoreBroken scale graphs are useful in situations when the numbers near zero are not needed. For example, if one of the axes measures temperature during the summer months, it is unlikely that temperatures are below 20 degrees Celsius. In this case, breaking the axes serves to "zoom in" on the important data. Broken axes should only be used to make existing relationships more apparent. Broken axes should not be used to distort the nature of the data.
Learn more about Data GraphsGraphing x = 3 is a matter of drawing a vertical line on the Cartesian plane. For any equation x = n, where n is any real number, the resulting graph is a vertical line crossing the x-axis at the value of n. To graph the given equation, draw the Cartesian plane, plot the coordinates of the graph, and draw a line through it.
Full Answer >The first step in graphing an inequality is to draw the line that would be obtained, if the inequality is an equation with an equals sign. The next step is to shade half of the graph.
Full Answer >A picture graph is a visual method of displaying information that uses images or symbols to represent data. It includes a key or scale that indicates the value of each picture.
Full Answer >The primary advantage of using a graph or chart in a presentation is that they help the audience to visualize the point of the presentation. Graphs emphasize the main point, make the data more convincing, provide a compact way of presenting information and help audiences stay engaged. Disadvantages of graphs include being time consuming to construct and costly to produce. They also require technology that some may lack.
