![]() This defeats the purpose of a chart, which is to simplify complex data.Ī scatter plot of the same data, on the other hand, would look like this:Ī clear inverse relationship is shown between both variables on the above scatter plot. If you’re trying to establish correlation between the two variables, it is difficult to determine a pattern.We cannot clearly see the disparity between the temperature on March 14 (2.5 degrees Celsius) and the one on March 20 (16.2 degrees Celsius). ![]() Since the numbers being used to measure each variable are so far apart, it is difficult to see the changes and fluctuations to the numbers which carry a smaller value (Daily Temp).Two limitations of the above line chart are: The following shows the result of creating a line chart when a scatter graph should have been plotted instead. Let us suppose that we had the following worksheet data: A scatter chart never displays categories on the horizontal axis, while a line chart does.A line chart only has one numerical axis (the vertical, or Y, axis). The chart plots the intersection of X and Y numerical values into single data points (see below). A scatter plot always has numerical data on both axes, with the objective of determining a relationship between the two variables.A scatter plot is more about the relationship between the two variables, while a line chart places more emphasis on the values attached to those variables.You can tell the difference between these two chart types in the following ways: A few key differences are described below.ĭifferences between a scatter plot and a line chart However, scatter plots and line graphs are not the same. When a scatter plot is generated with connecting lines, one may make the mistake of thinking that it is a line graph. Some scatter plots even have a trendline to make any pattern more evident. If the points on the plot appear randomly, the two variables are interpreted as having no correlation. ![]()
