Disadvantages of Scatter Charts Can Have Too Much Data The maximum and minimum values can be seen on scatter plots, which is important to understand the entire data set. Not only that, but for those wanting to make a scatter chart, they are simple to create. Their purpose is easily recognized, and its data is easy to digest. Perhaps because of its popularity, scatter plots are immediately understood. Not only does it show a relationship between two data points, it shows a whole pattern or trend over a data set. This is arguably the best chart to show relationships between two variables. Scatter charts have multiple benefits and advantages. Does the weather influence sales? The day of the week? What about the number of clothes on a rack? Are more clothes sold if there are more on display? Benefits of Scatter Charts While this simple scatter chart may not drill down and show all the variables, such as location, the recentness of renovations, or size of the garden, it will still give buyers and sellers an idea of what the market is doing and where a house may fit on the scale.Ī business may want to see if there is a relationship between sales volumes and some other variable. To see a correlation, pattern, trend, or relationshipĪ real estate agent may want to see a relationship between square footage and the price paid for homes.To see how one variable affects another.When to Use Scatter ChartsĪside from scientific studies, there are a few times when businesses may decide to use a scatter chart: However, do not have more than two trend lines, as this can be confusing. These lines help to make trends very clear to the viewer. These lines are generally plotted by the software, although they can be added manually. Consider adding size and color variations to dots in order to include more relevant data in a way that keeps it easily understood. Unlike other chart types, if done correctly, scatter charts are not confusing with more data. With scatter plots, it is often better to include more data and variables, not less. If there is reason to suspect they are incorrect, or if they do not add value to your story, it could be wise to exclude them. Keep the scale evenly distributed across both axes. Be very careful when deciding if an accordion is needed or not. While there may be some instances where a scale accordion is required so that the data is presented more accurately, these instances are few. There are a few simple tips to make sure your scatter chart presents information cleanly and without any distortion to the data. A trend line is drawn on the chart to emphasize the direction and strength of the trend. In order to clearly show these relationships and trends, many scatter charts utilize trend lines. A weak correlation will have more data points spread out. Weak or strong: The stronger the correlation is, the closer the dots will be together.Linear or nonlinear: A linear-straight-correlation can be formed through the data points, but a non-linear correlation might show a curved relationship.There are other patterns to be found within a scatter chart: An even scale is created on both axes, and then a mark or dot is made at the point that represents the intersection of the two coordinates. The X is the horizontal line with the independent variable and the Y is the vertical with the dependent variable. Like most other graph or chart types, a scatterplot has an X and a Y axis.
