The legend can be used to make selections on the chart. The Pop out legend button displays the legend as a separate card on your page. To change the color associated with a value, click the symbol and choose a color from the palette or enter a hex value (available when a Color by variable is applied). The Legend tab displays the symbols and values on your chart. You can use the Layer options pane to view the legend, change the symbol type on the chart, and change the style of the chart. The Layer options button opens the Layer options pane. Scatter plots can also be created using View Scatter Plot, which is accessed by clicking the Action button under Find answers > How is it related. For the Visualization type menu, only compatible visualizations (including maps, charts, or tables) will be displayed. For the Chart menu, only charts that are compatible with your data selection will be enabled. You can also create charts using the Chart menu above the data pane or the Visualization type button on an existing card. To create a scatter plot, complete the following steps: The pattern shows that the highest concentration of colleges have a cost around $20,000 and result in earnings below $50,000. The analyst can change the style of the chart to Bins to see the distribution of the points on the scatter plot. The scatter plot shows a positive relationship, but the points are too densely distributed to see more specific patterns. The analyst starts their analysis by creating a scatter plot showing the cost of colleges and the average earnings after graduation. Visualize with binsĪ GIS analyst working for a consortium of colleges wants to find which states have high-value colleges. The scatter plot indicates that most of the pipe surveys occurred in April. Using the Color by option, you can style the points using unique colors for every unique value in the specified field. The public works department also wants to know whether there is any difference between pipes surveyed at different times of the year. A scatter plot with proportional symbols can be used to plot the total number of leaks versus the total length of pipes in each zone, with the size of the points representing the cost per day.ĭrag a number field to your page and drop it on your scatter plot to give your chart graduated symbols. The department also wants to know whether there is a relationship between the number of leaks or length of pipes and the cost per day (including construction, maintenance and repairs, and lost resources through leaks). The department wants to know how much of an effect the total length of pipes has on the number of leaks versus the impact of properties of the pipes, such as age or circumference. The R 2 value can be added to give a measure of the impact of the length of pipes on the number of leaks.Ī public works department has noticed an increase in leaks on water mains. Statistical models are illustrated with a straight or curved line, depending on your selected chart statistic. The scatter plot indicates that most of the pipe surveys occurred in April.Ī scatter plot can use regression analysis to estimate the strength and direction of the relationship between dependent and independent variables. Using the Color by option, the department can style the points using unique colors for every unique value in the specified field. A scatter plot can be used to plot the total number of leaks versus the total length of pipes in each zone. The department wants to know how much of an effect the total length of pipes has on the number of leaks compared to the impact of properties of the pipes, such as age or circumference. Two variablesĪ public works department has noticed an increase in leaks on water mains. The examples below show scatter plots using two variables, three variables, and bins. Scatter plots can answer questions about your data such as, What is the relationship between two variables? How is the data distributed? Where are the outliers? Examples The x-axis represents the independent variable, and the y-axis represents the dependent variable. Scatter plots are used to determine the strength of a relationship between two numeric variables.
