To change the color of the trend line, click the trend line color swatch in the Chart Properties pane and choose a new color. To turn off the trend line, uncheck the Show linear trend check box in the Chart Properties pane, or turn visibility on and off by clicking the item in the legend. This is only relevant for linear relationships. The trend line models the linear relationship between x and y, and the R² value quantifies how well the data fits the model. StatisticsĪ regression equation is calculated and the associated trend line and R² value are plotted on scatter plots. Additionally, a third numeric variable can be specified to proportionally size each point in the plot. Scatter plots are made up of two numbers, one for the x-axis and one for the y-axis. Checking the Show preview chart check box allows you to dynamically explore each mini chart in greater detail by selecting one to view in the larger preview chart.

For instance, setting Mini charts per row chart to 3 will display a maximum of three charts per row-the total number of rows in the grid will be determined by the number of series in your chart. You can customize the dimensions of a grid chart layout by setting the Mini charts per row numeric input. Grid charts are helpful for comparing trends and patterns between different subgroups in your data. This option displays a matrix of smaller charts, where each mini chart only shows data for an individual series. You can also view a scatter plot with multiple series as a grid chart (also known as small multiples) by selecting the Grid option. In this representation, all series are drawn in the same plot area, but each series is assigned a unique color to allow comparisons between the different groups. By default, multiple series are displayed with the Single chart option. To configure a scatter plot with multiple series, use the Display multiple series as option under the Series tab in the Chart Properties pane. The Series table will populate with each unique crime type ( Theft, Vandalism, Arson), and the resulting chart will display three scatter plot series.
For example, in a dataset of crime incidents, a CrimeType field can be used to split the data into multiple series. Scatter plots can be displayed with multiple series by setting a Split by category field. When the resulting points form a nonrandom structure, a relationship exists between the two variables. For each record, a point is plotted where the two variables intersect in the chart. Scatter plots visualize the relationship between two numeric variables, where one variable is displayed on the x-axis, and the other variable is displayed on the y-axis.
