Graph > Scatterplot Graph > Scatterplot A scatterplot shows a collection of points on an x-y plane in cartesian coordinates. The scatterplot graph utility allows the user to specify a number of series, each of which has a collection of (x, y) points specified by a x column variable and y column variable. It also provides the options of having a plot title, axis labels, legend, and regression lines. To open the scatterplot utility, select Graph > Scatterplot. To add a series of (x, y) points to the plot, select the column variable containing the x coordinates in the X variable drop-down menu, select the column variable containing the y coordinates in the Y variable drop-down menu, and then click the Add Series button. The added series will be shown in the Graph X,Y Series list. The x and y column variables must have the same number of items. To remove a series from the Graph X,Y Series list, select the item and click the Remove Series button. Enter labels for the x and y axis in the corresponding text fields. Enter the plot title in the Plot Title: text field. Select the Show Legend check box to show a legend indicating the different series. Select the Show regression curve check box to show a regression curve for each data series. Choose the desired regression model, linear or non-linear. Click OK to create the scatterplot.
