How To Create A Statistical Graph

Create a Statistical Graph

To create a statistical graph:

1. Select the data table on which you want to base the graph. A graph can be based on either link or node data. Alternatively, if you already have a graph open, you can select that graph and base the new graph on the selected graph.
2. From the Graphs menu, select the type of graph that you want to create.
3. Select the data variables to be used to create the graph. The information that you provide varies with the type of graph, as described in the following table:

   Bar chart	Select the category variable (X axis) from the Category list box. Only character data type variables are available. The default selection is the first variable in the data table. Select the measure variable (Y axis) from the Response list box. Only numeric data type variables are available. If you choose the default selection <Frequency>, then the application displays a frequency chart for the Category variable. (Optional) If you want the bar chart to have an additional subgroup category, then select the variable from the Subgroup list box. Numeric and character data type variables are available. The default selection is <None>.
   Box plot	Select the category variable (X axis) from the Category list box. Only character data type variables are available. The default selection is the first variable in the data table. Select the measure variable (Y axis) from the Response list box. Only numeric data type variables are available.
   Histogram	Select the X variable for the histogram from the X Variable list box. Only numeric data type variables are available. The default selection is the first numeric variable in the data table. Select the Y variable for the histogram from the Y Variable list box. Only numeric data type variables are available. If you choose the default selection <Frequency>, then the application displays a frequency histogram for the X variable.
   Pie chart	Select the category variable from the Category list box. Numeric and character data type variables are available. The default selection is the first variable in the data table.
   Scatter plot	Select the X variable for the plot from the X Variable list box. Only numeric data type variables are available. The default selection is the first numeric variable in the data table. Select the Y variable for the plot from the Y Variable list box. Only numeric data type variables are available. (Optional) Select the Z variable for the plot from the Z Variable list box. Only numeric data type variables are available. The default selection is <None>.
