Heatmap Plot

Use this to specify data for a heatmap plot. This uses the DHEATMAP procedure which displays the values of a data variate as a colour spectrum, plotted spatially in a grid defined by x and y values. There must be just one occurrence of each combination of the x and y values in the data, but the x-y grid does not have to be complete. After you have selected the data, you can draw the graph by clicking Run. You can set additional options by clicking the Options, Key, X Axis, Y Axis and Frame tabs.

Available data

This lists data structures appropriate to the current input field. It lists either variates, factors or texts for specifying the data. The contents will change as you move from one field to the next. Double-click a name to copy it to the current input field or type the name.

Data to plot as a colour

Specifies the variate to be plotted as colours. The values are converted to colours using the FHEATCOLOURS procedure. Double-click a name in the Available data field to copy it across or type the name. You can also use the button to move a selected item to the field.

Y values

Specifies the y-coordinates (a variate or factor) of the cells to be plotted in a grid. Double-click a name in the Available data field to copy it across or type the name. You can also use the button to move a selected item to the field.

X values

Specifies the x-coordinates (a variate or factor) of the cells to be plotted in a grid. Double-click a name in the Available data field to copy it across or type the name. You can also use the button to move a selected item to the field.

Labels

Specifies optional labels to be plotted within the cells defined by the x and y values. A text, variate or factor can be used to specify the labels. Double-click a name in the Available data field to copy it across or type the name. You can also use the button to move a selected item to the field.
