SCATTER PLOT MATRIX HOW TO

The color of the dot tells what kind of vehicle (sedan, SUV, truck.) it is. Next, let’s highlight the cell range A2:B9, then click the Insert tab, then click the Scatter button within the Charts group.

SCATTER PLOT MATRIX HOW TO

Most high schools discuss how to interpret a scatter plot. So, it is possible to write a macro to draw a ' CompactMatrix' using the lattice layout, axis options and reference lines in GTL to create this graph. For the scatter plot matrix, you can see the doc for the SGSCATTER procedure. Another chart that is helpful here is to panel by jtype, which gives a stack of scatters by jtype. The grouped scatter picture is fairly clear, although I have trouble distinguishing all the groups. However, the id's really clutter this chart, so they are better omitted here. But how do we do this now?įor SAS 9.2 and SAS 9.3, the ScatterPlotMatrix both in GTL and SGSCATTER already use the LAYOUT LATTICE in GTL to create this graph.

Given that this arrangement is very popular, we will likely include an option to draw compact matrices in the next release based on the work shown here. Clinical concern levels are indicated by test case.Drawing of the upper triangle is eliminated resulting in a cleaner, uncluttered graph.The matrix occupies only a 3x3 grid for 4 variables hence uses the space more efficiently.All six pairwise combinations of the four variables are included in the graph.In fact, this arrangement is popular in the clinical domain as shown below in what can be called the 'Compact Matrix'. The first scatter plot in the leftmost column shows the relationship between Weight and Turning Circle. The scatter plots use the same colors and markers from Figures 9-11. Figure 14 shows a scatter plot matrix for the data on different models of cars. The upper triangle of the matrix is a mirror image of the lower triangle, and hence wasteful of the space.Ī closer examination of the graph indicates that we can eliminate the top row and right column of the matrix, to get a smaller 3x3 arrangement of the 4 variables, and still have all the pairwise scatterplot combinations for all the variables. The matrix can also identify outliers in multiple scatter plots.There is no way to indicate the clinical concern levels in the graphs.The matrix statement does not provide any way to customize the axes.There are a few issues with these graphs from a clinical perspective. A scatter plot matrix is a popular way of determining whether there is a linear correlation between multiple variables.
