Scatterplot symbol from another variable

jrleighty — Wed, 29 May 2024 19:48:24 GMT

I have a dataset with five variables I would like to use to display the data on a graph. The data is grouped by the first variable (p) and sub-grouped by the second variable (i) along the x-axis. The fourth variable (nor) determines the height of the point along the y-axis. The fifth variable (mnor) is the mean of the nor values for each subgroup.

I want to replace the circle with a unique symbol determined by the third variable (date), so that the graph is easier to interpret the results from different days the data was collected. I have been able to replace the point with the date but would prefer a symbol to minimize clutter. I've included a sample code below. The first graph is my original graph without including the date variable, and the second graph is replacing the points with the date value.

data samp;
	input p$ i date: date9. nor mnor;
	format date date9.;
	datalines;
	A 0 16May2024 1.230 1.000
	A 0 23May2024 0.770 1.000
	A 1 16May2024 0.014 0.021
	A 1 23May2024 0.028 0.021
	B 0 16May2024 1.576 1.504
	B 0 23May2024 1.432 1.504
	B 1 16May2024 0.064 0.071
	B 1 23May2024 0.078 0.071
	C 0 16May2024 0.432 0.510
	C 0 23May2024 0.588 0.510
	C 1 16May2024 0.011 0.009
	C 1 23May2024 0.007 0.009
	;

title "Example Graph 1";
proc sgplot data = samp noborder;
	scatter x = p y = nor /
		markerattrs = (symbol=CircleFilled) group = i  groupdisplay = cluster;
	highlow x = p low = mnor high = mnor / nofill type = bar barwidth = 0.4 group = i groupdisplay = cluster;
	xaxis type = discrete labelattrs = (size = 9) display = (nolabel);
	yaxis labelattrs = (size = 9) display = (nolabel) grid;
run;

title "Example Graph 2";
proc sgplot data = samp noborder;
	scatter x = p y = nor /
		markercharattrs = (weight = bold) markerchar = date group = i groupdisplay = cluster;
	highlow x = p low = mnor high = mnor / nofill type = bar barwidth = 0.4 group = i groupdisplay = cluster;
	xaxis type = discrete labelattrs = (size = 9) display = (nolabel);
	yaxis labelattrs = (size = 9) display = (nolabel) grid;
run;

Can you post a link to a graph similar to what you want?

Does your "real" data have more than 2 dates involved?

I am having a hard time envisioning, given the data, the use at all. You have a highlow plot with the same variable for high and low which doesn't really make sense for the purpose behind high and low.

I cannot visualize what you are trying to do, but consider whether you need to use a second SCATTER statement to get the symbols that you need. The first SCATTER statement uses the GROUP= option, so the marker colors and symbols are tied to the group variable (i). You might need to structure the data differently and use a second scatter plot overlay to achieve your result.
