How to plot shade red according to ratio variable using sgpanel plot - sas

Question

I would like to plot dataset and obtain desired output with the right setup.
Plot the scatter such that the points are in shade red-color, from light red to dark red depending on the scale (ratio) of 0-1 (0=light red, 1=dark red).
Show the legend also showing the scale red color according to the ration 0-1 (point 1.)
Data explanation:
area - city (shortcut)
id - user id
var - variable
time - datetime
exit - consumer left
ratio - proportion (between 0-1)
Data sample and attempt plotting (obviously not correct):
data data;
input area $ id $ var $ time $ exit $ ratio $;
datalines;

Answer 1

This will get you closer.
Ratio should be numeric to be graphed
Ratio is continuous, how should it be used to group?
For the colour on the data attribute map, the length of the colours is not long enough and risk should be numeric
I don't know exactly how to specify the ranges you'd like for the colours you'd like but this gets you closer using the automatic legend.
One way to get at this is to add the variable to the data set for each group and then you can control the colour of each group with the data attribute map. This would mean adding a column in the 'data' data set called ratio_group whcih maps to the values in the data attribute map table. Use that variable the group.

input area $ id $ var $ time $ exit $ ratio ;

For marker size look at the SIZE option under the MARKERATTRS option.
For grids, look at the GRID/MINORGRID options under the COLAXIS and ROWAXIS statements.
