With this, I would be tempted to split this into three point shapefiles and try
rendering them on top of each other in different orders applying different
styles to see how the picture/map looked. I think I tried, but did not find a
way to do it all in one go keeping all the data in the same shapefile.
The points I add in the foreground of my map:
// Add foreground0
// ---------------
private static void addForeground0(
MapContent result,
AGDT_StyleParameters styleParameters,
ArrayList<AGDT_Shapefile> foregroundDW_Shapefile0) {
if (foregroundDW_Shapefile0 != null) {
Iterator<AGDT_Shapefile> ite;
ite = foregroundDW_Shapefile0.iterator();
int indexx = 0;
while (ite.hasNext()) {
AGDT_Shapefile sf = ite.next();
FeatureLayer foregroundFeatureLayer0;
foregroundFeatureLayer0 = sf.getFeatureLayer(
styleParameters.getForegroundStyle0().get(indexx));
result.addLayer(foregroundFeatureLayer0);
indexx++;
}
}
}
That code is from:
https://github.com/agdturner/digital-welfare/blob/master/src/main/java/uk/ac/leeds/ccg/andyt/projects/digitalwelfare/mapping/DW_Geotools.java
point
My DW_ project code depends on the following where I have tried to move all my
generic geotools type code too (as you may recall):
https://github.com/agdturner/agdt-geotools
Interested to learn if you figure out a way to do this keeping all the data in
a single shapefile. There may be a way to do this with classifiers which I use
to do graduated shading. But with this, you may be more restricted in the
colours and styles of your points.
Please let me know if this helps or if you want more details (though it might
take me a week or so to respond from now). Thanks also for your reply to my
earlier message. I will be taking a good look at your work and hopefully
referring to it in due course.
I will be getting back to coding in the next week or so having had a few week
doing other things.
Best wishes,
Andy

Subject: [Geotools-gt2-users] Help with styling
I have a point shape file with one attribute which can be one of -1,0,1.
I’d like to set up a style with three colors. Can someone point me in the
right direction?
Thanx
