Also, I made some more researches today... I think a way to obtain what I need is to have a table on the db that contains something like this: geomId Geom Year Val1 Val2 Val3... ValN 1 .... 2008 3 3 4 7 1 .... 2009 3 5 4 150 1 .... 2010 3 5 4 15 1 .... 2011 6 50 14 75 2 .... 2008 6 50 14 7 .... and so on. But in this way I suppose the server would redraw the same geometry different times (but maybe not, if the geometries are id-based). An alternative could be to have a table with data (gid, year, vals...) and one with geometries, and then use a geoserver sql view with parameters in order to select only geometries for a given year (in a choropleth map i can just show one val and one year at a time...).
But at this point, another problem comes out. If I click on the map I would like to show out a graph of the selected values for each year. I can use the getFeature or getfeatureinfo for this, but...can i pass to the server different parameters in order to obtain all the values needed for a single geometry?... Sorry for all these questions :) -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Best-way-to-have-different-information-shown-on-the-same-geometries-tp5042581p5044578.html Sent from the OpenLayers Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list us...@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/openlayers-users
