Tomas: I use OWTChart in cases like this (http://www.maptools.org/owtchart/index.phtml). You just feed it the data out of a MapServer query template and it sends you a gif. Embed that call into an image tag and there you have it- a dynamic graph sitting right along side your table. Here's an example page using this technique: http://www.dnr.state.mn.us/hunting/deer/mapit2004.html?imgxy=174.5+174.5&root=%5Broot%5D&map=%2Fusr%2Flocal%2Fwww%2Fdocs_maps%2Fwildlife%2Fwhitetail%2Fmain2004.map&imgext=74105.727952+4774937.053875+798393.592828+5499224.918751&layer=total&zoom=1&mode=query&img.x=213&img.y=108 The bar graphs data are nothing more than attributes in the shapefile. There are other options as well, but this should get you started. Steve >>> Tomas Zajc <[email protected]> 02/01/06 1:46 PM >>> I'm using mapserver to display some atmospherichal data. I got a shapefile with lat lon and 39 attributes. Each attribute is a concentration of gas in the atmosphere for 39 altitudes. The map displays the measurement points (lat long) and when you query that point you get an html with a two column table (high - concentration). Besides the table it would be nice to have a graph high-concentration. I know some php programs that can plot data from a data files like csv o txt (http://ftp.gnus.org/circus/chart/chart-manual.php). The problem is that i don't know how to generate a data file from mapserver. Any sugestion? I am generating the shapefiles so i may generate other "auxiliary" files...
