That is a little hard to get to work. Had problems to complile V8 support myself last year.<br>I have seen nice examples in the past and this is on my personal TO DO list to try out, when I get some spare time.<br><br>3) Construct graphics with SQL. This is the way I have solved things myself. What I have done, is to construct circle sectors for instance with spatial sql expressions. I wrap GDAL sql expression with spatialite syntax in VRT files. These can then be used "on the fly" within mapserver or for preprossing of the data.<br>I could show some examples if any one is interested.<br><br>Actually I heard that someone was doing dynamic SVGs but I don't now the procedure for that.<br><br>/Lars Schylberg<br><br><br>December 9, 2017 12:56 PM, "Björn Danielsson" <<a target="_blank" tabindex="-1" href="mailto:%22Bj%C3%B6rn%20Danielsson%22%20<bjorn.danielsson@falubo.se>">bjorn.danielsson@falubo.se</a>> wrote:<br> <blockquote><div><div> <div style="font-family: tahoma;color: rgb(0, 0, 0);font-size: 13.3333px;font-weight: 400;font-style: normal">Hi,</div> <div style="font-family: tahoma;color: rgb(0, 0, 0);font-size: 13.3333px;font-weight: 400;font-style: normal">Is it possible to create dynamic symbols on the fly with regard to some data in a polygon, and place them on the map?</div> <div style="font-family: tahoma;color: rgb(0, 0, 0);font-size: 13.3333px;font-weight: 400;font-style: normal">Piecharts etc.</div> <div style="font-family: tahoma;color: rgb(0, 0, 0);font-size: 13.3333px;font-weight: 400;font-style: normal">SVG?</div> <div style="font-family: tahoma;color: rgb(0, 0, 0);font-size: 13.3333px;font-weight: 400;font-style: normal"></div> <div style="font-family: tahoma;color: rgb(0, 0, 0);font-size: 13.3333px;font-weight: 400;font-style: normal">Björn Danielsson</div> <div style="font-size: 13.3333px;font-family: tahoma;color: rgb(0, 0, 0);font-weight: 400;font-style: normal"></div> <div style="font-family: tahoma;color: rgb(0, 0, 0);font-size: 13.3333px;font-weight: 400;font-style: normal"></div> </div></div></blockquote> <br><br><signature></signature> </div></body></html>
