Hopefully, there's an eaier answer for you than what we found. But just in case...
Our little company wanted to display reference maps related to a user's queries. Unfortunately, the map images couldn't be static (i.e. an unchanging graphic image of a map) to represent the data being asked for. So rather than pay fees to MapQuest and the like, we looked into making our own. What we ended up doing was creating a java class library that would use Sun's Advanced Graphics Library along with our own data files to create graphics on the fly.
Now, how did we interface that with FoxWeb/FoxPro? Our FoxWeb script would create a java server page file (filename.jsp) with HTML and a JSP function invocation:
<html>
<head>
.
</head>
<body>
<H1>Show Graphic!</h1>
.
.
<jsp:include page="/servlet/MultiPlot">
<jsp:param name="var1" value="12345" />
<jsp:param name="var2" value="A"
</jsp:include>
.
</body>
</html> |
we would then redirect the foxweb script to the newly created .jsp file:
sn="filename.jsp" &&-- this file was created just before this point! link=" http://localhost/"+snresponse.redirect(link) |
This would force the server to process the JSP file and execute the JSP code in it. In our case, the JSP function created a graphic file (you can choose any kind, but I personally recommend a PNG file) on the server and returned an HTML image-link to that file.
Like I said, I hope there's an easier way for you. The Sun graphics library is not very well documented - a real pity given how profoundly useful it could be for situations like this.

I am making a programm, using Foxpro and Foxweb.
But some of the data (temperatures and the use of energy) I want to show in a graph.
Is this possible? What kind of program do I need to use for that?
it must be quick and the graphs must be "nice"
Thanks.
