Implementation of line graph using SVG
Hello everyone
I have the measurement table in which datetime and value and other info is stored and i want to display line charts according to the table data..
I already implement to draw a line graph in asp.net and vb.net but it slow down the speed of site..
So i want to draw the line graph using SVG..
So anyone who has implemented this SVG concept please give me some code and explaination regarding it...

I have tried to give you an example (in very simple terms). This would take place of your standard record results printout:
response.write "<line x1='"& x1var &"' y1='"& y1var &"' x2='"& x2var &"' y2='"& y2var &"' style=""stroke:rgb(99,99,9
Suppose you are creating a bar graph to list people's grades.. basically what you would do (in ASP):
dim i
i = 0 'record counter
Connect to DB
Run your Query (Select statement)
If NOT EOF Then
response.write "<g>" 'start group label - you'll need to specify more stuff in here
While NOT.Eof
response.write "<line x1='"& i &"' y1='0' x2='"& i & "' y2='"& rs("grade") &"' style=""stroke:blue; stroke-width:'2' ""/>"
i = i + 1 'increment counter to move to next bar slot
rs.movenext
Loop
response.write "</g>" 'end group label
End If
So basically while you're going thru each record: plot it and then move x over one and do the same thing again.
I only have experience in VML so syntax is not absolutely correct, but hopefully you get the idea.
