Hello,
I'm looking for plotting a graph on my html pages. My final goal is to interface a little car with a web page. I'm a beginner on html& css. I know C and java. Could you advice me? I'm trying to find examples or tutorials about it.
One way of doing it is described here: HowTo: Using RRD - Round Robin Database - Arduino Yún - Arduino Forum
If that's something like you would want to do, I'm happy to answer questions. If they are directly related to that topic, it might be best to ask the questions in that topic, so that all of the information stays together.
Ok I begin by reading the entire topic and I keep you informed. Thanks.
Cool! I tried the example in this link HTML5 bidirection websocket (node ws) sketch to try. - Arduino Yún - Arduino Forum made by Roffee but i can't read my analogic input. The graph displays zero.
If you are using a modern HTML5 based browser, then SVG might be an easy way to do it.
Using the line and lineto commands.
I have this:

But my line 2 doesn't display!! maybe my code isn't right!!
This examle is from the TemperatureWebPanel example. Finally the right arduino code for having a good behavior is the same as temperaturewebpanel example but we have to remove every line which call client.println except the one which print the value you want to graph.
