Hello all .

I’m still kind of new to Ruby and trying to graph data in real-time but

I

can’t seem to find a suitable graphing engine. I’ve sniffed around

using my

friend Google, but I didn’t find anything concrete. Has anyone out

there

done a GUI graph that updates in real-time (something simple like a line

chart)? Here’s some pseudocode to help get my point across:

graph = SomeGraphEngine.new

graph.type = “line”

xvalues = Array.new

yvalyes = Array.new

for num in ( 0 … 36 )

```
xvalues << Float( num * 10.0 + 50 )
yvalues << Float( Math.sin( num * Math.pi / 15.0 ) * 16.0 )
```

graph.coords( xvalues, yvalues )

graph.draw

end
