Incorrect plot

[mikesolem]

First off, thanks for creating this. It is very useful!

This data results in a graph with a flat line with all values at 0.00.

func main() {
data := []float64{.2, .3, .2}
graph := asciigraph.Plot(data)
fmt.Println(graph)
}

i can confirm this, this happens because config.Height is an int, when you use a series with values less than 1 the calculated height will be 0.x something but when it gets set to an int it gets rounded off to 0, that 0 is then used for ratio calculation which in turn becomes zero and then zeroes everything out

@guptarohit if in case of a 0 height you override it with 1 this graph would plot correctly
