Floats as coordinate values

Hi,

I need to draw on a window using single- or double-floats as coordinate val=
ues (I am plotting spectral analysis data, though not with the chart-widget=
). Is there an easy way to do this? Currently I am having to round my value=
s in order to see anything, which is OK, but inconvenient if I want to do f=
ine editing of data using the mouse. Might mixing in a scaling-stream work?

Many thanks,
