Hi Burni

You can access the plot function of the plugin.

http://rsb.info.nih.gov/ij/developer/source/ij/plugin/frame/Fitter.java.html

You need to pass the plot function the CurveFitter instance.  This line
should do it -

ij.plugin.frame.Fitter.plot(fitter);

//////////////////////////////////////////////////////////////////////////

double[] x = new double [] {0, 1, 2, 3, 4, 5};
double[] y = new double [] {0, 0.9, 4.5, 8, 18, 24};

CurveFitter fitter=new CurveFitter(x, y);

fitter.doFit(1);

double[] results=fitter.getParams();

for (double d:results)
{
    print(d);
}

ij.plugin.frame.Fitter.plot(fitter);
