Contour plots

[ZeroHypotheses]

Hi @dlwh,

is it possible to draw contour plots like in octave, e.g. contour(u, v, z, [0, 0], 'LineWidth', 2)? I wanted to draw a polynomial decision boundary for logistic regression with scala/breeze like this:

The scatter plot for the data works fine, but I cant find a way to plot such a decision boundary.

Many thanks in advance!

i don't think so, no. :(

I wonder if I could draw this with the underlying JFreeChart library "natively" and do a figure.subplot(0) += jFreeChartContourPlot afterwards to get it back to Scala/Breeze. Since this is quite new to me any suggestions or help is appreciated.

that's a good idea for an API addition.

Take a look at SmilePlot, the visualization library of the Statistical Machine Intelligence & Learning Engine, written in Java.
