説明

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: bildschirmfoto 2015-02-15 um 22 36 54

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

Many thanks in advance!

調査方針: The issue asks for contour plot functionality in Breeze, a Scala numerical library. The first step is to explore the current plotting API, which is likely in the 'plot' package (e.g., breeze.plot.*). Check if there are any previous discussions or branches that attempted this. Since the library has not added this feature in many years, it may require significant new code or integration with an external library like JFreeChart or Plotly. Look at how scatter plots and line plots are implemented for guidance.
