## checkerboard_plot *checkerboard_plot(ary, cell_colors=('white', 'black'), font_colors=('black', 'white'), fmt='%.1f', figsize=None, row_labels=None, col_labels=None, fontsize=None)* Plot a checkerboard table / heatmap via matplotlib. **Parameters** - `ary` : array-like, shape = [n, m] A 2D Nnumpy array. - `cell_colors` : tuple or list (default: ('white', 'black')) Tuple or list containing the two colors of the checkerboard pattern. - `font_colors` : tuple or list (default: ('black', 'white')) Font colors corresponding to the cell colors. - `figsize` : tuple (default: (2.5, 2.5)) Height and width of the figure - `fmt` : str (default: '%.1f') Python string formatter for cell values. The default '%.1f' results in floats with 1 digit after the decimal point. Use '%d' to show numbers as integers. - `row_labels` : list (default: None) List of the row labels. Uses the array row indices 0 to n by default. - `col_labels` : list (default: None) List of the column labels. Uses the array column indices 0 to m by default. - `fontsize` : int (default: None) Specifies the font size of the checkerboard table. Uses matplotlib's default if None. **Returns** - `fig` : matplotlib Figure object. **Examples** For usage examples, please see [https://rasbt.github.io/mlxtend/user_guide/plotting/checkerboard_plot/](https://rasbt.github.io/mlxtend/user_guide/plotting/checkerboard_plot/)
