- __init__(data, show_legend=True, flip=True, threshold=None)¶
- Parameters
- datadict or DataFrame
Correlation matrix or data (correlation will be calculated for each variable pair). Data will be recognized as correlation matrix if it has a square shape and all values are in range -1.0..+1.0 or NaN.
- show_legendbool, default=True
If True legend is shown.
- flipbool, default=True
If True the y axis is flipped.
- thresholdfloat, default=0.0
Minimal correlation abs value to be included in result. Accept values between 0 and 1.
- points(type=None, diag=None)¶
Method defines correlation matrix layer drawn by points to the plot.
- Parameters
- type{‘upper’, ‘lower’, ‘full’}
Type of matrix. Default - contextual.
- diagbool
Determines whether to fill the main diagonal with values or not. Default - contextual.
- Returns
- corr_plot
Correlation plot specification.
- labels(type=None, diag=None, map_size=None, color=None)¶
Method defines correlation matrix layer drawn with geom_text to the plot.
- Parameters
- type{‘upper’, ‘lower’, ‘full’}
Type of matrix. Default - contextual.
- diagbool
Determines whether to fill the main diagonal with values or not. Default - contextual.
- map_sizebool
If True, then absolute value of correlation is mapped to text size. If False - the text size is constant. Default - contextual.
- colorstr
Set text color. Default - contextual.
- Returns
- corr_plot
Correlation plot specification.
- tiles(type=None, diag=None)¶
Method defines correlation matrix layer drawn as square tiles to the plot.
- Parameters
- type{‘upper’, ‘lower’, ‘full’}
Type of matrix. Default - contextual.
- diagbool
Determines whether to fill the main diagonal with values or not. Default - contextual.
- Returns
- corr_plot
Correlation plot specification.
- palette_gradient(low, mid, high)¶
Set scale_color_gradient2() and scale_fill_gradient() for corr plot.
- Parameters
- lowstr
Color for low end of gradient (correlation -1).
- midstr
Color for mid point (correlation 0).
- highstr
Color for high end of gradient (correlation 1).
- Returns
- corr_plot
Correlation plot specification.
- palette_BrBG()¶
Set scale_color_brewer() with BrBG palette for corr plot.
- Returns
- corr_plot
Correlation plot specification.
- palette_PiYG()¶
Set scale_color_brewer() with PiYG palette for corr plot.
