Im1 = grid.imshow(data, cmap='jet', interpolation='nearest') Im0 = grid.imshow(data, cmap='gray', interpolation='nearest') However, if img were an array of shape (M,N), then the cmap controls the colormap used to display the values. Per the help(plt.imshow) docstring:Ĭmap : ~, optional, default: None When img1 has shape (M,N,3) or (M,N,4), the values in img1 are interpreted as RGB or RGBA values. Then what does the second argument 'gray' do? Can someone explain all this to me? Any help appreciated. What does plt.imshow(img1, 'gray') do? I tried searching Google and all I could understand was that the 'gray' argument was a Color map. Plt.subplot(236),plt.imshow(constant,'gray'),plt.title('CONSTANT') Plt.subplot(233),plt.imshow(reflect,'gray'),plt.title('REFLECT') Plt.subplot(232),plt.imshow(replicate,'gray'),plt.title('REPLICATE')

Colormaps are often split into several categories based on their function (see, e.g., ): Sequential: change in lightness and often saturation of color incrementally, often using a single hue should be used for representing information that has ordering. The raw scores are then scaled (normalized) by the signed-means to allow forįinally the statistical significance of the connections adjusted for multiple While query methodology isĪgnostic to the specific similarity metric, the default choice is a non-parametric, two-tailed weighted gene-set enrichment score (Subramanian, A.
