What is a correlation heatmap?

A correlation heatmap uses colored cells, typically in a monochromatic scale, to show a 2D correlation matrix (table) between two discrete dimensions or event types. … Correlation heatmaps are ideal for comparing the measurement for each pair of dimension values.

How do I make my Matplotlib plot bigger?

We may want to set the size of a figure to a certain size. You may want to make the figure wider in size, taller in height, etc. We can do this with matplotlib using the figsize attribute. The figsize attribute allows us to specify the width and height of a figure in unit inches.

imagesc( C ) displays the data in array C as an image that uses the full range of colors in the colormap. Each element of C specifies the color for one pixel of the image. … imagesc(‘CData’, C ) adds the image to the current axes without replacing existing plots. This syntax is the low-level version of imagesc(C) .
