Imshow nan values
WitrynaIt is often desirable to show data which depends on two independent variables as a color coded image plot. This is often referred to as a heatmap. If the data is categorical, this would be called a categorical heatmap. Matplotlib's imshow function makes production of such plots particularly easy. WitrynaChanged imshow to skip waiting for user input if wait_ms=0. Added (RGB) colormap handles for convenience. Drop support for deprecated Python version 3.5. ... Prevent nan values caused by floating point precision issues in the cam_projections submodule. Remove the (empty) tracking submodule ...

WitrynaNotes. When density is True, then the returned histogram is the sample density, defined such that the sum over bins of the product bin_value * bin_area is 1.. Please note that the histogram does not follow the Cartesian convention where x values are on the abscissa and y values on the ordinate axis. Rather, x is histogrammed along the first …
