Running your notebook (with Python 3) and hovering some points in the heatmap led to right displayed values as you can see in these images. From the output, we can see that instead of a color scale that shows up the value range, discrete color representation is showing results with exact values. Sequential color scales are appropriate for most continuous data, but in some cases it can be helpful to use a diverging or cyclical color scale (see below). px.bar(), discrete (also known as categorical or qualitative).
