Differences between pseudocolor plot and heatmap?

I found some materials using the word `pseudocolor plot' and I think that it's just a heatmap. Is there any difference between them?

A heatmap is effectively a pseudocolor plot with labelled rows and columns. So, basically heatmap is a pseudocolor plot based on a pandas DataFrame rather than a matrix. Basic difference is in the plotting methods available but you can convert the matrix to dataframe and vice-versa.
