The above heatmap shows the wins at Away for all EPL teams from 1995 to 2018. The colour code is given on the right hand side with darker colors for more wins and lighter for less. The number of wins are normalised to fall within the range of 0-1 which is easier to represent. We can see that the Big Six teams are a bit stronger away than the weaker ones. This graph is produced using plotly and is also interactive.
