That chart shows the overall tonal balance, but it can't show the sharp dips we would expect to see from a crossover null.
If the polarity is right, you'll see nulls at approximately +-20 degrees above and below the speaker. If it's wrong, you'll see a null on-axis.
Watch this video to understand what I'm expecting to see:
Vertical Nulls
