I still think the data in table form does make some trends very visible. Like the near-constancy of brown malt. The rise of black malt and its replacement by chocolate malt. Flirts with sugar in the late 19th century before its definitive adoption in 1902.
No adjuncts. Apart from maybe tiny quantities of oats, which may have been in flaked form. Though they could also have been malted. The records don't specify the form. Their presence is purely on account of Porter being parti-gyled with Stout. Some of which was sold as Oatmeal Stout. The tiny amount of oats was simply there for legal reasons.
The ups and downs of brown malt are also very evident. From a peak of 35% to a low of, well, nothing. Or 3%, if you look at it another way.
Mild malt takes a bow towards the end of Porter's life, making up part of the base malt. I assume for financial reasons.

Hi Ron - another good chart type for this type of info is the Area chart - you can use it to show the proportion of each ingredient, scaled up to 100% like in this table, and its a little easier on the eye than the stacked bar for a lot of data like this. If you have additional volume data - say, total amount of porter produced in barrels per year, for instance, you can also show that data together with the variation in ingredients over time - so both variation in volume and composition - with, say, time on the x axis and volume/ percentage on the y axis. Excel makes it dead easy - just select the data and hit the relevant chart type. If you google Area charts, you'll see examples (harder to explain in text!).
