my dissertation is (companies analysis and valuation in chemical manufacturing industry) and this is the industry chapter.

I have done it but it needs some improvement in the:

1language: the way that the information presented and how to explain graphs and tables.
2graphs: they need to be improved by showing all elements (what I have done is basic graphs).
3please write a summery of this chapter of 200 words in the end.
