Useful introductory expressions:

As is shown / illustrated by the graph,
Example: The graph shows the percentage of children using supplements in a place over a year.

Useful time expressions:

from ... to / between ... and (from June to August... between June and August...)
during (during the first three months...)

Warning!
Per cent is the word form of the symbol %. We can write 10% or 10 per cent. Percentage is the noun form: The percentage of children using supplements. NOT The percent of children...

Note!You can use a combination of adjective + noun, or verb + adverb, to avoid repeating the same phrase.
Example: There was a sharp decrease in the numbers. The numbers decreased sharply.
