Graph

The result of each candidate's opinion poll result is denoted by a plot point, or a "period". The lines denote moving averages of the last three polls for each candidate; as pollsters may use different methodologies, it is invalid to plot each period from all pollsters as if it is a single series. Hence, a moving average is used to link all polls from all pollsters into one series. Some candidates may not appear on some polls, and these do not include candidates who are not on the final list but were included in other polls. The twelfth ranking candidate in each poll is denoted by a line, for easy reference.

Seats won

The first figure denotes the number of candidates from the party or coalition that made it to the top 12 in each survey; the figures inside the parenthesis are other candidates that made it within the margin of error. The figure of the party or coalition the most seats is highlighted; those that outright win a majority of seats contested is italicized, while the party or coalition that outright wins a majority of seats in the Senate is boldfaced.
Some of the totals might not add up as most slates have shared candidates.
