Plot voter shares observed in one survey — gg

Bar chart of the raw voter shares observed in one survey. Additionally to plotting positive voter shares, the function can be used to plot party-specific differences (e.g. between a survey and the election result), including negative numbers.

gg_survey(data, colors = NULL, labels = NULL, annotate_bars = TRUE, hurdle = 5)

Arguments

data: Scraped dataset containing one row per party in the column party and the observed voter share in the column percent
colors: Named vector containing party colors. If NULL (default) tries to guess color based on party names, gray otherwise.
labels: Named vector containing party labels. If NULL (default) tries to guess party names from data.
annotate_bars: If TRUE (default) bars are annotated by the respective vote share (percentage).
hurdle: Hurdle for single parties to get into the parliament, e.g. '5' for '5%'. If set to NULL no horizontal line is plotted. The horizontal line can be suppressed using NULL.

Value

A ggplot object displaying voter shares as a bar chart.
