Plot a bar chart comparing observed (measured) and modelled concentrations

plot_comparison_bars.Rd

This function produces a plot comparing modelled and measured concentrations. For long-term data, the provided annual averaged measured data is visualised alongside the performance acceptability range of the observations. For short-term data, the RMSE and RMSU*0 are visualised.

Usage

plot_comparison_bars(
  stats,
  stats2 = NULL,
  color_obs = "grey85",
  color_mod = "black",
  color_outline = "black",
  interactive = FALSE,
  show_annotations = FALSE,
  gp = grid::gpar(fontsize = 10)
)

Arguments

stats, stats2

The output of summarise_mqo_stats(). All relevant information (e.g., term, params_fixed, etc.) will be passed to this function from the statistics object. stats is compulsory and stats2 optional. If both are provided, stats and stats2 should be different terms (one short and one long). In that case, short-term stats are plotted preferentially but the long-term stats will be annotated if show_annotations = TRUE.

color_obs, color_mod, color_outline

The colours to use to fill the 'observation' bars, 'modelled' bars, and for the outlines/error bars. Can be expressed as hex codes, or any colours listed in colors().

interactive

If FALSE, the default, a static ggplot2 graphic will be returned which can be saved as a PNG, SVG, or other similar format. If TRUE, a dynamic HTML widget will be returned created by plotly.

show_annotations

Should the figure be annotated with input parameters and complementary performance indicators? These are useful extra detail, but can overcrowd the plotting area.

gp

A grid::gpar() object passed to grid::textGrob(), used to control the appearance of the parameter & indicator annotations when show_annotations = TRUE and interactive = FALSE. fontsize is likely the most useful argument, but many options are available through grid::gpar().

Examples

plot_comparison_bars(
  summarise_mqo_stats(demo_longterm, pollutant = "PM10")
)
#> ! term assumed to be 'long'.
#> ℹ If this is incorrect, please specify the data's term using the term argument.


plot_comparison_bars(
  summarise_mqo_stats(demo_shortterm, pollutant = "PM10")
)
#> ! term assumed to be 'short'.
#> ℹ If this is incorrect, please specify the data's term using the term argument.
