Daten aufbereiten

daten <- penguins %>% 
  group_by(species) %>% 
  summarise(m_schnabellaenge = mean(bill_length_mm, na.rm = TRUE))

Diagramm mit ggplot2

daten %>% 
  ggplot(mapping = aes(x = reorder(species, m_schnabellaenge), y = m_schnabellaenge)) +
  geom_col(fill = "#9FC131") +
  labs(title = "Schnabellänge von drei Pinguinarten", 
       x = "Pinguinarten", 
       y = "Mittlere Schnabellänge") +
  theme_dv()

Diagramm mit plotly

Alternativ ermöglicht die Funktion ggplotly() das Erstellen eines plotly-Objektes aus einem ggplot2-Plot.

plot_ly(data = daten, 
        x = reorder(daten$species, daten$m_schnabellaenge), 
        y = daten$m_schnabellaenge, 
        type = "bar", 
        color = I("#9FC131")) %>% 
  layout(title = 
           list(
             x = 0.055,
             y = 0.99, 
             font = list(size = 22), 
             text = "Schnabellänge von drei Pinguinarten"
           ), 
    xaxis = list(title = "Pinguinarten"), 
    yaxis = list(title = "Mittlere Schnabellänge"), 
    font = 
      list(
        family = "Manrope", 
        size = "14pt", 
        color = "#2d2926"
      ), 
    paper_bgcolor = "#f5f5f2", 
    plot_bgcolor = "#f5f5f2")

Diagramm mit echarts4r

daten %>% 
  arrange(m_schnabellaenge) %>% 
  e_charts(x = species) %>% 
  e_bar(serie = m_schnabellaenge) %>% 
  e_axis_labels(x = "Pinguinarten", 
                y = "Mittlere Schnabellänge") %>% 
  e_theme_custom(theme = "theme/datenpfad.json") %>% # Optional Theme importieren
  e_title(text = "Schnabellänge von drei Pinguinarten", 
          textStyle = list(fontWeight = 700, 
                           fontSize = 22)) %>% 
  e_legend(left = "10%", 
           bottom = "0%", 
           orient = "horizontal") %>% 
  e_grid(top = "15%") %>% 
  e_x_axis(nameTextStyle = list(
    color = "#2d2926", 
    fontSize = 14
  )) %>% 
  e_y_axis(nameTextStyle = list(
    color = "#2d2926", 
    fontSize = 14
  )) %>% 
  e_tooltip(trigger = "axis", 
            axisPointer = list(type = "line")) %>% 
  e_toolbox_feature(feature = "saveAsImage", 
                    backgroundColor = "#ffffff") %>% 
  e_toolbox_feature(feature = "restore") %>% 
  e_toolbox_feature(feature = "dataZoom")

Diagramm mit gganimate

ggplot2_plot <- 
  daten %>% 
  ggplot(mapping = aes(x = reorder(species, m_schnabellaenge), y = m_schnabellaenge)) +
  geom_col(fill = "#9FC131") +
  labs(title = "Schnabellänge von drei Pinguinarten", 
       x = "Pinguinarten", 
       y = "Mittlere Schnabellänge") +
  theme_dv_gganimate()

## Animation hinzufügen
ggplot2_plot + 
  transition_states(states = gruppe, 
                    transition_length = 2, 
                    state_length = 1) +
  ease_aes("sine-in-out")
