Generates line plot with markers on every value with index on a given value.

line_chart_markers_reference(
  data,
  x,
  series,
  series_labels,
  ref_val,
  ref_label = ref_val,
  interval = "months",
  styles = NULL
)

Arguments

data	data frame containing data to be plotted
x	vector containing time intervals of the values
series	vector containing names of columns in data with values to plot
series_labels	vector containing names of series to be shown on the plot
ref_val	numeric value of the index
ref_label	string defining a text that should be displayed in the referencing line. Set by default to index_val.
interval	intervals on x axis. The width of the bars depends on this parameter
styles	optional data frame with style names. Styles of the markers will be plotted accordingly.
