values_legend {rKolada}

Create KPI long-form descriptions to add to a plot

Description

In a Kolada values table, only KPI ID names are preserved. But in plots you often want to add a legend to explain what each KPI ID represents. But since KPI explanations are mostly relatively wordy, ggplot2 legends are under-dimensioned for this task. values_legend returns a string which can conveniently be used as caption to a plot instead.

Usage

values_legend(values_df, kpi_df)

Arguments

values_df

A Kolada value table, as created by get_values.

kpi_df

A KPI table, e.g. as created by get_kpi.

Value

A string which should be used as caption in a plot.
