rAmCharts - amFunnel

Parameters

  • data: a dataframe with at least 2 columns: value (numeric, positive), and description (character). See data_funnel for example. You can add a third column “color” (character, colors in hexadecimal) to specify the colors.
  • neck_height: a numeric, value between 0 and 100 : if a bottleneck is desired, this value determines its heigh. Default to NULL.
  • neck_width: a numeric, value between 0 and 100 : if a bottleneck is desired, this value determines its width. Default to NULL.
  • depth: a numeric, between 0 and 100. If superior to 0, chart is displayed in 3D. Only for pyramid chart (without a bottleneck).
  • inverse: a boolean, if TRUE, the funnel chart will be inversed.
  • label_side: a character, defines the label position : “right” or “left”.
  • margin_right: a numeric, margin at the right side.
  • margin_left: a numeric, margin at the left side.
  • …: other parameters called in amOptions.
