rAmCharts - amCandlestick

Parameters

  • data: a dataframe with at least 5 columns: category, open (numeric), close (numeric), low (numeric), high (numeric).
  • dataDateFormat: a character, default ‘NULL’. Even if your chart parses dates, you can pass them as strings in your data - all you need to do is to set data date format and the chart will parse dates to date objects. Please note that two-digit years (YY) as well as literal month names (MMM) are NOT supported in this setting.
  • minPeriod: a character. minPeriod Specifies the shortest period of your data. This should be set only if dataDateFormat is not ‘NULL’. Possible period values: fff - milliseconds, ss - seconds, mm - minutes, hh - hours, DD - days, MM - months, YYYY - years. It’s also possible to supply a number for increments, i.e. ‘15mm’ which will instruct the chart that your data is supplied in 15 minutes increments.
  • positiveColor: a character, color for positive values. Must be in hexadecimal if you plan to export the chart.
  • negativeColor: a character, color for negative values. Must be in hexadecimal if you plan to export the chart.
  • names: a character, names for the tooltips.
  • xlab: a character, label for x-axis.
  • ylab: a character, label for y-axis.
  • horiz: a boolean, TRUE for an horizontal chart, FALSE for a vertical one.
  • …: other parameters called in amOptions.
