          array
              Sets the data corresponding the length of each error
              bar. Values are plotted relative to the underlying
              data.
          arrayminus
              Sets the data corresponding the length of each error
              bar in the bottom (left) direction for vertical
              (horizontal) bars Values are plotted relative to the
              underlying data.
          arrayminussrc
              Sets the source reference on Chart Studio Cloud for
              arrayminus .
          arraysrc
              Sets the source reference on Chart Studio Cloud for
              array .
          color
              Sets the stoke color of the error bars.
          symmetric
              Determines whether or not the error bars have the same
              length in both direction (top/bottom for vertical bars,
              left/right for horizontal bars.
          thickness
              Sets the thickness (in px) of the error bars.
          traceref
  
          tracerefminus
  
          type
              Determines the rule used to generate the error bars. If
              *constant`, the bar lengths are of a constant value.
              Set this constant in `value`. If "percent", the bar
              lengths correspond to a percentage of underlying data.
              Set this percentage in `value`. If "sqrt", the bar
              lengths correspond to the square of the underlying
              data. If "data", the bar lengths are set with data set
              `array`.
          value
              Sets the value of either the percentage (if `type` is
              set to "percent") or the constant (if `type` is set to
              "constant") corresponding to the lengths of the error
              bars.
          valueminus
              Sets the value of either the percentage (if `type` is
              set to "percent") or the constant (if `type` is set to
              "constant") corresponding to the lengths of the error
              bars in the bottom (left) direction for vertical
              (horizontal) bars
          visible
              Determines whether or not this set of error bars is
              visible.
          width
              Sets the width (in px) of the cross-bar at both ends of
              the error bars.
