Obsolete. Use the alpha channel in error bar `color` to set the opacity.

Sets the source reference on plot.ly for  array .

Sets the source reference on plot.ly for  arrayminus .

Sets the calendar system to use with `x` date data.

Sets the calendar system to use with `y` date data.

Sets a reference between this trace's x coordinates and a 2D cartesian x axis. If *x* (the default value), the x coordinates refer to `layout.xaxis`. If *x2*, the x coordinates refer to `layout.xaxis2`, and so on.

Sets a reference between this trace's y coordinates and a 2D cartesian y axis. If *y* (the default value), the y coordinates refer to `layout.yaxis`. If *y2*, the y coordinates refer to `layout.yaxis2`, and so on.

Sets the source reference on plot.ly for  ids .

Sets the source reference on plot.ly for  customdata .

Sets the source reference on plot.ly for  hoverinfo .

Sets the source reference on plot.ly for  x .

Sets the source reference on plot.ly for  y .

Sets the source reference on plot.ly for  text .

Sets the source reference on plot.ly for  hovertext .

Sets the source reference on plot.ly for  textposition .

Sets the source reference on plot.ly for  r .

Sets the source reference on plot.ly for  t .

The data visualized by the span of the bars is set in `y` if `orientation` is set th *v* (the default) and the labels are set in `x`. By setting `orientation` to *h*, the roles are interchanged.

Specifies the location of the `text`. *inside* positions `text` inside, next to the bar end (rotated and scaled if needed). *outside* positions `text` outside, next to the bar end (scaled if needed). *auto* positions `text` inside or outside so that `text` size is maximized.

Sets the font used for `text` lying inside the bar.

Sets the font used for `text` lying outside the bar.

Constrain the size of text inside or outside a bar to be no larger than the bar itself.

Determines whether the text nodes are clipped about the subplot axes. To show the text nodes above axis lines and tick labels, make sure to set `xaxis.layer` and `yaxis.layer` to *below traces*.
