        The 'colorbar' property is an instance of ColorBar
        that may be specified as:
          - An instance of :class:`plotly.graph_objs.histogram.marker.ColorBar`
          - A dict of string/value properties that will be passed
            to the ColorBar constructor

            Supported dict properties:

                bgcolor
                    Sets the color of padded area.
                bordercolor
                    Sets the axis line color.
                borderwidth
                    Sets the width (in px) or the border enclosing
                    this color bar.
                dtick
                    Sets the step in-between ticks on this axis.
                    Use with `tick0`. Must be a positive number, or
                    special strings available to "log" and "date"
                    axes. If the axis `type` is "log", then ticks
                    are set every 10^(n*dtick) where n is the tick
                    number. For example, to set a tick mark at 1,
                    10, 100, 1000, ... set dtick to 1. To set tick
                    marks at 1, 100, 10000, ... set dtick to 2. To
                    set tick marks at 1, 5, 25, 125, 625, 3125, ...
                    set dtick to log_10(5), or 0.69897000433. "log"
                    has several special values; "L<f>", where `f`
                    is a positive number, gives ticks linearly
                    spaced in value (but not position). For example
                    `tick0` = 0.1, `dtick` = "L0.5" will put ticks
                    at 0.1, 0.6, 1.1, 1.6 etc. To show powers of 10
                    plus small digits between, use "D1" (all
                    digits) or "D2" (only 2 and 5). `tick0` is
                    ignored for "D1" and "D2". If the axis `type`
                    is "date", then you must convert the time to
                    milliseconds. For example, to set the interval
                    between ticks to one day, set `dtick` to
                    86400000.0. "date" also has special values
                    "M<n>" gives ticks spaced by a number of
                    months. `n` must be a positive integer. To set
                    ticks on the 15th of every third month, set
                    `tick0` to "2000-01-15" and `dtick` to "M3". To
                    set ticks every 4 years, set `dtick` to "M48"
                exponentformat
                    Determines a formatting rule for the tick
                    exponents. For example, consider the number
                    1,000,000,000. If "none", it appears as
                    1,000,000,000. If "e", 1e+9. If "E", 1E+9. If
                    "power", 1x10^9 (with 9 in a super script). If
                    "SI", 1G. If "B", 1B.
                labelalias
                    Replacement text for specific tick or hover
                    labels. For example using {US: 'USA', CA:
                    'Canada'} changes US to USA and CA to Canada.
                    The labels we would have shown must match the
                    keys exactly, after adding any tickprefix or
                    ticksuffix. For negative numbers the minus sign
                    symbol used (U+2212) is wider than the regular
                    ascii dash. That means you need to use −1
                    instead of -1. labelalias can be used with any
                    axis type, and both keys (if needed) and values
                    (if desired) can include html-like tags or
                    MathJax.
                len
                    Sets the length of the color bar This measure
                    excludes the padding of both ends. That is, the
                    color bar length is this length minus the
                    padding on both ends.
                lenmode
                    Determines whether this color bar's length
                    (i.e. the measure in the color variation
                    direction) is set in units of plot "fraction"
                    or in *pixels. Use `len` to set the value.
                minexponent
                    Hide SI prefix for 10^n if |n| is below this
                    number. This only has an effect when
                    `tickformat` is "SI" or "B".
                nticks
                    Specifies the maximum number of ticks for the
                    particular axis. The actual number of ticks
                    will be chosen automatically to be less than or
                    equal to `nticks`. Has an effect only if
                    `tickmode` is set to "auto".
                orientation
                    Sets the orientation of the colorbar.
                outlinecolor
                    Sets the axis line color.
                outlinewidth
                    Sets the width (in px) of the axis line.
                separatethousands
                    If "true", even 4-digit integers are separated
                showexponent
                    If "all", all exponents are shown besides their
                    significands. If "first", only the exponent of
                    the first tick is shown. If "last", only the
                    exponent of the last tick is shown. If "none",
                    no exponents appear.
                showticklabels
                    Determines whether or not the tick labels are
                    drawn.
                showtickprefix
                    If "all", all tick labels are displayed with a
                    prefix. If "first", only the first tick is
                    displayed with a prefix. If "last", only the
                    last tick is displayed with a suffix. If
                    "none", tick prefixes are hidden.
                showticksuffix
                    Same as `showtickprefix` but for tick suffixes.
                thickness
                    Sets the thickness of the color bar This
                    measure excludes the size of the padding, ticks
                    and labels.
                thicknessmode
                    Determines whether this color bar's thickness
                    (i.e. the measure in the constant color
                    direction) is set in units of plot "fraction"
                    or in "pixels". Use `thickness` to set the
                    value.
                tick0
                    Sets the placement of the first tick on this
                    axis. Use with `dtick`. If the axis `type` is
                    "log", then you must take the log of your
                    starting tick (e.g. to set the starting tick to
                    100, set the `tick0` to 2) except when
                    `dtick`=*L<f>* (see `dtick` for more info). If
                    the axis `type` is "date", it should be a date
                    string, like date data. If the axis `type` is
                    "category", it should be a number, using the
                    scale where each category is assigned a serial
                    number from zero in the order it appears.
                tickangle
                    Sets the angle of the tick labels with respect
                    to the horizontal. For example, a `tickangle`
                    of -90 draws the tick labels vertically.
                tickcolor
                    Sets the tick color.
                tickfont
                    Sets the color bar's tick label font
                tickformat
                    Sets the tick label formatting rule using d3
                    formatting mini-languages which are very
                    similar to those in Python. For numbers, see: h

                tickformatstopdefaults
                    When used in a template (as layout.template.dat
                    a.histogram.marker.colorbar.tickformatstopdefau
                    lts), sets the default property values to use
                    for elements of
                    histogram.marker.colorbar.tickformatstops
                ticklabeloverflow
                    Determines how we handle tick labels that would
                    overflow either the graph div or the domain of
                    the axis. The default value for inside tick
                    labels is *hide past domain*. In other cases
                    the default is *hide past div*.
                ticklabelposition
                    Determines where tick labels are drawn relative
                    to the ticks. Left and right options are used
                    when `orientation` is "h", top and bottom when
                    `orientation` is "v".
                ticklabelstep
                    Sets the spacing between tick labels as
                    compared to the spacing between ticks. A value
                    of 1 (default) means each tick gets a label. A
                    value of 2 means shows every 2nd label. A
                    larger value n means only every nth tick is
                    labeled. `tick0` determines which labels are
                    shown. Not implemented for axes with `type`
                    "log" or "multicategory", or when `tickmode` is
                    "array".
                ticklen
                    Sets the tick length (in px).
                tickmode
                    Sets the tick mode for this axis. If "auto",
                    the number of ticks is set via `nticks`. If
                    "linear", the placement of the ticks is
                    determined by a starting position `tick0` and a
                    tick step `dtick` ("linear" is the default
                    value if `tick0` and `dtick` are provided). If
                    "array", the placement of the ticks is set via
                    `tickvals` and the tick text is `ticktext`.
                    ("array" is the default value if `tickvals` is
                    provided).
                tickprefix
                    Sets a tick label prefix.
                ticks
                    Determines whether ticks are drawn or not. If
                    "", this axis' ticks are not drawn. If
                    "outside" ("inside"), this axis' are drawn
                    outside (inside) the axis lines.
                ticksuffix
                    Sets a tick label suffix.
                ticktext
                    Sets the text displayed at the ticks position
                    via `tickvals`. Only has an effect if
                    `tickmode` is set to "array". Used with
                    `tickvals`.
                ticktextsrc
                    Sets the source reference on Chart Studio Cloud
                    for `ticktext`.
                tickvals
                    Sets the values at which ticks on this axis
                    appear. Only has an effect if `tickmode` is set
                    to "array". Used with `ticktext`.
                tickvalssrc
                    Sets the source reference on Chart Studio Cloud

                    refers to the width of the plotting area only.
                y
                    Sets the y position with respect to `yref` of
                    the color bar (in plot fraction). When `yref`
                    is "paper", defaults to 0.5 when `orientation`
                    is "v" and 1.02 when `orientation` is "h". When
                    `yref` is "container", defaults to 0.5 when
                    `orientation` is "v" and 1 when `orientation`
                    is "h". Must be between 0 and 1 if `yref` is
