============
1D Histogram
============

Histogram on a regular one-dimensional grid.

The x-axis defines the bin edges. As illustrated in this example,
the bin widths are not necessarily identical.

.. code::

  @NX_class = "NXroot"
  @default = "scan1"
  scan1:
    @NX_class = "NXentry"
    @default = "data"
    data:
      @NX_class = "NXdata"
      @axes = ["x"]
      @signal = "y"
      x: NX_INT64[8]
      y: NX_FLOAT64[7]

Explanation:

1. ``@axes`` has one value which corresponds to the signal rank of one.

2. ``y`` is the default signal to be plotted versus ``x``.

3. ``x`` has one more value than ``y`` since it contains the bin edges.
