+
+**Description**
+
+Tile displaying data in the form of horizontal bar charts. Each cart may
+consist of one or more series of data - in the latter case, such bars are
+grouped respectively. There are no "hard" limits when it comes to the number of
+charts/series, although we suggest to keep them down to 3 charts of 2 series
+each.
+
+**Content**
+
+::
+
+  data = {
+      "title": "<title>",
+      "subtitle": "<subtitle>",
+      "ticks": ["<label1>", "<label2>", "<label3>" ...],
+      "series_list": [[<val1>, <val2>, <val3>, ...],
+                      [<val1>, <val2>, <val3>, ...]]
+  }
+
+where:
+
+.. describe:: title, subtitle
+
+   Title and subtitle displayed on the top of the tile.
+
+.. describe:: ticks
+
+   Labels to be displayed on the left side of the charts.
+
+.. describe:: series_list
+
+   List of series, as name suggests. ``[[1, 2]]`` will give one chart of two
+   bars, ``[[3, 4, 5], [6, 7, 8]]`` will give two charts of three bars each.
+
+Example::
+
+  curl http://localhost:7272/api/v0.1/<api_key>/push
+       -X POST
+       -d "tile=bar_chart"
+       -d "key=<tile_id>"
+       -d 'data={"title": "The A-Team",
+                 "subtitle": "Velocity (Last tree sprints)",
+                 "ticks": ["n-2", "n-1", "Last (n)"],
+                 "series_list": [[49, 50, 35], [13, 45, 9]]}'
+
+**Configuration**
+
+This tile does not offer any configuration options.
+
+.. note::
+
+   In case of displaying more than one charts on the same tile, the number of
+   values in ``series_list`` for every chart should be the same (and they
+   should be equal to the number of ``ticks``.
