+
+Colorbars can be positioned by specifying x and y coordinates. By default, the x and y values are "paper" coordinates, which refer to the plot area. You can also use coordinates based on the "container" by setting `xref="container"` or `yref="container"`. The following example uses a container reference for the x position.

+### Pattern Fills
+
+*New in 5.15*
+
+Icicle charts support [patterns](/python/pattern-hatching-texture/) (also known as hatching or texture) in addition to color. In this example, we apply a pattern to all chart sections. We also configure the `size` and `solidity` of the pattern.
+
+```python
+import plotly.graph_objects as go
+
+fig = go.Figure(
+    go.Icicle(
+        labels=["Eve", "Cain", "Seth", "Enos", "Noam", "Abel", "Awan", "Enoch", "Azura"],
+        parents=["", "Eve", "Eve", "Seth", "Seth", "Eve", "Eve", "Awan", "Eve"],
+        values=[10, 14, 12, 10, 2, 6, 6, 4, 4],
+        root_color="lightgrey",
+        textfont_size=20,
+        marker=dict(pattern=dict(shape="|", size=5, solidity=0.9)),
+    )
+)
+
+fig.update_layout(margin=dict(t=50, l=25, r=25, b=25))
+fig.show()
+```
+
 ### Set the Direction of Icicle charts
 
 As mentioned above, Icicle charts can grow in one of four directions. Icicle charts have a `tiling` attribute and this has two attributes: `orientation` and `flip`. `orientation` takes either `h` (horiztonal) or `v` (vertical) and `flip` takes either `x` or `y`. You can use these two attributes in combination to create each of the four cardinal directions: left, right, top, bottom.

+### Adding Multiple Legends
+
+*New in 5.15*
+
+By default, all traces appear on one legend. To have multiple legends, specify an alternative legend for a trace using the `legend` property. For a second legend, set `legend="legend2"`. Specify more legends with `legend="legend3"`, `legend="legend4"` and so on.
+
+In this example, the last two scatter traces display on the second legend, "legend2". On the figure's layout, we then position and style this legend to display on the right of the graph below the first legend.
+
+
+```python
+import plotly.graph_objects as go
+from plotly import data
+
+df = data.gapminder()
+
+df_germany = df.loc[(df.country.isin(["Germany"]))]
+df_france = df.loc[(df.country.isin(["France"]))]
+df_uk = df.loc[(df.country.isin(["United Kingdom"]))]
+
+

+    df.loc[(df.continent.isin(["Europe"]))].groupby(by="year").mean(numeric_only=True)
+)

+        go.Scatter(x=df_france.year, y=df_france.gdpPercap, name="France"),
+        go.Scatter(x=df_uk.year, y=df_uk.gdpPercap, name="UK"),
+        go.Scatter(
+            x=df_averages_europe.index,
+            y=df_averages_europe.gdpPercap,
+            name="Europe",
+            legend="legend2",
+        ),
+        go.Scatter(
+            x=df_averages_americas.index,
+            y=df_averages_americas.gdpPercap,
+            name="Americas",
+            legend="legend2",
+        ),
+    ],
+    layout=dict(
+        title="GDP Per Capita",
+        legend={"title": "By country", "bgcolor": "Orange",},
+        legend2={
+            "x": 1.155,
+            "y": 0.55,
+            "xanchor": "right",
+            "yanchor": "middle",

+            "title": {"text": "By continent"},
+        },
+    ),
+)
+
+fig.show()
+
+```
+
+### Positioning Legends
+
+In the previous example, we position the second legend by specifying x and y values. By default, these values are based on the width and height of the plot area. It is also possible to specify values that reference the container width and height by setting "xref=container" and "yref="container" (the default values are "xref=paper" and "yref="paper"). When set to "container", the margin grows so the legend and plot don't overlap.
+
+```python
+import plotly.graph_objects as go
+from plotly import data
+
+df = data.gapminder()
+
+df_germany = df.loc[(df.country.isin(["Germany"]))]
+df_france = df.loc[(df.country.isin(["France"]))]

+    data=[
+        go.Scatter(x=df_germany.year, y=df_germany.gdpPercap, name="Germany"),
+        go.Scatter(x=df_france.year, y=df_france.gdpPercap, name="France"),
+        go.Scatter(x=df_uk.year, y=df_uk.gdpPercap, name="UK"),
+    ],

+        title="GDP Per Capita",

+            "xref": "container",
