+### 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"]))]

+#### Variables in Shape Label Text
+
+*New in 5.15*
+
+Use `texttemplate` to add text with variables to shapes. `texttemplate` uses d3 number and date formatting and supports raw variables, which use the raw data from the shape definition, and some calculated variables. Add a variable with "%{variable}".
+
+This example adds the raw variables `x0` and `y0` to a rectangle and shows the calculated variables `height`, `slope`, and `width` on three other shapes. 
+
+For a complete list of available variables, see the [Shape Reference Docs](https://plotly.com/python/reference/layout/shapes/).
+
+
+```python
+import plotly.graph_objects as go
+
+fig = go.Figure()
+
+fig.add_shape(
+    type="rect",
+    fillcolor="MediumSlateBlue",
+    x0=-0.5,
+    y0=-0.5,
+    x1=1,
+    y1=1,
+    label=dict(
+        texttemplate="x0 is %{x0:.3f}, y0 is %{y0:.3f}", font=dict(color="DarkOrange")
+    ),
+)
+
+fig.add_shape(

+
+#### Variables in Shape Label Text for New Shapes
+
+*New in 5.15*
+
+Use `texttemplate` to add text with variables to new shapes drawn on the graph. This example figure is configured to allow the user to draw lines and automatically labels each line with its slope. Select **Draw line** in the modebar to try it out.
+
+```python
+import plotly.graph_objects as go
+
+fig = go.Figure(
+    layout=go.Layout(newshape=dict(label=dict(texttemplate="Slope: %{slope:.3f}")))
+)
+
+fig.show(
+    config={
+        "modeBarButtonsToAdd": [
+            "drawline",
+        ]
+    }
+)
