#### Simple Count Hexbin
37+
38+
This page details the use of a [figure factory](/python/figure-factories/). For more examples with Choropleth maps, see [this page](/python/choropleth-maps/).
39+
40+
In order to use mapbox styles that require a mapbox token, set the token with `plotly.express`. You can also use styles that do not require a mapbox token. See more information on [this page](/python/mapbox-layers/).
41+
42+
```python
43+
import plotly.figure_factory as ff
44+
import plotly.express as px
45+
46+
px.set_mapbox_access_token(open(".mapbox_token").read())
47+
df = px.data.carshare()
48+
49+
fig = ff.create_hexbin_mapbox(
50+
data_frame=df, lat="centroid_lat", lon="centroid_lon",
51+
nx_hexagon=10, opacity=0.9, labels={"color": "Point Count"},
52+
)
53+
fig.update_layout(margin=dict(b=0, t=0, l=0, r=0))
54+
fig.show()
55+
```
56+
57+
#### Count Hexbin with Minimum Count and Opacity
58+
59+
```python
60+
import plotly.figure_factory as ff
61+
import plotly.express as px
62+
63+
px.set_mapbox_access_token(open(".mapbox_token").read())
64+
df = px.data.carshare()
65+
66+
fig = ff.create_hexbin_mapbox(
67+
data_frame=df, lat="centroid_lat", lon="centroid_lon",
68+
nx_hexagon=10, opacity=0.5, labels={"color": "Point Count"},
69+
min_count=1,
70+
)
71+
fig.show()
72+
```
73+
74+
#### Display the Underlying Data
75+
76+
```python
77+
import plotly.figure_factory as ff
78+
import plotly.express as px
79+
80+
px.set_mapbox_access_token(open(".mapbox_token").read())
81+
df = px.data.carshare()
82+
83+
fig = ff.create_hexbin_mapbox(
84+
data_frame=df, lat="centroid_lat", lon="centroid_lon",
85+
nx_hexagon=10, opacity=0.5, labels={"color": "Point Count"},
86+
min_count=1, color_continuous_scale="Viridis",
87+
show_original_data=True,
88+
original_data_marker=dict(size=4, opacity=0.6, color="deeppink")
89+
)
90+
fig.show()
91+
```
92+
93+
#### Compute the Mean Value per Hexbin
94+
95+
```python
96+
import plotly.figure_factory as ff
97+
import plotly.express as px
98+
import numpy as np
99+
100+
px.set_mapbox_access_token(open(".mapbox_token").read())
101+
df = px.data.carshare()
102+
103+
fig = ff.create_hexbin_mapbox(
104+
data_frame=df, lat="centroid_lat", lon="centroid_lon",
105+
nx_hexagon=10, opacity=0.9, labels={"color": "Average Peak Hour"},
106+
color="peak_hour", agg_func=np.mean, color_continuous_scale="Icefire", range_color=[0,23]
107+
)
108+
fig.show()
109+
```
110+
111+
#### Compute the Sum Value per Hexbin
112+
113+
```python
114+
import plotly.figure_factory as ff
115+
import plotly.express as px
116+
import numpy as np
117+
118+
px.set_mapbox_access_token(open(".mapbox_token").read())
119+
df = px.data.carshare()

122+
