+### Text on 2D Histogram Points
+
+
+In this example we add text to 2D-Histogram points. We use the values from the `z` attribute for the text, adding them following the format **%{variable}**.
+
+```python
+import plotly.graph_objects as go
+from plotly import data
+
+df = data.tips()
+
+fig = go.Figure(go.Histogram2d(
+        x=df.total_bill,
+        y=df.tip,
+        texttemplate= "%{z}"
+    ))
+
+fig.show()
+```
