+Configuration
+=============
+
+Configure KPIs
+~~~~~~~~~~~~~~
+
+#. Access `Dashboards > Configuration > KPI Dashboards > Configure KPI`
+#. Create a new kpi with widget `altair`
+
+You need to define a function like::
+
+    import pandas
+    import altair
+
+
+    class Kpi(models.Model):
+        _inherit = 'kpi.kpi'
+
+        def test_demo_altair(self):
+            source = pandas.DataFrame(
+                {
+                    "a": ["A", "B", "C", "D", "E", "F", "G", "H", "I"],
+                    "b": [28, 55, 43, 91, 81, 53, 19, 87, 52],
+                }
+            )
+            chart = altair.Chart(source).mark_bar().encode(x="a", y="b")
+            return {"altair": json.loads(chart.to_json())}
+
+
+You can use `code` in a similar way, as `pandas` and `altair` are already defined
+when using `code` on an `altair` widget.
+
