+## Chart :fire::fire: **[ HOTNESS ALERT ]**
+
+Chart API returns distribution of a numeric column in a table
+
+It comes in three flavours
+
+1. Chart : With min, max, step in query params :fire::fire:
+
+This API returns the number of rows where amount is between (0,25000), (25001,50000) ...
+
+```

+    "_count": 124

+    "_count": 30

+  },
+  {
+    "amount": "125001 to 150000",
+    "_count": 0
+  }
+]
+
+```
+
+2. Chart : With step array in params :fire::fire:
+
+This API returns distribution between the step array specified
+
+```
+/api/payments/chart?_fields=amount&steparray=0,10000,20000,70000,140000
+
+Response

+  },
+  {
+    "amount": "70001 to 140000",
+    "_count": 12
+  }
+]
+
+
+```
+
+3. Chart : with no params :fire::fire:
+
+This API figures out even distribution of a numeric column in table and returns the data
+
+```
+/api/payments/chart?_fields=amount
+
+Response
+[
