Graphing with JSON

If you query a Datadog timeboard though the dashboard API, the result is a JSON object with the following layout:

    "type": "object",
    "properties": {
        "title": {"type": "string"},
        "description": {"type": "string"},
        "layout_type": {"enum": ["ordered", "free"]},
        "is_read_only": {"type": "boolean"},
        "template_variables": {"type": "array", "items": TEMPLATE_VARIABLE_SCHEMA},
        "notify_list": {"type": "array", "items": {"type": "string"}},
        "widgets": {
            "type": "array",
            "items": WIDGET_SCHEMA
    "required": ["title", "layout_type", "widgets"],

Template variable schema

Dashboard template variables apply a new scope to one or more graphs on your dashboard. This allows you to dynamically explore metrics across different sets of tags by using variables instead of specific tags. To configure them through the Dashboard API, use the following layout:

    "type": "object",
    "properties": {
        "name": {"type": "string"},
        "default": {"type": "string"},
        "prefix": {"type": "string"},
    "additionalProperties": false,
    "required": ["name"]
namestringName of your template variable.
defaultstringDefault value for your template variable.
prefixstringTag key for your template variable.
