Node-RED block in Snap4City Microservice library node-red-contrib-snap4city-developer is "get-typical-time-trends">
    <p>It allows to retrieve the typical time trends inserted.</p>

    <h3>Inputs</h3>
     <p>The node can receive a JSON with the parameters described in the Inputs section and with them generate the output JSON.
        If the values are not present in the input JSON, these are read by those in the configuration. If they are not present
        in either part, an error is generated for the necessary parameters.</p>
   

    <h3>Outputs</h3>
   
        <p> A JSON file indicating the list of a typical time trend</p>

            <span class="property-type">string</span>
        </dt>
        <dd> This is the uri of the sensor used as source of raw data. You can find type of sensor in the "Data Inspector" of Snap4city.</dd>
        <dt>valueName (optional)
            <span class="property-type">string</span>
        </dt>
        <dd> This is the name of the sensor that is also the name of the calculated value. </dd>

            <span class="property-type">string</span>
        </dt>
        <dd> The format must be this: "yyyy-mm-dd". This is the data chosen to select the period used to collect raw data from sensors. </dd>

        </dt>
        <dd> The format must be this: "yyyy-mm-dd". With reference date and number of periods we define the time interval of computations. This is the start date of the interval. </dd>
