 Temperature History
 ===================
 
-DAMARIS automatically retrieves one temperature history for the complete experiment from the local ``tempproxy`` service at ``http://localhost:8000/v1/readings`` after the experiment finishes. The proxy controls the temperature device; no controller, serial device, or polling interval needs to be configured in DAMARIS. Successful readings are stored under the ``temperature`` DataPool key with elapsed seconds on the x-axis and the proxy's ``pv`` values unchanged on the y-axis, so units depend on the configured controller. If the proxy is unavailable or has no readings for the experiment, the history is omitted and the experiment's other data is still saved.
