View summary page
-----------------

Click the tab ``Overview``.

   :target: ../../img/webui-img/refresh-interval.png
   :alt: refresh




* You can review and download the experiment results(``experiment config``, ``trial message`` and ``intermeidate metrics``) when you click the button ``Experiment summary``.

   :target: ../../img/webui-img/summary.png
   :alt: summary



* You can change some experiment configurations such as ``maxExecDuration``, ``maxTrialNum`` and ``trial concurrency`` on here.


.. image:: ../../img/webui-img/edit-experiment-param.png
   :target: ../../img/webui-img/edit-experiment-param.png

* You can click ``About`` to see the version and report any questions.

View job default metric
-----------------------


* Click the tab ``Default Metric`` to see the point graph of all trials. Hover to see its specific default metric and search space message.


.. image:: ../../img/webui-img/default-metric.png
   :target: ../../img/webui-img/default-metric.png

* Click the switch named ``optimization curve`` to see the experiment's optimization curve.

View hyper parameter
--------------------

Click the tab ``Hyper Parameter`` to see the parallel graph.


* You can ``add/remove`` axes and drag to swap axes on the chart.
* You can select the percentage to see top trials.

View Trial Duration
-------------------

Click the tab ``Trial Duration`` to see the bar graph.

View Trial Intermediate Result Graph
------------------------------------

Click the tab ``Intermediate Result`` to see the line graph.

   :target: ../../img/webui-img/trials_intermeidate.png
   :alt: trialIntermediateGraph



The trial may have many intermediate results in the training process. In order to see the trend of some trials more clearly, we set a filtering function for the intermediate result graph.

You may find that these trials will get better or worse at an intermediate result. This indicates that it is an important and relevant intermediate result. To take a closer look at the point here, you need to enter its corresponding X-value at #Intermediate. Then input the range of metrics on this intermedia result. In the picture below, we choose the No. 4 intermediate result and set the range of metrics to 0.8-1.

   :alt: filterIntermediateGraph



View trials status
------------------

Click the tab ``Trials Detail`` to see the status of all trials. Specifically:


* Trial detail: trial's id, trial's duration, start time, end time, status, accuracy, and search space file.


.. image:: ../../img/webui-img/detail-local.png
   :target: ../../img/webui-img/detail-local.png
   :alt: detailLocalImage



* The button named ``Add column`` can select which column to show on the table. If you run an experiment whose final result is a dict, you can see other keys in the table. You can choose the column ``Intermediate count`` to watch the trial's progress.


.. image:: ../../img/webui-img/addColumn.png
   :target: ../../img/webui-img/addColumn.png
