* If your experiment has many trials, you can change the refresh interval here.

## View Trial Intermediate Result Graph

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

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.

## 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.

![](../../img/webui-img/detail-local.png)
* 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.

* If you want to compare some trials, you can select them and then click "Compare" to see the results.

![](../../img/webui-img/compare.png)
* Support to search for a specific trial by it's id, status, Trial No. and parameters.

![](../../img/webui-img/search-trial.png)
* You can use the button named "Copy as python" to copy the trial's parameters.

![](../../img/webui-img/copyParameter.png)
* If you run on the OpenPAI or Kubeflow platform, you can also see the hdfsLog.
