## View Trial Intermediate Result Graph

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

We set a filter function for the intermediate result graph because that the trials may have many intermediate results in the training progress. You need to provide three data if you want to use the filter button to see the trend of some trial.

What data should be written in the first input? Maybe you find an intermediate count those trials became better or worse. In other word, it's an important and concerned intermediate count. Just input it into the first input.

After selecting the intermeidate count, you should input your focus metric's range on this intermediate count. Yes, it's the min and max value. Like this picture, I choose the intermeidate count is 9 and the metric's range is 60-80.

As a result, I filter these trials the metric's range is 20-60 on the 13 intermediate count.

## View trials status

Click the tab "Trials Detail" to see the status of the 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 in the table. If you run an experiment that final result is 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.

* You can use the button named "Copy as python" to copy trial's parameters.

* If you run on OpenPAI or Kubeflow platform, you can also see the hdfsLog.

![](../../img/webui-img/detail-pai.png)
* Kill: you can kill a job that status is running.
* Support to search for a specific trial by it's id, status, Trial No. and parameters.
