VisualDL is a visualization tool designed for Deep Learning. VisualDL provides a variety of charts to show the trends of parameters. It enables users to understand the training process and model structures of Deep Learning models more clearly and intuitively so as to optimize models efficiently.
Currently, VisualDL provides seven components: scalar, image, audio, graph, histogram, pr curve, ROC curve and high dimensional. VisualDL iterates rapidly and new functions will be continuously added.

HyperParameters visualize the relationship between hyperparameters and model metrics (such as accuracy and loss) in a rich view, helping you identify the best hyperparameters in an efficient way.
### Record Interface
The interface of the HyperParameters is slightly different from other components'. Firstly, you need to use the `add_hparams` to record the hyperparameter data(`hparams_dict`) and specify the name of the metrics(`metrics_list`). Then, for the metrics you just added, you need to record those metrics values by using `add_scalar`. In this way you can get all data for HpyerParameters Visualization.
| hparam_dict | dict | name and data of hparams. |
| metric_list | list | The metrics name to be recorded later corresponds to the `tag` parameter in the `add_scalar` interface, and VisualDL corresponds to the indicator data through the `tag`. |
| walltime | int | Record the time stamp of the data, the default is the current time stamp. |
### Demo
The following shows an example of how to use HyperParameters component, and script can be found in [HyperParameters Demo](https://github.com/PaddlePaddle/VisualDL/blob/develop/demo/components/hparams_test.py)
```python
fromvisualdlimportLogWriter
# This demo demonstrates the hyperparameter records of two experiments. Take the first
# experiment data as an example, First, record the data of the hyperparameter `hparams`
# in the `add_hparams` interface. Then specify the name of `metrics` to be recorded later.
# Finally, use `add_scalar` to specifically record the data of `metrics`. Note that the
# `metrics_list` parameter in the `add_hparams` interface needs to include the `tag`
- The table view can be displayed in a sorted order.
- Trial ID represents a specific experiment name, the column name displayed in other normal fonts is the hyperparameter name, and the column displayed in bold font is the metric name.
- The position of hyperparameters and metrics can be customized by dragging.
- The column width of the table view can be adjusted by dragging.
- You can click to expand to view the scalar of the metrics.
