# Performance Charts Creation

### Creating a Performance Chart

To create a Performance chart, follow these steps:

* Navigate to the `Charts` tab in your Fiddler AI instance
* Click on the `Add Chart` button on the top right
* In the modal, Select the project that has a model with Custom features
* Select **Performance Analytics**

| Max Sample size | <p>Integer representing the maximum number of rows used for computing the chart, up to 500,000. If the data selected has less rows, we will use all the available rows with non null target and output(s).<br>Fiddler select the <code>n</code> first number of rows from the selected slice.<br><br><em>Note: Clickhouse is configured using multiple shards, which means slightly different results can be observed if data is only selected on a specific shard (usually when little observation are queried).</em></p> |

### Available in-chart controls

| Control                  | Model Task                 | Value                                                                                              |
| ------------------------ | -------------------------- | -------------------------------------------------------------------------------------------------- |
| Time range selection     | All                        | Selecting start time and end time or time label for production data. Default to last 30 days       |
| Positive class threshold | Binary classification      | Selecting threshold applied for computation / visualization. Default to 0.5                        |
| Displayed labels         | Multi-class Classification | Selecting the labels to display on the confusion matrix (up to 12). Default to the 12 first labels |

### Saving the Chart

Once you're satisfied with your visualization, you can save the chart. This chart can then be added to a Dashboard. This allows you to revisit the Performance visualization at any time easily either directly going to the Chart or to the dashboard.
