# What's new in Sigma

> Sigma release notes for Sep 29, 2023: New teams endpoint, cartesian chart default value formatting, and more.

## API

### New teams endpoint

```
GET /v2/teams/{teamId}/members
```

Returns a list of team members and can be used to identify team admins.

For more information, see [Team API](https://docs.sigmacomputing.com/api/v2/#tag--teams).

## Workbook elements

### Cartesian chart default value formatting

Cartesian charts (bar, line, area, scatter, box, and combo) now display the value axis and data labels with metric abbreviations or SI units when the **Automatic** format option is applied by default or through manual selection. For example, the value 10,000,000,000 is displayed as 10B. However, if a chart's source element uses a specific format (number, currency, financial, etc.), the **Automatic** option inherits the source format.

### Y-axis in KPI chart trend lines

KPI chart trend lines can display y-axis grid lines and value labels. To enable the y-axis, go to **Element format** > **Trend** and select the **Show y-axis** checkbox.

For more information about formatting KPI chart trend lines, see [Build a KPI chart](https://help.sigmacomputing.com/docs/build-a-kpi-chart).

### Option to sort null values first or last

When sorting a table column, you can force nulls to be ordered first or last regardless of the selected sort order (descending or ascending). To customize null value sorting, right-click the column header and select **Custom sort**, then select an option in the **Nulls** field.

**Nulls** field options:

|             |                                               |
| :---------- | :-------------------------------------------- |
| **Default** | Orders nulls based on the CDW or DBMS method. |
| **First**   | Orders nulls at the top of the column.        |
| **Last**    | Orders nulls at the bottom of the column.     |
