# Dynamic chart

1. Select the shape by `name` you want to modify. See [here](/knowledge-base/finding-shape-names.md) to find shape names.
2. You can add additional series to a chart by specifying new series keys in your payload.
   1. Any newly added series will be created as a copy of the last existing series.
3. If your `template` contains more series than the provided data, the extra series will be automatically removed.
4. Axes that no longer contain any data after this adjustment will also be deleted.
