# Datapoints

1. Select the shape by `name` you want to modify. See [here](/knowledge-base/finding-shape-names.md) to find shape names.
2. Define the chart’s data under `data`.
3. Use `settings.isChartLabelValueVisible` to globally enable or disable all value labels.
4. Use `datapoints` to override that setting for specific data points.
5. Each datapoint uses:
   1. `categoryIndex`: the position of the data point on the X-axis (starting from 0).
   2. `seriesIndex`: the index of the data series in your dataset (starting from 0).
   3. `isLabelValueVisible`: whether the label for that specific point should be visible.
