Datapoints

• Select the shape by name you want to modify. See here to find shape names.

• Define the chart’s data under data.

• Use settings.isChartLabelValueVisible to globally enable or disable all value labels.

• Use datapoints to override that setting for specific data points.

• Each datapoint uses:

  • categoryIndex: the position of the data point on the X-axis (starting from 0).

  • seriesIndex: the index of the data series in your dataset (starting from 0).

  • isLabelValueVisible: whether the label for that specific point should be visible.
