Key Features

- Show Data Table: Displays a data table alongside the chart for improved screen reader accessibility, including percentage values where applicable.
- Show Markers: For area, spline, line, and step charts, markers can be displayed at each data point to simplify value identification.
- Show 0 When No Data Available: Available for area, scatter, and column charts, this setting controls whether zero values are shown when data is missing, affecting chart continuity.
- Show Continuous Line: For area, spline, line, and step charts, this option removes gaps in the line when data points are missing, ensuring a continuous line unless zero values are shown.
- Chart Variation (Column Charts): Allows selection between stacked or side-by-side grouping of column values to suit data comparison needs.
