Data points are used in line, point, lollipop, area, stream, plotted, and radar charts to indicate where the x- and y-axis values intersect. Data points can be enabled or disabled, but enabling them can make it easier to read the chart.
Data Point Style
Toggle the Data Point buttons (green highlight below) show data points in the desired style: fill, empty, or semi-filled

Tooltips for Line and Area Charts
There are 2 types of tooltips when working with line and area charts (red highlight below). The type of tooltip displayed depends on whether or not data points are enabled from the Component ribbon.
The default tooltip for these visualizations contains a title (which is the member element on x axis for the given data point) and a list for the data point; the list contains all the member elements in the legend, color coded accordingly, and the corresponding measure results from the y axis. Additional measures in the Tooltip drop zone will not be displayed. The data point being displayed in the tooltip is indicated by a vertical line (red arrow).
If Data Points are enabled from the Component ribbon, the regular tooltip will appear when hovering over the chart's data points (blue highlight below), while the line chart tooltip (described above) will appear when hovering elsewhere in the chart.
