Customizing Lines and Data Points in a Line Chart

You can customize the lines in a line chart to show only lines, only data points, or both.

Data points represent series values for each category on the Y-axis. You can show special data markers that represent statistically significant values, such as open, high, low, and close values.

You can also change the shape of the line that connects the data points to one of the following:

Point to Point shows data points connected by straight lines.
Step at Point shows data points connected by steps that start and end at the data points.
Step Between Points shows data points connected by steps that start and end between the data points.
Smooth shows data points connected by smooth curves.

You cannot show data points if the configuration of the line chart (Series type) is set to Stacked or Stacked 100%.

Procedure

Select the line object.
To select whether to show only the line, the line and data points, or only the data points, in the Properties pane, under General, select an option in the Line display type list.
To show special data markers, click Value markers. Select the check box for the special data markers that you want to add and for each marker, specify the color and shape.
The options you specify in Value markers overwrite the options for Line display type.
To change the shape of the line that connects data points, select an option from the Line shape list.
To change the color of the lines or data points, click Palette.
