Highlight chart data by adding strip lines in a paginated report (Report Builder)
Applies to: 
Microsoft Report Builder (SSRS)
Power BI Report Builder
Report Designer in SQL Server Data Tools
Strip lines, or strips, are horizontal or vertical ranges that shade the background of the paginated report chart in regular or custom intervals. You can use strip lines to:
Improve readability for looking up individual values on the chart. Specify strip lines at regular intervals to help separate data points when reading the chart.
Highlight dates that occur at regular intervals. For example, in a sales report you might use strip lines to identify weekend data points.
Highlight a specific key range. Using the previous example, you can use one strip line to highlight the highest range of sales that is between $80-100.
Strip lines are not applicable to Shape or Polar chart types.
Note
You can create and modify paginated report definition (.rdl) files in Microsoft Report Builder, Power BI Report Builder, and in Report Designer in SQL Server Data Tools.
To display interlaced strip lines at regular intervals on a chart
To show horizontal strip lines, right-click the vertical chart axis and click VerticalAxis Properties.
To show vertical strip lines, right-click the horizontal chart axis and click Horizontal Axis Properties.
Select the Use interlacing option. Grey strip lines will appear on your chart.
(Optional) Specify a color for the strip lines using the adjacent Color drop-down list.
To display interlaced strip lines at custom intervals on a chart
To show horizontal strip lines, right-click the vertical chart axis and click VerticalAxis Properties.
To show vertical strip lines, right-click the horizontal chart axis and click Horizontal Axis Properties.
The axis properties are displayed in the Properties window.
In the Appearance section of the Properties pane, for the StripLines property, click the Edit Collection (...) button to open the ChartStripLine Collection Editor.
Click Add to add a new strip line to the collection.
Click StripWidth to specify the width of the strip line, measured in inches on the report. If you are highlighting dates or times, click StripWidthType and select a time interval.
Type a value or expression for the Interval to specify how often the strip line will repeat. For example, if you specify an interval of 10, and your strip line width is 5, strip lines will display at values of 0 to 5, 15 to 20, 30 to 35, and so on.
Note
By default, Interval is set to Auto, which means the chart will not calculate an interval for custom strip lines. The chart only calculates intervals for strip lines if an interval value is set.
