Strip lines, or strips, are horizontal or vertical ranges that shade the background of a chart in regular or custom intervals. You can use strip lines to:

  • Improve readability for looking up individual values on the chart.

  • Separate data points when reading the chart.

  • Highlight dates that occur at regular intervals, for example, to identify weekend data points.

  • Highlight a specific key range of data.

  • Add a threshold line at a specific constant value.

A single StripLine object can either be drawn once, or repeatedly, for a given interval. This action is controlled by the Interval property. When a value of -1 is assigned to the Interval property, one strip line will be drawn. When a non-zero value is assigned to the Interval property, a strip line will be drawn repeatedly at each given interval. The location where a strip line is drawn is also affected by the IntervalOffset and IntervalOffsetType properties of the strip line.

Strip lines are always associated with an Axis object. They can be added at both design time and run time.

To add a horizontal or vertical line to display a threshold, set the StripWidth property to a value of 0.0. This will result in a line being drawn. You can use the BorderColor, BorderDashStyle and BorderWidth properties for the color, width and style of the line. No chart background properties (Back*) are used when the StripWidth property is set to 0.0.

Use the Text property of the strip line to associate text with a strip line. The placement and orientation of this text can be controlled by the TextAlignment property.

When multiple strip lines are defined for the same axis, it is possible that the strip lines will overlap. The Z-order of StripLine objects is determined by their order of occurrence in the StripLinesCollection object. This means that the first occurrence is drawn first; the second occurrence is drawn second, and so on.

Strip lines are not supported for the following chart types: Pie, Doughnut, Funnel, Pyramid, Kagi, ThreeLineBreak, PointAndFigure, Polar and Radar.

The following code example demonstrates three applications of strip lines. First, horizontal strip lines are added at recurring intervals. Second, vertical strip lines are added to highlight weekend data points. Lastly, a non-recurring strip line is added to denote the mean of the data points in the first series of the chart.

No code example is currently available or this language may not be supported.
