Curve wrapping with different curve styles

Recommended Posts

A customer posted a question to our support staff: Is it possible to display wrapped curves using different line styles/fills?

While there is no way to do this automatically at this time in LogPlot7, there is a trick. It involves stacking three copies of the curve column in the log design, all with the same name (and linking to the same data column), but truncated to different data ranges and curve styles.

Please refer to the left-hand curve column in this example.

1. The red line shows Gamma values from 0 to 2000. It is defined by a Curve Column in the log design, named Gamma-Gamma, with a data range from 0 to 2000. The Appearance/Wrap settings are set to Truncate. It's set up as a line curve, color red, no fill. This column is the lowest in the stack (you can use the Send to Back option in LogDesign).

2. The gray portion shows Gamma values from 2000 to 4000. It is defined by a Curve Column in the log design, also named Gamma-Gamma, with a data range from 2000 to 4000. The Appearance/Wrap settings are set to Truncate. It's set up as a filled curve, with both line and fill color = gray. This column is the middle one in the stack.

3. The black portion shows Gamma values from 4000 to 6000. It is defined by a Curve Column in the log design, named Gamma-Gamma, with a data range from 4000 to 6000. The Appearance/Wrap settings are set to Truncate. It's set up as a filled curve, with both line and fill color = black. This column is the top one in the stack.

For reference you will see a blue curve column showing the same data with no wrapping (column range = 0 - 6000), and a green curve column showing automatic wrap.
