Spiral Bar Chart 01.png

Spiral Bar Chart plots time-based data as bars along an Archimedean spiral. It begins at the center of a spiral and then progresses outwards.

Data Requirements

Select one X with one Y column. The X column is mostly Time/Date data, plotted as a spiral axis; and the Y column is plotted as bars based on the spiral axis.

Creating the Graph

Select required data.

From the menu, choose Plot > Bar, Pie, Area: Spiral Bar Chart.


SpiralBar.OTPU (installed to the Origin program folder).


Spiral Bar Charts are ideal for showing large data sets, usually to show trends over a large time period.

To plot all these data points, you can decide which layout should be used to arrange the points:

  • By Period: Plot the data points as periodic patterns. Color can be assigned to each period to break them up and to allow some comparison between each period.
  • By Windings: Plot the data points on several windings, each winding share same color fill.

You can go to the Spiral tab of Plot Details dialog to do further customizations.
