6.14 Windrose Graph

Summary

Windrose graphs are used to present wind speed data and wind direction data collected over time at a particular location. This tutorial will demonstrate how to create windrose graphs from both raw and indexed data:

Minimum Origin Version Required: Origin 9.1 SR0

What will you learn

This tutorial will show you how to:

  • Create a windrose graph from binned data
  • Customize the direction tick labels on the windrose graph
  • Create a windrose graph from raw data

Steps

This tutorial is associated with <Origin EXE Folder>\Samples\Tutorial Data.opj.
Also, you can refer to this graph in Origin Central. (Select Help: Origin Central menu or press F11 key , and then open Graph Sample: Specialized Graphs)

Part 1: Create a Windrose Graph from Binned Data

  1. Open Tutorial Data.opj and browse to the Wind Rose folder in Project Explorer (PE).
    (If you don't have the project file, please import the sample data from here).
  2. Activate the Book6E workbook. Highlight all worksheet columns and click the Wind Rose - Binned Data button on the 2D Graphs toolbar as shown below or select Plot: Specialized: Wind Rose-Binned Data from the main menu.

    The wind rose graph should look like the following image:

  3. To change the wind direction to show only N,E,S,W double-click on the angular axis (the outermost ring) to open the Axis dialog box. Go to Scale tab and choose Angular axis in the left panel. Under Major Ticks section, set Type to By Increment and Value to 90

Part 2: Create a Windrose from Raw Data

  1. Go to the project folder Statistical and Specialized Graphs: Specialized: Wind Rose and activate the Book7E workbook, Raw Data worksheet. (If you don't have the project file, please import the sample data from here).
  2. Highlight columns A & B. Click the Wind Rose - Raw Data button on the 2D Graphs toolbar as shown below or select Plot: Specialized: WindRose - Raw Data from the main menu.
