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 Learning Center. (Select Help: Learning Center 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.

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.

  3. Do the same operations as the step 3 in the Part 1 to move the radial axis to the left-bottom. And, go to Tick Labels tab for Radial Outer 2 to remove the Suffix "%" for the radial axis tick labels.
  4. Do the same operations as the step 4 in the Part 1 to change the fill color for the stacked bars.
    The final graph should resemble the image shown below:
