You are correct. If you want the columns stacked you will need to group the data - or rather, you should skip steps 8 and 9 where you ungroup the data. Does this work OK for you?

In regard to the data not displaying at zero degrees (North)... this is a bug. To force the columns to display at zero degrees, perform the following:
1. With the graph active, select Format:Layer.
2. Select the (Plot Details) Display tab.
3. In the Data Drawing Options group, clear the Clip Data to Frame check box.
4. Click OK to close the dialog box.

Note: I will add your name and increment the number of customers who have reported this bug. It should be fixed in a future version of Origin. You will be contacted if a version becomes available with this fix.

Thank you for the note. I have made the wind rose and am almost there. The two remaining problems I have not been able to work out are;

- the bars will not stack unless you group the data sets. This does not seem to be too much of a problem but is different from your suggestions, Nornally the bars are stacked to prevent data from being hidden.

- The data in the North Direction does not show up??? I have tryed varying orientations of the plot and other parameters and i can not figure out why it will not work. Can send example plot by email if it would help get input.

Thank you very much for getting me started in the correct direction!!
