Oriana 4 FAQs

Raw data plots have more than one observation per symbol

Q. My raw data plots are sometimes plotting more than one observation per symbol, with a note at the bottom saying that a single symbol equals (for example) three observations. How do I get it do do just one symbol per observation?

A. By default each symbol does equal one observation. However, if there is not enough room to fit all the required symbols for each observation Oriana will switch to having each symbol represent a multiple of observations. You can try to fix this with one or more of the following steps:

  • Reduce the size of the symbols on the Symbols page of the graph dialog box
  • Switch to using a different type of raw plot (e.g. from points arranged margin inwards to margin outwards)
  • Adjust the Basal Circle option on the Axes page to make it smaller (for margin outwards and center outwards graphs only).
  • Increase the overall size of the graph by making the graph window and/or the whole Oriana window bigger.

Correctly displaying trend/bidirectional data

Q. My data are "trend" data as opposed to vector-type directional data - I record them as "north-south" as opposed to either "north" or "south." When I do a rose diagram only half the compass is shown. How do I get it to cover the full compass, with half being the mirror image of the other?

A. With this type of data you should set the variable type to be "Axial" rather than "Angles". Oriana will then automatically treat the data as bidirectional in all graphs and analyses. You can change the variable type through the Data|Change Variable Type option, or by using the drop-down boxes at the top of the data editor.

Entering tabular/frequency data

Q. How can I analyse data which is in the frequencies within each compass seqment are summarised, e.g. data in the following format:

Angle No. of animals
10 5
20 13
30 1
etc.  

A. After setting up a new file choose the Data|Edit Frequencies command. This lets you enter data in exactly this format.

Graph doesn't import correctly into Corel Draw

Q. When I try to import my Oriana graphs as metafiles (WMF or EMF files or through the clipboard) into Corel Draw they are not displayed properly, or an error message is given. What is wrong?

A. A metafile is basically a collection of instructions for how to draw the lines, circles, boxes, text, etc. that make up an image. When metafiles are imported into vector drawing programs like Corel Draw the drawing program must convert these instructions to its own internal format. Often the program can misinterpret the instructions, or simply cannot reproduce the instruction in its internal format. One common example is with text that has been rotated rather than being displayed normally along the horizontal. Some programs don't allow rotated text and others can get confused with the direction of rotation.

To test how well your drawing program does at importing metafiles please try out the test files at the Companion Software website. It provides a WMF file you can import, plus a Windows Clipboard file (.CLP file) that shows exactly what it should look like.

In our experience Corel Draw has various problems with importing metafiles, and the problems often change with each new version. There is a known problem with Corel versions 8 and 10 where Oriana graphs that have a main title at the top either give an error message or only import the title itself when imported. These same graphs can be imported to other programs (including the older Corel Draw 7 and the current version 12) with no problem.

To fix this problem simply remove the main title from the Oriana graph before exporting or copying to the clipboard. You can do this by removing the tickmark before the Main Title option on the Titles page of the Oriana Graph dialog (show either when first creating the graph or when Graphs|Edit Graph is chosen). You could also consider upgrading to the latest version 12 of Corel Draw.

If you find other problems with importing files into a vector graphics program then you can try the following suggestions:

  1. If you are exporting the graph from Oriana to an enhanced metafile (.EMF) file then try it as an older format WMF metafile to see if that works better. Similarly, if you have problems with a WMF file then try EMF.
  2. If neither work then try using the Windows Clipboard to transfer the graph. In Oriana use the menu option Edit|Copy when the graph window is visible and topmost to place it on the clipboard, then switch to the drawing program and use Edit|Paste to paste it in.
  3. If that doesn't work, and the drawing program has a Edit|Paste Special command, then use that to try and paste it with different formats.
  4. Try importing or pasting the graph into another drawing program, then exporting or copying it to your main drawing program. Note that Microsoft Word can be used as an intermediary program if you do not have another drawing program.
  5. Try making modifications to the Oriana graph, such as removing the title or changing the fonts. Also try making the graph window as large as possible before exporting/copying the image. Some problems with other programs are due to the scaling and size.

Working with more than one data file

Q. I want to compare two data files but Oriana only seems to let you have one data file open at a time. How can I have two files open?

A. Simply start up a second copy of the Oriana program and load the second file in that one.

I get an "Action canceled!" error when trying to view the help file

Q. When I try to view the help file I get a message saying "Action canceled! Internet Explorer was unable to link to the web page you requested". How can I get it to work?

A. This is caused by a security update released by Microsoft in 1995. Basically, this stops compiled HTML help files from being displayed if they are run from the Internet or over a network. Help files installed on your local hard disk will still work OK.

If you run Oriana once with administrator privilages then this should fix the problem. If not then you can fix this by having the administrator of your computer make some changes to the Windows registry. The changes to be made are described at the Microsoft Knowledge base, article 896358. There is also a free utility called HHReg that automates the process.
