This type of thing could happen if the data that was used was not valid. As a test of this you can try to create a static chart with data inputed from the wizard to see if it will display like that. If you can get it working like that it would indicate a problem with the data of some type.
If it does the same thing then you may be experiencing some other issue with the tool. Please give this a try and let us know what the results are.
