I just repaired a problem on the blog: when you clicked on a chart, it was no longer opening in a full-size version. The problem seems to have affected posts back to November of last year. I first became aware of it Tuesday night, 2/9, but it may have existed before that.
I’m sorry. If you are going to be able to read and understand the charts I embed in the blog, you have to be able to open them at full size.
If ever you can’t open a chart, please let me know by leaving a comment. And that goes for any other problem with the functionality of the blog.
Hopefully it is fixed now. Thanks for your understanding.
