This posted worked well.
You can swithch between the tabs with a click to see the seasonal.
I was working on a new edition with two of your charts, plus seasonal as you did here, but I think the 2 charts are too big at the moment.
Using my photo editor, I started with a chart supposedly 132kb (in earlier test post), put two together and wound up with one at 403kb and I know not why ???
I think it will be too big.
I was going to comment to Rabbit, that I think the seasonal charts have been "right on" for Ng but was in the middle of trying to combine the charts.
We'll see what I finally get that will post.
