I can't answer PM's. Sorry. Don't have a paid sub.
Might best search and find Augie's instructions from a couple days ago about posting charts.
Once you get that down, it's second nature, a piece of cake, nothing to it.
Then, once you're looking at the little URL thing all nice and pasted in b/w "charts" on the little screen just like I'm typing on right now, just delete a couple numbers and add in the ones you want. View the graph in the "Preview" screen.
