Thanks for the quick reply!
Let me answer the "low hanging fruit" question and make some comments:
- Are you sure you want a category line chart for your data? Ans: No, I'm not sure. This is my first graph attempt. Started a couple months ago on it and it has been a learning exercise. (not necessarily the easiest one, either!) Learning how to do something new with an app almost never is.
2.The X-axis spacing between data points is equal regardless of the number of days between them. Reply: I've been looking at the spacing between dates and you're right. However, so far, the overall graph looks good, at least until one gets to the last four data days. I've noticed this problem before, though, and as new data is added the curve tends to smooth out properly, so that is good.
3.A scatter chart is the only true X-Y chart. Reply: Thanks for the input. I think I've read this before here while trying to troubleshoot.
4.To make a scatter chart, the X and Y data must both be in normal data cells, not the X in header cells like the other charts require. And you'll have to be careful about the years associated with your dates. Reply: I like the extra input. I was worried about how the December data point would mess up the graph if I changed anything. The first CDC confirmed variant case was at the end of December and I wanted to keep it accurate. Thought I might deal with it later, if needed. The other option I was considering was covering the Dates to Julian but didn't know how that would affect anything. This graph is being shared with non-scientific-type people so K.I.S.S. is helpful. I can understand scatter diagrams but the typical lay person, probably not so much. Also, "connecting the dots" with a line shows up well, but little dots with space between them don't have as much visual impact.
With regard to editing the dates or redoing the graph, this will take a lot more work. I'm still doing battle with trying to figure out the best way to capture the Table data and put it in the graph. It's been more of a trial-and-error process. Sorry, but just not as fast of a learner as I used to be. Also, selected the wrong computer in the original post; doing this on a MBP 2012, not the MP. Geeze, almost 10 years old now!
As for doing the more difficult part now, I did go to the sidebar and check what all the dates were, and they were all the same type (unless I missed something).
"Note: All spreadsheet dates in the table’s Date column are set as numbers to Align Right, for what it's worth."
Will check this out in some more detail but that, and re-editing the Table, will take some time.
(doing this in dark-mode now ... not as easy to do)
