Html not converting to pdf in Acrobat

Here are screen shots, one of the whole and one at the cut off right edge. What's there is correct. This is Windows 10 on a big PC and Acrobat CC. I can't find the version.  I attach the first part of the  disk file. This is the "Enterprise version" I get as a facultry of the University of Illinois. The whole think is absolutely gigantic. Photoshop works fine on truly gigantic files (>150 megapixel) in multiple layers, albeit like a snail (it refuses to use my GPU).

I tried different settings, including default font size. I think the photos are at 8. It won't let me use 7.  I tried using the scale to fit width and that did't do anything.

There is also a similar file that is 36000 pixels wide. The boxes that go to 26000 or wso on this just go to 36000. It looks OK when rescaled down a bit in browsers ... or even on Acrobat's display of the part that works.

I'll try attaching the html file ... I can't give a URL ... that's the problem! Neither web page site I'm currenly using will allow me to upload html files. The previous site did. I'm trying to convert the file on my computer. The web site on my computer, locally, works fine with this file as html in what I think is called an iframe. I managed to attach the html file here after renaming it to .txt, which of course html is! I don;t know if its ASCII or Unicode ... there are no unicode characters that I installed. Its nicely human readable, that's just what my VBA code for Excel generates. I should add that the data on the chart is public, with full permission of the people involved.
