I've bought new stainless steel thermos, which are advertised to "Keeps Hot to 14Hrs".
They arrived yesterday, so I'm just testing them (I've got a funeral 4 hours away next Monday, so I'd like hot coffee available for 12 hours t cover driving there and back).
Pour boiling water in, measure it with a thermocouple, check every hour till I go to bed.
I end up with values that end up like this:
Hours C
0.00 93
1.00 91
2.00 88
3.00 86
4.00 82
6.00 78
7.00 75
9.50 70
14.00 63
16.00 60 All I want is a simple scatter chart, with hours as X axis, and degrees C as Y ... a "best fit" trend line would be nice, but I have a red biro so it's not essential (that's the Advanced Version).
Can I persuade it to do that? It seems not. I've now got a YouTube video to watch which promises to show me how, but ... the amount of time I've wasted on this this morning, I could have used an SQL DB, the Chart Control and banged out a documented, GIT based WinForms app and still had time for another coffee ... 
Heck in the four minutes the YouTube video runs, I could have chucked together an undocumented Winforms app with the Chart control and a fixed set of values. Maybe I will. Maybe I'll just seethe a bit instead, and post the CCC ...

That is to allow other people to make youtube videos about it. All that for the sake of letting you drink more coffee while watching for youtube videos on a monday morning

I've already watched one - but that was ThisOldTony on making a square rotary broach.
Good video, but not relevant to charting, I'm glad to say!

I dont know if Im missing the point
I pasted the values into a sheet, went to insert|chart
picked scatter
and it was there - Id post a pic if I knew how
Running Version: 6.3.3.2 (x64) if that helps
maybe not as pretty as excel, but it will do

Online service (i.e. Imgur) and then link here as CPallini made a couple of messages above yours

Thank you - Id always assumed you would need to sign up for such a service

At least before it wasn't... not sure now though

1. Take a photo.
2. Copy it to your computer.
3. Import it into Libre Impress.
4. Take a screenshot.
5. Paste the screenshot into IrfanView.
6. Save it as a jpg or png file.
7. Upload it to Imgur.
8. Post the address here.

Well, you could also add:
3.1 Save the presentation as PDF.
3.2 Open the PDF file.
But I didn't want to unnecessarily complicate things.

If you put boiling water in, shouldn't the first reading say 100C?
When my father went hunting he always rinsed the thermos with boiling water before pouring the coffee in. To make it last one more hour.

In theory, yes - but we aren't at sea level (which means the temperature at which water boils is lower), the atmospheric pressure is low today (ditto), kettles don't "boil" water anyway.
And most important of all, it's a cheap thermocouple (or thermistor, I'm not sure which)...

But you aren't at 8000 ft either.  I doubt you're even at 800 ft.
And while 1000 mB (at sealevel) is slightly less than 1013 I don't think it affects the boiling temperature even noticably.

Oh, that's definitely affecting the reading quite a bit, but if it's six degrees off you should consider buying a new one.

Assuming you just dumped water from your kettle directly into the bottle I also suspect a burst of rapid heat loss as the interior of the bottle is warmed from room temperature is probably a bigger factor than anything short of possible measurement error in your thermometer.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

General answer to all of LiberO:
Because it is developed by software developers. Alone, in isolation. Their only contact with Real Users of the products is indirect: Real Users have contact with developers of commercial products, LiberO developers look at commercial products trying to determine how they convey the Real Needs of Real Users.
Developers of development tools are their own Real Users, knowing their own needs and requirements. So non-commercial, open software development tools are generally high quality. For most kinds of tools not related to software development, the situation is like for Liber0: The developers are just guessing what to develop, which qualities to provide.
I never regretted spending money on commercial office packages, sound editors, video editors, 3D drawing systems, sound encoders, ... Software that is developed by software developers in cooperation with Real Users.

Gawd, I know it was a stupid thing to do, but I just downloaded and installed it.
• Install on a VM that has office 2010 (the highest I will ever go)
• OK, so "Run RH2 when I click Finish", checked.
• Click finish.
• It doesn't run. I Should have known better.
• Because it's ms bloatware, give it five times as long as I would give any other company (except adobe), then give up and open Word.
• It displays a full-window clipart-ish picture, and starts playing f***cking music! Really loud, elevator music!
(It's already got me swearing, and I haven't even opened the f***ing thing, yet!)
• The only way to stop the music appears to be by locating and clicking the "Play" button, which is as small as they can make it, with a caption font-size big enough to read.
• However, I note that there's a "settings" icon, and click it. The music stops.
• No "Shut this f***ing music up!" option. In fact, the only option is to allow them to slurp data, which is on, by default.
• Select "Go f*** yourselves"1, and exit "setting" (singular).
(1 artistic license)
• The music starts again.
• Click the loudspeaker icon, which, thankfully, gives me an option to mute the music.
• Close and re-open RH2 and Word, to see if the mute option sticks. It doesn't.
• Click the Play button,
• A really dire comic strip is displayed, which scrolls ridiculously slowly (seriously, you'd need a reading age of minus 5 to keep up).
• Ignore the stupid comic-strip intro, and just click anything that will advance the process.
• The full-window clipart-ish picture disappears, and Word's title-bar (Yes, I've re-implemented them) reads "Document1 - Microsoft Word (Not Responding)"
• Three minutes later (with a quad-core, sh1t-off-a-shovel chip and a 4-gig graphics card), Word goes full-screen with a read-only document, telling me to change the font for the whole document from comic sans to calibri (neither of which I would ever use, but there you go).
• Change the Normal style font to calibri (which I can do quickly and efficiently, because I have toolbar buttons).
• It makes a REALLY LOUD "victory" sound! Seriously, I cannot stress how f***ing loud this noise is! A guy three offices down had a heart attack!
• Minimise word, to add the above entry, but find that the "Hyuk hyuk! Y'all did it!" pop-up (I paraphrase, to imply the correct tone) is set to stay at the top of the Z-order, so I have to dismiss it before I am allowed to do anything else.
• Another mindless, and mindlessly slow scrolling, comic strip, that I scroll past in total ignorance of (and lack of interest in) its content.
• Click to go to the next task.
• ...
Microsoft Word has stopped working
Yup.

I confess that I was happier with it after it crashed.
