When I select data, the "Series x Values" and Series y Values" don't show up. Only "Series Values" show up. Anyone know how to get the x values and y values options to show up?

Hi Chris, I don't suppose you'd be able to extend this example to show how to deal with uncertainties in both x and y, so you get uncertainty "boxes" rather than "bars" (as you illustrated in the "basic process" at the start of the video)? It's really hard to find any info out there on plotting uncertainties in both x and y in any software, and I'm beginning to wonder - is it really necessary? Cheers, Benson

It is all one example with uncertainties in x and y. Only two points are needed for either the maximum line or the minimum lines, and these points were obtained using both uncertainties.

Hi Chris, What I meant was, in the final Excel graph in the video, there are only error bars in y. Would you be able to add error bars in x to the example, and then show how to draw an error box or "uncertainty zone" like the sketch you've got on the right of the screen at about the 7 minute mark? Thanks! Benson

***** Thank you for your suggestion. The x error bars are simply small so it does show up on the graph. Though I could redo this, I don't think it would be the best use of my time.

Is there any rule for the number of significant digits for the uncertainty of the slopes?
@donerphysics

Slopes are division (rise/run) so we add the percent uncertainties for the numerator and denominator.

why is 3.2+0.3=3.19 for max slop x?

@@MappaPetts1999 because sqrt(10) = 3.16227766 and max slope x = (x + delta x) where delta x = abs uncertainty = 0.03 so max slope x = (sqrt(10) + 0.03) = 3.19 excel just rounded the values from 3.16 to 3.2 which is why it seemed like 3.2+0.03=3.19
