Basic graphing: axes label and unit; add error bars; adding trendline plot Scatter 1. plot q vs. t 2. add trendline 3. add error bars t(s) q (micro C) 0 0.5 10.72 0.72 1 0.5 9.44837418 0.4 2 0.5 7.827307531 0.36 3 0.5 7.984182207 0.576 4 0.5 6.95920046 0.256 5 0.5 5.873306597 0.192 6 0.5 4.968116361 0.52 7 0.5 5.517853038 0.552 8 0.5 5.133289641 0.64 9 0.5 3.809696597 0.256 10 0.5 4.398794412 0.72 11 0.5 3.160710837 0.168 12 0.5 3.411942119 0.4 13 0.5 3.09331793 0.368 14 0.5 2.025969639 0.44 15 0.5 2.655301601 0.424 16 0.5 1.50696518 0.512 17 0.5 2.002835241 0.176 18 0.5 1.548988882 0.104 19 0.5 1.287686192 0.208 20 0.5 1.737352832 0.384 21 0.5 1.424564283 0.2 22 0.5 1.636031584 0.528 23 0.5 0.322588437 0.68 24 0.5 0.323179533 0.584 25 0.5 1.348849986 0.528 26 0.5 0.310735782 0.432 27 0.5 0.856055127 0.184 28 0.5 0.880100626 0.272 29 0.5 0.086232201 0.464 30 0.5 0.153870684 0.344 s t(s) s q (micro C) 0 5 10 15 20 0 2 4 6 8 10 12 f(x) = 12.5198577421019 exp( − 0.12359152469185 q vs.t, with error bar on bo t (s) q (micro C) 0 5 10 15 20 0 2 4 6 8 10 12 f(x) = 12.5198577421019 exp( − 0.12359152469185 q vs.t, w/o error b t (s) q (micro C)
