# joining data points - added lines

I have a set of data {x,y,stdev}, and I want to have a SINGLE line joining the data points.

Whenever I put Joined -> True while running ListLogLogPlot, I get all these extraneous lines that I'm not able to deduce where they're originating from.

data3 = {{1.25*^-7, 6.505*^-7,
9.1*^-9}, {1.2499999999999999*^-6, 0.0000598392,
8.32*^-7}, {0.000012499999999999999, 0.0021682996,
0.0000290116}, {0.000125, 0.0264216604,
0.0011165428}, {0.00125, 0.1169769169,
0.0015663171}, {0.012499999999999999, 0.4577327298,
0.0107049024}, {0.125, 1.8380050695499999,
0.074451469}, {1.25, 5.796026990950001, 0.4667664415}, {12.5,
12.6452287892, 2.9714758632}, {125., 15.167773831949999,
3.4492264127}, {2.5*^-7, 2.5947*^-6,
3.6*^-8}, {2.4999999999999998*^-6, 0.0001998515,
2.9297*^-6}, {0.000024999999999999998, 0.0051567977,
0.0000906581}, {0.00025, 0.0426349414,
0.0005633788}, {0.0025, 0.1721446492,
0.0040464007}, {0.024999999999999998, 0.664622794,
0.018272221}, {0.25, 2.66528408005, 0.114312145}, {2.5,
7.78070269025, 0.8960672623}, {25., 14.321022694500002,
3.6701272203}, {250., 18.893069122900002, 7.3919788655}};

ListLogLogPlot[{data3[[;; , 1 ;; 2]]}, Joined -> True]


When I do this, I get a plot that looks like this

And not a single line connecting the data:

How do I resolve this issue? Logically I'm not able to see where the additional Joining is coming from that's creating the extra lines.

Another idea is to use ListCurvePathPlot, especially if your curve doesn't conform to a function (i.e., there are multiple y-values for a single x-value), although you will have to work a bit to get the desired log scaling. First, here is ListCurvePathPlot on your data:

ListCurvePathPlot[data3[[All, ;;2]]]


Next, here is how to modify things to get log scaling:

ListCurvePathPlot[
Log[data3[[All, ;;2]]],
AxesOrigin -> {Log[10^-7],Log[10^-7]},
Ticks->{ChartingScaledTicks["Log"],ChartingScaledTicks["Log"]}
]


The data set is unsorted and this causes zigzags. Try this:

ListLogLogPlot[SortBy[data3[[;; , 1 ;; 2]], First], Joined -> True]


• This solved it - thank you so much! Aug 6 '18 at 0:18
• Or just ListLogLogPlot[Sort[data3[[;; , 1 ;; 2]]], Joined -> True] Aug 6 '18 at 0:22
