# Plotting plain data (single value lists) in 3D

Some Chemistry data sets

I am trying to plot some titration data with Mathematica. I have done 4 experiments and gathered around 70 pH points (one for each milliliter) during each session, and therefore I have 4 sets of pH measurements. Now, in each experiment I used a different concentration of an extra compound (something that affects the titration), so the curves should, when plotted in 3D, show a nice behavior, since the precipitant forces the protons out of the acid (the Chemistry part here; may ignore).

Now, this curves are not meant to be plotted with equals distances, as in the image and what I've managed to do.

The standard why of plotting these 4 curves is by placing them at the $\log_{10}$ of the concentration of the extra compound ($\text{CaCl}_2$ for those who might be interested). My data looks like this:

L1 = {1.63, 1.67, 1.71, 1.76, 1.80, 1.85, 1.90, 1.94, 1.99, 2.03,

12.34, 12.36}


So, each value there is the y-value, the number of item is the x-value and the z-value (or whatever it must be) is, for each complete set, the logarithm of the concentration.

Any help is appreciated!

Example (extract from L1):

L = {{1.63,0,-0.7}, {1.67,1,-0.7}, {1.71,2,-0.7}, {1.76,3,-0.7}, {1.80,4,-0.7}, {1.85,5,-0.7}}


The coordinates:

{{L3, L1, L2, L4, L5}, {Log10[0.199], Log10[0.099], Log10[0.15],
Log10[0.054], Log10[0.0265]}}

Sorry to say I don't understand this question. Could you possibly give a much smaller example of the input and output that you want? I assume a set of X,Y,Z coordinates to be plotted? –  Mr.Wizard Apr 30 at 2:52
@Mr.Wizard Hang on… –  Fiire Apr 30 at 3:00
@Mr.Wizard Is the example okay? –  Fiire Apr 30 at 3:04
The first two values seem clear now but I don't know how to calculate -0.7. Assume I know nothing about your field or process (which is probably close to correct). –  Mr.Wizard Apr 30 at 3:16
@Mr.Wizard The -0.7 is a constant that depends on the experiment. It can't be easily calculated, if not at all, from the data. i.e. it is given. –  Fiire Apr 30 at 3:21

This is not yet an answer, but rather an exploration of the question. Please tell me if this is somewhat like what you need except without a surface joining the points in the y direction (horizontally in the orientation below):

f[L_List, z_] := MapIndexed[{#, #2[[1]], z} &, L]

points = Join @@ MapThread[f, {{L1, L2, L3, L4}, {-0.7, -0.4, -0.2, 0.0}}];

ListPointPlot3D[points, BoxRatios -> 1]


@Fiire I see that you Accepted this answer. Thanks, but as it's not complete I suggest you wait. Also, you might receive a better answer from someone else. Because the points don't quite align a naive joining results in something I don't think you want:

lines = MapThread[f, {{L1, L2, L3, L4}, {-0.7, -0.4, -0.2, 0.0}}] ~Flatten~ {2};

Graphics3D[Line @ lines, BoxRatios -> 1]


Could you provide additional guidelines for how the data is to be handled? Should an attempt to align the samples be made?

Exactly that! That's what I need. –  Fiire Apr 30 at 3:45
@Fiire Okay, I'll implement that soon; right now I'm taking a break. –  Mr.Wizard Apr 30 at 3:47
It's almost how I need it. The order is supposed to be L3,L1,L4,L2. I don't know if that would be possible to add a surface, which would make the graph a little bit more readable, as for interpretation. –  Fiire Apr 30 at 15:43
@Fiire Okay, that helps. I'm still having trouble making a surface, primarily I think because the data sets are not all the same length. Is it acceptable to discard the trailing points in the longer lists? –  Mr.Wizard Apr 30 at 19:11
Yeah, I don't think they are crucial here. –  Fiire May 1 at 2:27
