Why are some plot figures not showing all lines?

Hi all,

I am plotting different data sets on 4 seperate figures. Each graph should have 9 lines of data and one 'xline'. Figures 1 and 3 work just fine, but figure 2 and 4 do not plot 3 of the 9 lines, namely the ones for the "Vulcan 4.2" types, the blue lines. I do not get any errors or anything and the code for each figure is basically the same, except for the data they are using. When looking at the variables, I can also not see any problem. FYI I use a random 'x' from one of the data sets, since these are the exact same for each one. Does anybody know what might be the reason and how to solve this? Thank you.

I attached the code, raw data and the output of the figures.

"Figures 1 and 3 work just fine, but figure 2 and 4 do not plot 3 of the 9 lines"

How are you checking this? Simply looking at a figure does not tell you how many lines are plotted on it, e.g. it will not show you if there are lines hinding under other lines, or lines with (non-plotted) NaN data. You need to check the plot objects themselves, e.g. the number of axes children or the size of the X and Y data.

For a start, show us how many children those axes have.

[Mathieu NOE]

you are displaying twice the same numerical data so colors are hidden

this comes from a mistake when you load the data , you are not reading the correct csv files

% TOF 4.2
% Vulcan421 = readmatrix("20230707_Conductex 4.2_1.csv");
% Vulcan422 = readmatrix("20230707_Conductex 4.2_2.csv");
% Vulcan423 = readmatrix("20230707_Conductex 4.2_3.csv");
Vulcan421 = readmatrix("20230707_Vulcan 4.2_1.csv");
Vulcan422 = readmatrix("20230707_Vulcan 4.2_2.csv");
Vulcan423 = readmatrix("20230707_Vulcan 4.2_3.csv");

Oh right! A simple mistake, thank you very much!
