For the parallel coordinate diagram of matlab, this diagram contains many lines. I want to change the width of only one line to make it wider. How can I write the code?

Thanks you!

For example, I want to change the width of the line marked by the red arrow. How should I write the code? I've been thinking for a long time, but the problem has not been solved!

load patients

tbl = table(Diastolic,Smoker,Systolic);

p = parallelplot(tbl)

在 MATLAB Online 中打开

Separate the data into two groups as follows:

Age = randi(50,[100,1]); % Random data

Height = randi(180,[100,1]); % Random data

Weight = randi(100,[100,1]); % Random data

X = [Age Height Weight];

bins = {'normal','thick'}; % Two groups of data

Nselect = 27; % For example, you want data #27 to be a thick line

gp = repelem({'normal'},1,size(X,1));

gp{Nselect} = 'thick'; % Set #27 to be thick

p = parallelplot(X);

p.GroupData = gp; % Set the groupdata

p.LineWidth = [0.5 3]; % Set the line width

p.LegendVisible = 'off'; % Disable the legend if you don't want it to appear

Thank you very much. This problem has been solved. May I ask another question? Can parallelplot modify the length of tick marks? I want to shorten the tick marks.

Checked the documentation and it seems that there is no property related to the tick mark that can be adjusted. May be some other people in the Community knows any workaround about that.
