How to change the properties of a plot obtained from compare(mdl,data) function.

I use "compare(mdl,data)" function. This function plots the test component degradation data in data superimposed on the most similar data sets from the historical ensemble stored in the fitted similarity model. However, the qualiy of the fiqure is not good enough. For instance, I want to double the linewidth or change the color of the lines. could you please me help me how can I do it?

Many thanks

I don’t have the Predictive Maintenance Toolbox so I have no direct experience with it. However it exists with the online Run feature, so I gave some effort to getting the information necessary to address the problems mentioned. It took a bit of handle spelunking, however was not as difficult as some other plot types in other MATLAB Toolboxes.

I include an example at the end on how to set the red line to have a LineWidth of 5 —

D1 = load('pairwiseTrainTables.mat');
pairwiseTrainTables = D1.pairwiseTrainTables;
D2 = load('pairwiseTestData.mat');
pairwiseTestData = D2.pairwiseTestData;

mdl = pairwiseSimilarityModel;
fit(mdl,pairwiseTrainTables,"Time","Condition")

figure
compare(mdl,pairwiseTestData)                                       % Original

figure
compare(mdl,pairwiseTestData)                                       % Test

Ax = gca;
% GetAx = get(Ax)
Kids = Ax.Children

Hi,

You can add formatting to your plots by adding name-value pair arguments to "compare" function. For instance, to double the linewidth or change the color of the line, to say red, you may write the following line in your code:

compare(mdl,data,'r','LineWidth',10)

Hi,

Many Thanks. I already tried it.

But the formatting such as linewidth or color changing is not working for this function

[Tanmay Das]

Can you please share your reproduction steps(all the code that is required to reproduce the issue at my end) for further investigation?
