simulink Array plot channel bug?

when I array plot three vector use 3 port , start a run simulation but the channel1 channel2 channel3 sometimes not the same order as the port from up to down?

Please attach the model and plot picture.

[ElectronicABC]

you can see the data input is the same .but color not the same

[madhan ravi]

color doesn"t matter, you didn"t show the legend from the first plot

[ElectronicABC]

the legend from the first plot is the same as bottom

[madhan ravi]

show the picture and attach your model

[ElectronicABC]

[madhan ravi]

why don"t you attach your model?

[ElectronicABC]

run and stop the model multiple times ,you can see the channel changed.

I have attached my test model

It's a bug on 2021A,run the other computer with 2023 all work

Thank you for the model and explanation. I can reproduce the issue with your model in R2021a. Also, as you mentioned, it is not reproducible in recent releases of MATLAB.

It is highly possible that this has been a bug but fixed after R2021a. MathWorks does fix bugs and publishes "updates" for each release. However, as far as I know, R2021a is done with updates with R2021a Update 8.

In this case, I don't think there can be workarounds for R2021a other than updating MATLAB to recent releases.

There can be patches that development team can provide. If you insist to use R2021a, you can reach out to technical support and ask for it. However, I cannot guarantee for patch files because some issues cannot be fixed only with patches.
