Hello. I am using Julia for the first time.
I want to use the function ‘timeseries\_steps\_mean’ which is explained in the under website.
> **[Parallel Ensemble Simulations · DifferentialEquations.jl](https://docs.sciml.ai/DiffEqDocs/stable/features/ensemble/)**
>
> Documentation for DifferentialEquations.jl.
It says that
> The `mean` and `meanvar` versions return a `DiffEqArray` which can be directly plotted.
Okay. So I tried to plot. But this happens…
```julia
plot(timeseries_steps_mean(sol_SSA))
```
```julia
type DiffEqArray has no field indepsym

So I found if the value of timeseries\_steps\_mean is something wrong, but nothing is wrong…

Okay, I want to plot this data. But when I try, it always says ‘type DiffEqArray has no field indepsym’.
How can I solve this problem??

Which version of DiffEq are you on? Your question in the other thread suggested you are working with an old version, so make sure that your version matches the version of whatever documentation you are looking at.

I am using DifferentialEquations v7.7.0.
And the documentation I am looking (if it need to solve the problem) is : [Using MomentClosure · MomentClosure.jl](https://augustinas1.github.io/MomentClosure.jl/dev/tutorials/using_momentclosure/#)

But we had already established in the other thread that `vars` is not a supported keyword in DiffEq v7 any longer, so it is likely that MomentClosure relies on the plotting API of an older version of DiffEq - the last MomentClosure release is 9 month old and doesn’t have compat bounds for DiffEq so the docs probably haven’t been updated to the latest DiffEq version.
