I would recommend to use plot recipes with Plots.jl (or soon with Makie) instead:
Typical applications of ModiaMath have several plot windows. For example: The first simulation generates three plot windows. The second simulation reuses these windows (clearing their previous content and adding the new results to these windows). This cannot be defined with Plots. Makie does not support multiple windows either but plans to support it in the future. To summarize, if multiple window support is needed, Plots and Makie are (today) no option.
