[Plots] plot performance degradation in vue from angular

[davetsay]

Summary

Plotting data (after receiving the data) takes longer in new Vue plots as it did in AngularJS plots for large data sets. UI becomes locked during plotting.

Expected vs Current Behavior

Vue plots should perform at least as well as legacy AngularJS plots

Impact Check List

• Data loss or misrepresented data?
• Regression? Did this used to work or has it always been broken?
• Is there a workaround available?
• Does this impact a critical component?
• Is this just a visual bug?

Steps to Reproduce

1. ensure time conductor is in fixed time mode
2. select any plot object with decently sized data
3. select a larger timeframe if more data needed
4. observe time to plot
5. expand plot to max size (maximize window size, collapse tree and inspector panes)
6. observe time to plot

• This was observed with identical build environments and data, but different software builds, where the vue plots lagged significantly with the high res plot.

Environment

• Open MCT Version:
• Deployment Type:
• OS:
• Browser:

Additional Information

Good idea to check vue reactivity. if data is somehow being reactified.
