Update on November 17, 2020

⚠️ I am reducing effort on issues and PRs while I work on this daily.

• See changelog.md for a summary of major changes.
• See roadmap.md for a big-picture discussion of plans and goals
• I merged ScottPlot 4.1.0 #605 which accomplishes most of the goals described on this page
• The master branch is now ScottPlot 4.1-beta. Old source code has its own 4.0-stable branch.

Refactor / Large Features

Remaining Tasks

• Make GetAxisLimits() return AxisLimits object
• Create a control to test a timer-based render method
• Create new plottables specifically for growing data (mark public data fields readonly and provide setters to replace data arrays)
• Improve data validation for plottables (create separate pre-render and deep validation methods in an interface)

Extra release of 4.0

• Add RenderLock() and RenderUnlock() fields to help with multi-threaded plot manipulation
• Add NuGet message noting transition to 4.1 and to check preleases
• Review all the items on Triaged Tasks and Features (May 2020) #412 since many have now been completed or made obsolete
