- By default, no anti-aliasing is done on line plots for performance reasons. My apps use 4X MSAA, so I didn't see any reason to waste cycles on software AA. However, you can enable AA with the `ImPlotFlags_AntiAliased` flag.
- If you plan to render several thousands lines or points, then you should consider enabling 32-bit indices by uncommenting `#define ImDrawIdx unsigned int` in your `imconfig.h` file, OR handling the `ImGuiBackendFlags_RendererHasVtxOffset` flag in your renderer (the official OpenGL3 renderer supports this). If you fail to do this, then you may at some point hit the maximum number of indices that can be rendered.
## FAQ
**Q: Why?**
A: ImGui is an incredibly powerful tool for rapid prototyping and development, but provides only limited mechanisms for data visualation. Two dimensional plots are ubiquitous and useful to almost any application. Being able to visualize your data in real-time will give you insight and better understanding of your application.
**Q: Is ImPlot suitable for real-time plotting?**
A: Yes, within reason. You can plot tens to hundreds of thousands of points without issue, but don't expect plotting over a million to be a buttery smooth experience. We do our best to keep it fast and avoid memory allocations.
**Q: Can plot styles be modified?**
A: Yes. Plot colors, palletes, and various styling variables can be pushed/popped or modified permantly on startup.
**Q: Does ImPlot support logarithmic scaling?**
A: Yep!
**Q: Does ImPlot support X plot types?**
A: Maybe. Check the gallery and demo to see if your desired plot type is shown. If not, consider submitting an issue or better yet, a PR!
**Q: Does ImPlot support 3D plots?**
A: No, and likely never will since ImGui only deals in 2D rendering.
**Q: Does ImPlot provide analytic tools?**
A: Not exactly, but it does give you the ability to query plot sub-ranges, with which you can process your data however you like.
**Q: Can plots be exported/saved to image?**
A: Not currently. Use your OS's screen capturing mechanisms if you need to capture a plot. ImPlot is not suitable for rendering publication quality plots; it is only intended to be used as a visualization tool. Post-process your data with MATLAB and matplotlib for these purposes.
