## What it is
JKQtPlotter is an extensive C++ plotting and charting framework for Qt5 and Qt6, featuring a feature-rich plotter widget, a speed-optimized variant, and an integrated LaTeX equation renderer. It is fully self-contained with no dependencies beyond the Qt framework itself.

## Use cases
- plot scientific data in a Qt application
- render charts and graphs in C++ desktop apps
- display barcharts and statistical plots with Qt widgets
- render LaTeX equations in Qt GUIs
- export plots to PDF or PNG from a Qt app
- visualize image data in a Qt widget

## When to choose
- you are building a Qt5/Qt6 desktop application that needs high-quality 2D plotting
- you want a plotting library with no dependencies beyond Qt
- you need LaTeX-rendered axis labels and annotations
- you need print/export support and rich user interactions out of the box

## When to avoid
- your project does not use the Qt framework
- you need web-based or JavaScript charting
- you need 3D plotting capabilities

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts, graphics
- domain: data-visualization, desktop-applications
- platform: cpp, cross-platform
- tags: qt5, qt6, plotting-library, latex-renderer, scientific-plotting, charting, widgets, scientific-visualization, desktop
