针对你提出的问题“qcustomplot can't use opengl because qcustomplot_use_opengl was not defined”,以下是详细的解答步骤: 检查项目配置文件: 你需要检查你的项目配置文件(如.pro文件),确保已经定义了QCUSTOMPLOT_USE_OPENGL宏。这个宏告诉QCustomPlot在编译时启用OpenGL支持。 在你
void QCustomPlot::setOpenGl(bool enabled, int multisampling) { mOpenGlMultisamples = qMax(0, multisampling); #ifdef QCUSTOMPLOT_USE_OPENGL mOpenGl = enabled; if (mOpenGl) { if (setupOpenGl()) { // backup antialiasing override and labelcaching setting so we can restore upon disabling OpenGL ...
Plot性能提升 QCustomPlot采用了大量的技术比如自适应采样和文本对象缓存为了减少replot的时间。然而一些特...
If enabled is set to false, the antialiasing/label caching settings are restored to what they were before OpenGL was enabled, if they weren't altered in the meantime. Note OpenGL support is only enabled if QCustomPlot is compiled with the macro QCUSTOMPLOT_USE_OPENGL defined. This define must...
- OpenGL hardware acceleration is now available across all Qt versions (including Qt4) in a unified, simple interface, with QCustomPlot::setOpenGl (experimental) - QCPStatisticalBox can now display a series of statistical boxes instead of only a single one ...
Failing to do so can not be detected by the container efficiently and will cause both rendering and potential data loss. Implementing one-dimensional plottables that make use a \ref QCPDataContainer<T> is usually done by subclassing from \ref QCPAbstractPlottable1D"...
