Every QCustomPlot has one top level layout of type QCPLayoutGrid. It is accessible via QCustomPlot::plotLayout and contains (directly or indirectly via other sub-layouts) all layout elements in the QCustomPlot. By default, this top level grid layout contains a single cell which holds the main axis rect. Examples

Sep 16, 2022 · 在绘制时控制图层非常简单：使用QCustomPlot::addLayer方法创建一个指定层的图层，如在“main”上层，然后用QCustomPlot::setCurrentLayer设置设置为你刚刚创建的图层，接下来的事情，只需要和往常一样创建图层上的对象即可，因为你设置了当前图层，所以对象都将会放置在该图层。 如果你觉得比较麻烦，可以创建出了图层之后直接使用QCPLayer::setLayer将所有对象放在指定图层。 你甚至可以移动整个图层的内容，方法是QCustomPlot::moveLayer。 在 …

Apr 29, 2017 · I've been looking into the tutorial for qcustomplot but all revolves around drawing a UI with a Qwidget being promoted to QCustomPlot, which is great but Im guessing would require manual drawing if I want more than one Qcustomplot / subplots with fixed / view-able size.

QCustomPlot supports dragging axis ranges with the mouse (QCPAxisRect::setRangeDrag), zooming axis ranges with the mouse wheel (QCPAxisRect::setRangeZoom) and a complete selection mechanism with configurable granularity down to data points and data ranges.

Apr 9, 2017 · You can call clearGraphs () on your QCustomPlot and then add whatever graphs you want to display by calling addGraph () and then call replot () on your QCustomPlot. So it would be something like this: // Do whatever you need to do to edit your graph.

Dec 20, 2023 · QCustomPlot is a Qt C++ widget for plotting. This plotting library focuses on making good looking, publication quality 2D plots, graphs and charts, as well as offering high performance for realtime visualization.

Oct 11, 2023 · 最近在做一个仿真波形的模块，用到了QCustomplot。其中有个功能是模仿matlab的subplot。我的思路是创建多个坐标轴QCPAxisRect，然后往坐标轴添加Graph。最后用QCPItemTracer跟Graph绑定。布局方面就用plotLayout()->addElement()往下添加行。

Under a few circumstances, QCustomPlot causes a replot by itself. Those are resize events of the QCustomPlot widget and user interactions (object selection and range dragging/zooming). Before the replot happens, the signal beforeReplot is emitted. After the replot, afterReplot is emitted. It is safe to mutually connect the replot slot with any ...
