To remove an item from a QCustomPlot in C++, you can use the removeItem() function. Here's an example:
```cpp
// Assuming you have a QCustomPlot object called "customPlot"
// Get a pointer to the item you want to remove (e.g. a graph or legend item)
QCPAbstractItem* itemToRemove = customPlot->legend->item(0); // Replace with your own item
// Remove the item from the plot
customPlot->removeItem(itemToRemove);
```
This will remove the specified item from the plot. Note that if the item is a graph, you may also need to remove any associated axes and data as well.
