Qt如何将以下程序写成一个for循环

Question

初始化一些图表的程序都很相似，想简化代码，将这些图表的初始化写进一个for循环里面，但不知道如何下手。

chart1->removeAllSeries();

chart2->removeAllSeries();
chart3->removeAllSeries();
chart4->removeAllSeries();

if(chart1->axisX()!=NULL)
    {
    chart1->removeAxis(chart1->axisX());
    chart1->removeAxis(chart1->axisY());
    }

if(chart2->axisX()!=NULL)
    {
    chart2->removeAxis(chart2->axisX());
    chart2->removeAxis(chart2->axisY());
    }
if(chart3->axisX()!=NULL)
    {
    chart3->removeAxis(chart3->axisX());
    chart3->removeAxis(chart3->axisY());
    }
if(chart4->axisX()!=NULL)
    {
    chart4->removeAxis(chart4->axisX());
    chart4->removeAxis(chart4->axisY());
    }

使用过QList，但没成功

简化代码量

Answer 1

注意，这里只能传入指针的引用或者指针的指针，才能修改实参chart1、chart2、chart3、chart4的内容

void fun(QChart *&chart)
{
    chart->removeAllSeries();
    if(chart->axisX()!=NULL)
    {
        chart->removeAxis(chart->axisX());
        chart->removeAxis(chart->axisY());
    }
}
fun(chart1);
fun(chart2);
fun(chart3);
fun(chart4);
