Qt Charts Bar Plot Resize Crash - c++

Question

Situation:
I wrote a bar plot using QtCharts, QChartView, QChart, QBarSeries, QBarSet, QValueAxis and QCategoryAxis and it works fine.
Problem:
When i resize the window or use QRubberbandon the plot, it crashes.
What i tried:
Every other plot i wrote is not affected by that problem, including the ones using QStackedBarSeries. The Problem also occured in another program i wrote in the same situation.
Code - Head:
int D_Plot::Plot_Stat_Multi_MeanMedian(
QChartView *pChartView,
vector<vector<double> > *vv_SetSta,
bool pl_mean,
bool pl_sd,
bool pl_median,
bool pl_adm,
QString name_title,
QString name_categories,
QString name_y)
Code - Body:
//Chart
QChart *chart = new QChart();
chart->setTitle(name_title);
//Sets
QBarSet set_mean("Mean");
QBarSet set_sdev("Standard Deviation");
QBarSet set_medi("Median");
QBarSet set_aadm("Average Absolute Deviation from Median");
//Categories
QStringList categories;
//Series
QBarSeries *series = new QBarSeries();
for(unsigned int set = 0; set < vv_SetSta->size(); set++)
{
if(pl_mean) set_mean.append((*vv_SetSta)[set][c_STAT_MEAN_ARITMETIC]);
if(pl_sd) set_sdev.append((*vv_SetSta)[set][c_STAT_STAN_DEV_SAMPLE]);
if(pl_median) set_medi.append((*vv_SetSta)[set][c_STAT_MEDIAN]);
if(pl_adm) set_aadm.append((*vv_SetSta)[set][c_STAT_ABS_DEV_MED]);
categories.append(QString::number(set));
}
if(pl_mean) series->append(&set_mean);
if(pl_sd) series->append(&set_sdev);
if(pl_median) series->append(&set_medi);
if(pl_adm) series->append(&set_aadm);
chart->addSeries(series);
//Axis
QBarCategoryAxis *X_axis = new QBarCategoryAxis();
X_axis->append(categories);
X_axis->setTitleText(name_categories);
chart->setAxisX(X_axis, series);
QValueAxis *Y_axis = new QValueAxis();
Y_axis->setTitleText(name_y);
chart->setAxisY(Y_axis, series);
//Showing
pChartView->setChart(chart);
return ER_Okay;

Answer 1

You are creating your QBarSet objects locally (i.e. not via the new operator) and passing a pointer to these sets to the QBarSet::append method which AFAIK takes ownership if the objects pointed to i.e feels obliged to de-allocate them when going out of scope. This is bound to fail with locally allocated objects.
