是否可以在标签末尾绘制轴标签？详情见图片：

如果可能，怎么做？
vtkNew<vtkContextView> contextView;
vtkNew<vtkTable> table;
vtkNew<vtkChartXY> chart;
vtkNew<vtkDoubleArray> timeAxis;
vtkNew<vtkDoubleArray> realDataAxis;
vtkNew<vtkDoubleArray> measuredDataAxis;
// ...
contextView->SetInteractor(vtkWidget->GetInteractor());
vtkWidget->SetRenderWindow(contextView->GetRenderWindow());
timeAxis->SetName("t");
realDataAxis->SetName("x(t)");
measuredDataAxis->SetName("x*(t)");
table->AddColumn(timeAxis.Get());
table->AddColumn(realDataAxis.Get());
table->AddColumn(measuredDataAxis.Get());
chart->SetShowLegend(true);
auto legend = chart->GetLegend();
legend->GetLabelProperties()->SetFontSize(14);
legend->GetLabelProperties()->SetFontFamilyToTimes();
auto xAxis = chart->GetAxis(vtkAxis::BOTTOM);
xAxis->SetTitle(QApplication::translate("DataSetChartWidget", "t").toStdString());
auto xTitleProps = xAxis->GetTitleProperties();
xTitleProps->SetFontSize(14);
xTitleProps->SetFontFamilyToTimes();
auto xLabelProps = xAxis->GetLabelProperties();
xLabelProps->SetFontSize(14);
xLabelProps->SetFontFamilyToTimes();
auto yAxis = chart->GetAxis(vtkAxis::LEFT);
yAxis->SetTitle(QApplication::translate("DataSetChartWidget", "x(t), x*(t)").toStdString());
auto yTitleProps = yAxis->GetTitleProperties();
yTitleProps->SetFontSize(14);
yTitleProps->SetFontFamilyToTimes();
auto yLabelProps = yAxis->GetLabelProperties();
yLabelProps->SetFontSize(14);
yLabelProps->SetFontFamilyToTimes();
contextView->GetScene()->AddItem(chart.Get());
和绘图代码：
auto realPlot = chart->AddPlot(vtkChart::LINE);
realPlot->SetInputData(table.Get(), 0, 1);
auto measuredPlot = chart->AddPlot(vtkChart::POINTS);
measuredPlot->SetInputData(table.Get(), 0, 2);
