问：想创建这样的3D图形衍生函数图像，但是却出现System.ArgumentOutOfRangeException问题，有什么错误/span>

void __3d(vector<int>y) {lightningChartUltimate1 = gcnew LightningChartUltimate(); lightningChartUltimate1->BeginUpdate();cli::array<SeriesPoint3D>^ points = gcnew cli::array<SeriesPoint3D>(y.size());for (size_t i = 0; i < y.size()-1; i++) {points[i].X = i * 0.2;points[i].Y = y[i + 1] - y[i];points[i].Z = i * 0.2;}lightningChartUltimate1->View3D->PointLineSeries3D[0]->Points = points; //System.ArgumentOutOfRangeException:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: indexlightningChartUltimate1->EndUpdate();                             }

回复：需要创建PointLineSeries3D对象并将其添加到集合View3D-> PointLineSeries3D，因为最初的集合为空。

3D图表Winforms C ++示例一样发布了它

void __3dchart(vector<int> y){chart3d->BeginUpdate();chart3d->Parent = tabControl1->TabPages[1];chart3d->Name = "3D line plot";chart3d->ActiveView = ActiveView::View3D;//create Series objauto series = gcnew PointLineSeries3D(chart3d->View3D, Axis3DBinding::Primary, Axis3DBinding::Primary, Axis3DBinding::Primary);series->PointStyle->Shape3D = PointShape3D::Sphere;series->PointStyle->Size3D->SetValues(1, 1, 1);series->Material->DiffuseColor = Color::Navy;series->Material->SpecularColor = Color::Red;series->Material->SpecularPower = 20;series->LineVisible = true;series->LineStyle->AntiAliasing = LineAntialias::Normal;series->LineStyle->Color = Color::FromArgb(100, Color::Red);series->LineStyle->Width = 0.2f;series->LineStyle->LineOptimization = LineOptimization::NormalWithShading;series->PointsVisible = false;chart3d->View3D->PointLineSeries3D->Add(series);//add seriesauto series1 = chart3d->View3D->PointLineSeries3D[0];        series1->Clear();//clear for new  pointscli::array<SeriesPoint3D> ^ points = gcnew cli::array<SeriesPoint3D>(y.size());vector<double> yz;//for max min XYZ correctionfor (size_t i = 0; i < y.size() - 1;i++) {points[i].X = points[i].Z = i*0.2;double v = points[i].Y =  y[i+1] - y[i];yz.push_back(v);}//XYZ correctionchart3d->View3D->YAxisPrimary3D->Maximum = *std::max_element(std::begin(yz), std::end(yz));chart3d->View3D->YAxisPrimary3D->Minimum = *std::min_element(std::begin(yz), std::end(yz));chart3d->View3D->XAxisPrimary3D->Maximum = yz.size()*0.2;//maxXchart3d->View3D->ZAxisPrimary3D->Maximum = yz.size()*0.2;//maxZseries1->Points = points;chart3d->EndUpdate();}
