Question

我想在ms图表中使用条件构建图形不同的颜色，当我使用此代码时，没有任何反应。这是我的代码。

 if (metroComboBox3.Text == "Temperature")
        {

            chart1.Series[0].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Line;
        //    chart1.Series["Series1"].Points[0].Color = Color.Green;


            chart1.Series[0].Color = Color.Green;
        }

        if (metroComboBox3.Text == "Relative Humidity")
        {
            chart1.Series[1].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Line;
            //    chart1.Series["Series1"].Points[0].Color = Color.Green;
            chart1.Series[1].Color = Color.Red;
        }

Answer 1

chart1.Series[0].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Line;
        chart1.Series[1].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Line;
        chart1.Series[2].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Line;
        if (metroComboBox1.Text == "Text 1")
        {



            for (int i = 0; i < metroGrid1.Rows.Count - 1; i++)
            {
                foreach (DataGridViewRow row in metroGrid1.Rows)
                {
                    int x = 0;
                    Int32.TryParse(metroGrid1.Rows[i].Cells[4].Value.ToString(), out x);

                    DateTime dt;


                    DateTime.TryParse(metroGrid1.Rows[i].Cells[5].Value.ToString(), out dt);

                    chart1.Series[0].Points.AddXY(metroGrid1.Rows[i].Cells[5].Value.ToString(), metroGrid1.Rows[i].Cells[4].Value.ToString());
                    //Console.WriteLine(chart1.Series[0].Points.AddXY(metroGrid1.Rows[i].Cells[5].Value.ToString(), metroGrid1.Rows[i].Cells[4].Value.ToString()));
                }
            }
        }
        if (metroComboBox1.Text == "Text 2")
        {........
