我有这些XY值：
Series S1 = new Series() S1.Points.AddXY(9,25); S1.Points.AddXY(10,35); S1.Points.AddXY(11,15); chart1.Series.Add(S1);
但我需要在图中显示X值,如下所示：
X = “9-10”
X = “10-11”
X = “11-12”
我怎样才能做到这一点？
到目前为止,这是我发现的：
这是代码：
private void Form1_Shown(object sender,EventArgs e)
{
chart1.ChartAreas[0].AxisX.Minimum = 7;
chart1.ChartAreas[0].AxisX.Maximum = 15;
Series S1 = new Series();
S1.Points.AddXY(9,25);
S1.Points.AddXY(10,35);
S1.Points.AddXY(11,15);
chart1.Series.Add(S1);
chart1.Series[0].Points[0].AxisLabel = "9-10";
chart1.Series[0].Points[1].AxisLabel = "10-11";
chart1.Series[0].Points[2].AxisLabel = "11-12";
你可以看到我使用数字,并为X轴标签设置文本,但我只能为DataPoints值做这些,我需要它用于整个值范围.
有什么想法吗？
解决方法
以下是sipla的答案：
string[] range = new string[10];
private void Form1_Shown(object sender,EventArgs e)
{
chart1.ChartAreas[0].AxisX.Minimum = 7;
chart1.ChartAreas[0].AxisX.Maximum = 16;
range[0] = "";
range[1] = "7-8";
range[2] = "8-9";
range[3] = "9-10";
range[4] = "10-11";
range[5] = "11-12";
range[6] = "12-1";
range[7] = "1-2";
range[8] = "2-3";
range[9] = "";
Series S1 = new Series();
S1.Points.AddXY(9,15);
chart1.Series.Add(S1);
}
int count;
private void chart1_Customize(object sender,EventArgs e)
{
count = 0;
foreach (CustomLabel lbl in chart1.ChartAreas[0].AxisX.CustomLabels)
{
lbl.Text = range[count];
count++;
}
}
