我正在使用来自应用程序的C#窗口。我正在使用TeeChart for .net v3来绘制图表。我能够为每个创建多个不同颜色的Y轴,如下图所示。 现在我能够显示具有不同颜色的轴,但我也希望将相同的轴颜色分配给其轴的刻度。请帮助我使用我需要的财产。
还有一个问题是如果我有多个轴,那么它会占用图表上的大量空间来为每个轴创建单独的轴。我想要水平分配轴的尺度,而不是我现在得到的尺度。请任何人帮助我,我需要使用哪些属性。 我想表示比例和轴,如下图所示。
提前致谢。

我制作了一个简单的代码,我已经为我绘制的每个自定义轴设置了相同的比例,并自动将所有轴放在正确的位置。我认为你可以使用类似的代码来尝试实现你想要的:
public Form1()
{
InitializeComponent();
InitializeChart();
}
private DataSet GetData()
{
DataSet TeeDataSet = new DataSet();
DateTime dt = DateTime.Today;
DataTable TeeDataTable = new DataTable("DataTable1");
DataColumn xval = new DataColumn("DateTime", typeof(DateTime));
DataColumn yval = new DataColumn("SystemName", typeof(double));
TeeDataTable.Columns.Add(xval);
TeeDataTable.Columns.Add(yval);
Random rnd = new Random();
for (int i = 0; i < 10; i++)
{
DataRow newRow = TeeDataTable.NewRow();
newRow[xval] = dt;
newRow[yval] = rnd.Next(100);
TeeDataTable.Rows.Add(newRow);
dt = dt.AddMonths(1);
}
TeeDataSet.Tables.Add(TeeDataTable);
return TeeDataSet;
}
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
tChart1.Header.Visible = false;
tChart1.Legend.Alignment = LegendAlignments.Bottom;

{
new Steema.TeeChart.Styles.Line(tChart1.Chart);
tChart1[i].Title = "SystemName";
tChart1[i].DataSource = GetData();//Add values using DataSource
tChart1[i].XValues.DataMember = "DateTime";
tChart1[i].XValues.DateTime = true;

private void PlaceAxes(int nSeries, int NextXLeft, int NextXRight, int MargLeft, int MargRight)
{
const int extraPos = 12;
const int extraMargin = 60;
//Variable
int MaxLabelsWidth;
int lenghtTicks;
int extraSpaceBetweenTitleAndLabels;
foreach (Steema.TeeChart.Styles.Line s in tChart1.Series)
{
if (s.Active)
{
s.CustomVertAxis.Visible = true;
s.CustomVertAxis.SetMinMax(tChart1[0].YValues.Minimum, tChart1[0].YValues.Maximum);
MaxLabelsWidth = s.CustomVertAxis.MaxLabelsWidth();
lenghtTicks = s.CustomVertAxis.Ticks.Length;
extraSpaceBetweenTitleAndLabels = (s.CustomVertAxis.Title.Width);//- tChart1.Axes.Custom[nSeries].MaxLabelsWidth());
if (s.CustomVertAxis.Title.Visible)
{
s.CustomVertAxis.RelativePosition = NextXLeft;
NextXLeft = NextXLeft - (MaxLabelsWidth + lenghtTicks + extraSpaceBetweenTitleAndLabels + extraPos);
MargLeft = MargLeft + extraMargin;
}
else
{
s.CustomVertAxis.RelativePosition = NextXLeft;
NextXLeft = NextXLeft - (MaxLabelsWidth + lenghtTicks + extraPos);
MargLeft = MargLeft + extraMargin;
}
tChart1.Panel.MarginLeft = MargLeft;
tChart1.Panel.MarginRight = MargRight;
}
else
{
s.CustomVertAxis.Visible = false;
}
}
}
您能否告诉我们以前的代码是否适用于您?如果您有任何问题,请告诉我。
我希望能有所帮助。
谢谢,
