如何避免 ZedGraph 重新标记我的 YAxis(除以 1000)?
我正在创建一个 C# Visual Studio 表单应用程序,它使用 zedgraph 来绘制程序收集的数据的图表,但在绘制数据时遇到以下问题:
我的 y 轴值通常在 100,000+ 范围内,因此当 zed graph 绘制时它用 0、10、15、20、25 等内容标记 y 轴标签的值,然后在 y 轴标签上附加“(10^3)”标题并将相应地绘制值。我想要做的是让它用 0、10,000、15,000、20,000 等值或 0、10k、15k、20k 等值标记 y 轴,而不让它调整 y 轴标题。
我尝试设置 YAxis.Scale.MajorStep = double.Parse("10000"); ,但唯一的效果是在 y 轴上添加大量刻度线,但没有其他效果。这是我的绘制数据图表的代码:
private void createGraph()
{
GraphPane myPane = zdc_graph.GraphPane;
myPane.CurveList.Clear();
myPane.GraphObjList.Clear();
myPane.Title.Text = this.monitoredHost.hostName + "\nWorkState[" +
this.monitoredHost.currentWorkState + "]";
myPane.XAxis.Title.Text = "";
myPane.YAxis.Title.Text = "OPS Per Second";
myPane.YAxis.Scale.FontSpec.FontColor = Color.Blue;
myPane.YAxis.Title.FontSpec.FontColor = Color.Blue;
myPane.YAxis.Scale.MaxAuto = true;
myPane.Y2Axis.Title.Text = "Reading";
myPane.Y2Axis.IsVisible = true;
myPane.Y2Axis.Scale.FontSpec.FontColor = Color.Red;
myPane.Y2Axis.Title.FontSpec.FontColor = Color.Red;
myPane.XAxis.Type = AxisType.Date;
myPane.XAxis.Scale.Format = "T";
myPane.XAxis.Scale.MajorUnit = DateUnit.Second;
myPane.YAxis.Scale.Min = 0;
myPane.YAxis.Scale.MajorStep = double.Parse("10000");
myPane.Y2Axis.Scale.Min = 0;
LineItem kpiCurve = myPane.AddCurve("OPS Per Second",
this.monitoredHost.graphKpiList,
Color.Blue,SymbolType.Circle);
LineItem pwrCurve = myPane.AddCurve("Reading",
this.monitoredHost.graphPwrList, Color.Red,
SymbolType.Circle);
kpiCurve.Line.Width = 2.0F;
kpiCurve.Symbol.Size = 4.0F;
kpiCurve.Symbol.Fill = new Fill(Color.White);
pwrCurve.Line.Width = 2.0F;
pwrCurve.Symbol.Size = 4.0F;
pwrCurve.Symbol.Fill = new Fill(Color.White);
pwrCurve.IsY2Axis = true;
myPane.Chart.Fill = new Fill(Color.White, Color.FromArgb(255, 255, 210), -45F);
zdc_graph.AxisChange();
zdc_graph.Refresh();
}
我希望这是有道理的。感谢您的帮助。
I am creating a C# visual studio forms application that uses zedgraph to chart the data that the program collects but I am running into the following issue when plotting the data:
My y-axis values are usually in the 100,000+ range so when zed graph plots the value it labels the y-axis labels with stuff like 0, 10, 15, 20, 25 and then on the y-axis label it will append "(10^3)" to the title and will plot the values accordingly. What I want to do is have it label the y-axis either with values like 0, 10,000, 15,000, 20,000 etc or 0, 10k, 15k, 20k and so on and not have it adjust the y-axis title.
I tried setting YAxis.Scale.MajorStep = double.Parse("10000");
but the only effect that has is to add a ton of more tick lines on the y-axis but no other effect. Here is my code that graphs the data:
private void createGraph()
{
GraphPane myPane = zdc_graph.GraphPane;
myPane.CurveList.Clear();
myPane.GraphObjList.Clear();
myPane.Title.Text = this.monitoredHost.hostName + "\nWorkState[" +
this.monitoredHost.currentWorkState + "]";
myPane.XAxis.Title.Text = "";
myPane.YAxis.Title.Text = "OPS Per Second";
myPane.YAxis.Scale.FontSpec.FontColor = Color.Blue;
myPane.YAxis.Title.FontSpec.FontColor = Color.Blue;
myPane.YAxis.Scale.MaxAuto = true;
myPane.Y2Axis.Title.Text = "Reading";
myPane.Y2Axis.IsVisible = true;
myPane.Y2Axis.Scale.FontSpec.FontColor = Color.Red;
myPane.Y2Axis.Title.FontSpec.FontColor = Color.Red;
myPane.XAxis.Type = AxisType.Date;
myPane.XAxis.Scale.Format = "T";
myPane.XAxis.Scale.MajorUnit = DateUnit.Second;
myPane.YAxis.Scale.Min = 0;
myPane.YAxis.Scale.MajorStep = double.Parse("10000");
myPane.Y2Axis.Scale.Min = 0;
LineItem kpiCurve = myPane.AddCurve("OPS Per Second",
this.monitoredHost.graphKpiList,
Color.Blue,SymbolType.Circle);
LineItem pwrCurve = myPane.AddCurve("Reading",
this.monitoredHost.graphPwrList, Color.Red,
SymbolType.Circle);
kpiCurve.Line.Width = 2.0F;
kpiCurve.Symbol.Size = 4.0F;
kpiCurve.Symbol.Fill = new Fill(Color.White);
pwrCurve.Line.Width = 2.0F;
pwrCurve.Symbol.Size = 4.0F;
pwrCurve.Symbol.Fill = new Fill(Color.White);
pwrCurve.IsY2Axis = true;
myPane.Chart.Fill = new Fill(Color.White, Color.FromArgb(255, 255, 210), -45F);
zdc_graph.AxisChange();
zdc_graph.Refresh();
}
I hope this makes sense. Thanks for the help.

ZedGraph 正在尝试检测幅度并简化图表。您可以通过以下方式关闭此功能:
这将产生 y 轴标签,如
100000
。如果您想使用分隔符逗号设置标签格式,例如
100,000
:最后,如果您希望显示
100k
,则需要订阅ScaleFormatEvent< /code> 并返回您自己的格式,如下所示:
ZedGraph is attempting to detect magnitude and simplify the graph. You can turn this off with the following:
This will result in y-axis labels like
100000
.If you want to format the label with a separator comma like
100,000
:Finally, if you prefer to show
100k
, you'll need to subscribe to theScaleFormatEvent
and return your own format, like this:我有类似的问题。因此,应用您的方法,它可以在应用程序上工作,但我也想打印 PDF 文件中的图形(使用 MigraDoc),但它确实有效。
I am having similar problem. So applying your method it works on the application but i also want to print out the graph in a PDF file (using MigraDoc) but it does work.
