如何改变OxyPlot Y轴字符串格式？ [英] How to change OxyPlot Y-Axis string format?

问题描述

谁能告诉我如何改变Y轴字符串格式??

我有Y轴的百分数，我想添加百分号。

我使用OxyPlot生产WPF中的图表

下面是我的尝试，但它不工作：

  Func键<双，串> formatFunc =（X）=>的String.Format（{} 000.00％，X）; 
 
 formatFunc =新Func键与LT;双，串>（{0}）; 
 //添加情节窗口
 line.YAxis.LabelFormatter = formatFunc; 
  

这会产生空引用错误。

！谢谢

解决方案

这是我以前用来格式化上的氧情节x轴的例子：

  VAR XAXIS =新的DateTimeAxis 
 {
位置= AxisPosition.Bottom，
的StringFormat =DD / MM / YYYY，
标题=日结束，
 IntervalLength = 75，
 MinorIntervalType = DateTimeIntervalType.Days，
 IntervalType = DateTimeIntervalType.Days，
 MajorGridlineStyle = LineStyle.Solid，
 MinorGridlineStyle = LineStyle.None，
}; 
 
地块=新PlotModel（）; 
 Plot.Axes.Add（X轴）; 
  

Can anyone tell me how to change the Y axis string format??

I have Y-Axis percentages that I want to add the percent sign to.

I am using OxyPlot to produce the chart in wpf.

Here is my attempt, but it is NOT working:

Func<double, string> formatFunc = (x) => string.Format("{000.00}%", x);

        formatFunc = new Func<double,string>("{0}");
        // Add the plot to the window
        line.YAxis.LabelFormatter = formatFunc;

This produces null reference error.

Thanks!

解决方案

This is an example I've used previously to format the x-axis on an oxy-plot:

var xAxis = new DateTimeAxis
{
    Position = AxisPosition.Bottom,
    StringFormat = "dd/MM/yyyy",
    Title = "End of Day",
    IntervalLength = 75,
    MinorIntervalType = DateTimeIntervalType.Days,
    IntervalType = DateTimeIntervalType.Days,
    MajorGridlineStyle = LineStyle.Solid,
    MinorGridlineStyle = LineStyle.None,
};

Plot = new PlotModel();
Plot.Axes.Add(xAxis);
