How to change OxyPlot Y-Axis string format?
提问by John August
Can anyone tell me how to change the Y axis string format??
谁能告诉我如何更改 Y 轴字符串格式？
I have Y-Axis percentages that I want to add the percent sign to.
我有要添加百分号的 Y 轴百分比。
I am using OxyPlot to produce the chart in wpf.
我正在使用 OxyPlot 在 wpf 中生成图表。
Here is my attempt, but it is NOT working:
这是我的尝试，但它不起作用：
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.
这会产生空引用错误。
Thanks!
谢谢！

This is an example I've used previously to format the x-axis on an oxy-plot:
这是我之前用来在 oxy-plot 上格式化 x 轴的示例：
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);

this._PlotModel.Axes.Add( new LinearAxis
{
Position = AxisPosition.Left,
Minimum = 0.025,
Maximum = 0.205,
StringFormat = "0.00%",
MajorStep = 0.005
} );
- add percents as ratio: 20.5% --> 0.205, 0.5% --> 0.005, etc.
- 添加百分比作为比率：20.5% --> 0.205、0.5% --> 0.005 等。
