MS Chart control with WPF

Question

Ive got a MS Chart control and it works just fine except that I can't figure out how to "format" the Y-Axis. I am adding a lot of double numbers into a Serie but when the double numb are actually whole numbers (20.000000.....) the Y-Axis on my chart shows 20.

example: this serie :
12.32
11.00
10.13
would actually show up like this:
12.32
11
10.13

I have tried formatting the data as I insert it into the serie like this:

serie.Points.AddXY(date.ToString(),double[i].ToString("##.##"));

but that doesn't seem to work.

I've tried to search for a place to format it in Chart.Series[0].* and Chart.ChartAreas[0].* but I didn't find it there.

Answer 1

使用“ 0.00”作为格式字符串，“ ##。##”将在末尾去除零

serie.Points.AddXY(date.ToString(),double[i].ToString("0.00"));

Answer 2

I know this might come too late, but here's my advice.

You can find out more about numeric format for strings, here and here .

I think you need fixed point ("F") format specifier used like this:

chart1.ChartAreas["Default"].AxisY.LabelStyle.Format = "F2";

Also you should add numbers to your data points' Y values, not strings. Hope that helps.
