水平线上的阈值线 [英] threshhold line in the horizontal line

问题描述

这可能很简单，但我无法弄清楚。我在zed图中有一个线性图。现在我想为一个阈值Y值添加一条直线水平线，例如红色，这样它就会在图表中显示实际数据。我已经知道每个计数器的阈值。

This may be simple, but I'm unable to figure it out. I have a linear graph in zed graph. Now I want to add a straight horizontal line for a threshold Y value in, say, Red so that it shows in the graph along with the actual data. I already know the threshold value for each of my counters.

double threshHoldY = 2;
LineObj threshHoldLine = new LineObj(
    Color.Red,
    graphPane.XAxis.Scale.Min,
    threshHoldY,
    graphPane.XAxis.Scale.Max,
    threshHoldY);
graphPane.GraphObjList.Add(threshHoldLine);

这是我正在尝试的代码，但只绘制了x轴的起点，我想要它用于整个x-axixs。

this is the code i am trying but only draws the line in the beginning of the x- axis, where as i want it for the entire x-axixs.
