在chartplotter中获取水平轴的开始和结束的当前值（动态数据显示） [英] get current values of start and end for horizontal axis in chartplotter (dynamic data display)

问题描述

我正在使用d3 chartplotter。在我的应用程序中，我希望程序自动检测显示的水平轴的当前开始和结束值。例如，让我们说用户放大绘制的数据。我知道轴值会自动调整并显示在绘图仪上。我想要的是（在点击按钮时），程序应该提取当时显示的X轴的起点和终点值。我需要这两个值来做其他事情。我正在使用C＃wpf来编程btw。我尝试在论坛中搜索它，但到目前为止没有运气。这就是我所拥有的，包括我最终希望程序做的一些伪代码。但不确定如何进一步实现我的目标。

 CursorCoordinateGraph coordinategraph = 新 CursorCoordinateGraph（）; plotter.Children.Add（coordinategraph）; 
 
 on some_buttonclick（）
 {检索显示的第一个和最后一个x坐标值}} 

非常感谢正确方向的任何指针。



谢谢！

解决方案

我弄清楚了。碰巧太简单了:)

  var  v = plotter。可见; 
  int  X_left = Convert.ToInt32（v.Left）; 
  int  X_right = Convert.ToInt32（v.Right）; 

I am working with d3 chartplotter. In my application, I want the program to automatically detect the current start and end values of my horizontal axis on display. For example, let us say the user zooms in the data plotted. I know the axis value will be automatically adjusted and displayed on the plotter. What I want is (upon a button click maybe), the program should extract what is the start and end value of the X-axis on display at that moment. I need these two values to do some other thing. I am using C# wpf for programming btw. I tried searching for it in forums, but no luck so far. Here's what I have including some pseudocode for what i eventually want the program to do. But not sure how to get any further to achieve my objective.

CursorCoordinateGraph coordinategraph = new CursorCoordinateGraph(); plotter.Children.Add(coordinategraph);

Upon some_buttonclick()
{ Retrieve the first and last x-coordinate value on display...}

Any pointer in the right direction is much appreciated.

Thank you!

解决方案

I figured it out. happened to be too simple :)

var v = plotter.Visible;
int X_left = Convert.ToInt32(v.Left);
int X_right = Convert.ToInt32(v.Right);
