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 so far. But not sure how to get any further to achieve my objective.
CursorCoordinateGraph coordinategraph = new CursorCoordinateGraph();
plotter.Children.Add(coordinategraph);
Upon buttonclick()
{ Retrieve the first and last x-coordinate value on display...}
Any pointer in the right direction is much appreciated.
Thank you!
