title: Alternatives to the HitTest()
body: <p>Currently my software uses the <code>HitTest()</code> method of a chart object in MSCharts but as I scale this up to more and more data points on my chart combined with other factors this can have a massive performance hit.</p>
  
  <p>I was wondering if there any alternatives that you know of to provide the same functionality ( get the X Coordinate on the chart for the cursor position ) but without the performance hit as hit testing seems to be a very brute force way of obtaining my answer.</p>
  
  <p>My chart is created from the class <code>System.Windows.Forms.DataVisualization.Charting.Chart</code></p>
  
  <p>Edit for clarity: I need to find the position of a line on my chart to use it for other calculations.</p>
