title: Changes in Slider has to reflect in Core plot Graph
body: <p>I have slider in one view and Bar chart using core plot in its sub view(view 2).
  At first the bar chart shows graph for default data in viewDidLoad method(it has initial values for slider).</p>
  
  <p>When the slider changes the graph should reflect the bar chart accordingly.But i could not reflect the changes in slider in the graph.Is there any way to get my thing done.I can change the label in other view(view 2) when ever slider changes by some IBAction for this slider change.</p>
