Scroll Graph Horizontally in Custom View

I have made a graph by extending View and made graph dynamically what i want is to scroll that graph because my mobile screen is smallit takes all xaxis values so i want it to scroll horizontall

What i have done is

        HorizontalScrollView hsv=new HorizontalScrollView(this);
            ll=new LinearLayout(this); //taking Linear Layout
            ll.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT,1.0f));
            ll.setOrientation(android.widget.LinearLayout.VERTICAL);
            ll.addView(graphView);//My Graph 
            hsv.addView(ll);
            setContentView(hsv);

I want to this Dynamically because my entire code is dynamic So i need help , it is not showing the graph when i implement this

Solution

Hi you can do one thing, instead of trying scroll graph

Horizontally try to swipe drawing lines and points ,its easy

all we have to swipe canvas view
