if you are trying to cleat your canvas, but you have lines, you need to begin path again.   So first try this

context.clearRect(0, 0, context.canvas.width, context.canvas.height);
context.beginPath();

== if that doesnt work, try

 

context.clearRect(0, 0, canvas.width, canvas.height);
context.beginPath();

==  and if you had ROTATED OR SCALED YOUR CANVAS, you need to 

ctx.save();
ctx.beginPath();
// Use the identity matrix while clearing the canvas
ctx.setTransform(1, 0, 0, 1, 0, 0);
ctx.clearRect(0, 0, myCanvas.width, myCanvas.height);

// Restore the transform
ctx.restore();//myCanvas.width=myCanvas.width

 

===  and lastly, if that doenst work, you can hack it by... 

context.width=context.width
