How do I move the caption in the canvas Pie chart?

Are you referring to the labelsCenter option?

If so you can move it like this (add this code after you create the chart):

node = document.getElementsByClassName('rgraph_accessible_text_labels_center')[0];
node.style.left = parseInt(node.style.left) + 50 + 'px';
node.style.top = parseInt(node.style.left) + 50 + 'px';

Which is a bit long-winded - so as of the next version there will be two new options that make it a lot easier:

...
labelsCenter: 'Results!',
labelsCenterOffsetx: 50,
labelsCenterOffsety: 50,
...
