Sometimes we require to reset a canvas when we want to replace the graph with another set of data. that time simply resigning may cause issue, we can reomove and recreate elements for that purpose
function reset_element(element_id, element_type){
var child = document.getElementById(div_id);
var parent = child.parentElement;
var new_child = document.createElement(element_type);
parent.removeChild(child);
new_child.setAttribute('id', div_id);
parent.appendChild(new_child);
}
// <span id="my_canvas_id"></span>
