suppose we want to change the y value of x-label 'march' from 40 to 50. first change the first dataset's value of 'march' to be 50.
now calling update
function animates the position of 'march' from 40 to 50.
mynewchart.datasets[0].points[2].value = 50; //change the value
mynewchart.update(); //update the chart
