It seems that the update
method works only with new data. For new types you will need to create a new chart every time.
$(function() {
$("#chartType0").change(function() { createChart($(this).val()) })
function createChart(type) {
new Chart($("#chart0"), {
type: type,
data: {
labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
datasets: [{
label: 'Dataset',
backgroundColor: 'rgba(255, 99, 132, 0.5)',
borderColor: 'rgb(255, 99, 132)',
data: [5, 10, 5, 7, 20, 30, 45]
}]
}
})
}
createChart('line')
})
