bkbb：
When I compare your work in the tutorial below:
https://careydevelopment.us/2017/07/01/add-charts-spring-boot-app-highchart/
You are trying to draw a pie chart which expects integer values when passed a list ${listGraph}.
series: [{
name: 'Regions',
colorByPoint:true,
data: [{
name: 'Northeast',
y: [[${listGraph}]]
}
]
