Chart.js在哪里添加paddingRight属性

Question

var ctx = document.getElementById("canvas-chart").getContext("2d"),
                data = {
                    labels: [ "RP.800,000", "RP.400,000", "RP.200,000"],
                    datasets: [{
                            label: "",
                            data: [ "800000", "400000", "200000"],
                            borderColor: "#744c7e",
                            lineTension: 0,
                            pointBorderColor: "#bfc766",

正如您所看到的，最后一个工具提示被切断了。

根据Chart.js doc，我想添加 paddingRight ，我不知道如何。请帮忙。

我尝试添加尺度，但它不起作用。

当我按照文档并使用registerScaleType也失败。
