如何在 balkangraph orgchart 中“修复缩放功能”错误？

Question

当我初始化巴尔干组织结构图时。它适合屏幕，但我需要在初始化时缩小。但是当我使用我在代码中提到的图表变量调用缩放函数时，它会抛出错误。

chart.zoom(0.5)

var chart = new OrgChart(document.getElementById("tree"), {
                        template: "rony",
                        nodeMouseClick: OrgChart.action.none,
                        mouseScrool: OrgChart.action.zoom,
                        align: OrgChart.ORIENTATION,
                        enableSearch: false,
                        showXScroll: OrgChart.none,
                        toolbar: {
                            zoom: true,
                            fit: true,
                            expandAll: false
                        },
                        collapse: {
                            level: 2,
                            allChildren: true
                        },
                        nodeBinding: {
                            field_0: "name",
                            field_1: "title",
                            field_2: "department",
                            img_0: "img",
                            field_number_children: "field_number_children"
                        },
                        nodes: nodes
                    });

我希望输出在初始化时缩小图表。

使用scaleInitial 选项：

var chart = new OrgChart(document.getElementById("tree"), {
    scaleInitial: 0.5
});
