Question

当该组被折叠/隐藏时，chart.getImage()方法会在组（数据＆gt;大纲＆gt;组）中导致以下错误。

我使用chart.getImage()来获取base64编码的图像，因此可以通过编程方式将图表插入到Word / PowerPoint文档中。

此功能是Excel-to-Word文档自动化加载项的一部分。即使在组中折叠，用户也希望能够获取图像。

Excel for Windows和Excel Online（可能还有Mac）出现错误

这可能与Office.js Excel Online > chart.getImage() errors

有关

这是一个可以修复的错误（或者它是否会被支持）？有没有已知的解决方法？

重现ScriptLab中的错误：

function run() {
    Excel.run(function (ctx) {
        var chart = ctx.workbook
            .worksheets.getItem("Sheet1")
            .charts.getItem("Chart1");

        var image = chart.getImage();

        return ctx.sync().then(function () {
            console.log("done");
        });

    }).catch(function (error) {
        console.log("Error: " + error);
        if (error instanceof OfficeExtension.Error) {
            console.log("Debug info: " + JSON.stringify(error.debugInfo));
        }
    });
}

图片展示如何折叠组。要创建组：数据＆gt;概要＆gt;组

Office.js Excel＆gt; chart.getImage（）在折叠组中出错
