在amMap-Amcharts 4中使用javascript更新图像

有一个带有图像的地图，单击这些图像将生成所选项目的列表。单击地图中的选定图像时，取消选择图像并从选定项目列表中删除这些项目

我正在尝试从列表中取消选择所选项目并更新地图中的图像

imageSeries.dataItems.getIndex(index).dataContext.imageURL = "data:image/png;base64,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";

我试着用imageSeries来实现这一点，它改变了href和imageURL，但改变并没有反映在地图上

imageSeries.dataItems.getIndex(index).dataContext.imageURL = "data:image/png;base64,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";
