如何修复带有文字的Google地图标记图标

Question

您好我正在使用谷歌地图标记图标和文字使用谷歌图表API https://chart.googleapis.com/chart?chst=d_bubble_text_small&chld=bbT|27.b|f4b605|0f3276

在我的地图中，如果文字太长，图标不固定如何修复它

这是我的js代码：

<script type="text/javascript">

                    var CITY_MAP_ZOOMING_FACT = 9;
                    var infowindow;

                    /**
