代码：
function drawPointsToMap(id, name, x, y, leixing, value, date) { //开始画，画成能够在页面上显示数字的形式。 var point = new esri.geometry.Point(x, y); var textSymbol = new esri.symbol.TextSymbol(value,font1,color1); var sms = new esri.symbol.PictureMarkerSymbol("Content/Default_Index/themes/icons/blue_foot.png", 45, 20); sms.setOffset(1, 5); var infoTemplate = new esri.InfoTemplate(); infoTemplate.setTitle("<div>水质监测点</div>"); infoTemplate.setContent("id：" + id + "<br/>名称：" + name + "<br/>数据：" + value + "<br/>时间：" + date + "<br/>类型：" + leixing); var simpleMarkerSymbol = new esri.symbol.SimpleMarkerSymbol(); var graphic = new esri.Graphic(point, textSymbol); var graphic1 = new esri.Graphic(point, sms); graphicslayer.add(graphic1); graphicslayer.add(graphic.setInfoTemplate(infoTemplate)); }分析：
代码中的id、name、value、date、leixing是需要在infoWindow（infoTemplate）中显示的内容。
x、y是点的坐标
textSymbol是要显示在地图上的内容value
font1和color1 是被写在map主函数中的全局变量。
定义全局变量：
var font1;//这个是字体
var color1;//这个是颜色
require中：
"esri/Color",
"esri/symbols/Font",
function 的小括号中：
Color,
Font,
function 的大括号的开头：
font1 = new Font("13px", Font.STYLE_NORMAL, Font.VARIANT_NORMAL, Font.WEIGHT_BOLDER);
color1 = new Color([255, 255, 0]);
效果图：
利用add_axes属性和subplot属性
代码如下
#解决中文乱码问题 from pylab import * mpl.rcParams['font.sans-serif'] = ['SimHei'] #新建一个figure对象 fig = plt.figure() #新建子图，一行两列，第一个 plt.subplot(1, 2, 1) #画出散点图,x,y代表横纵坐标顺序 t.scatter(x,y, s = 0.1, c = 'r', ) #表明横纵坐标 plt.xlabel('axis_x',fontsize=8) plt.ylabel('axis_y',fontsize=8) #新增子区域，假设整个图为(0,0)到y(1,1)，刚刚subplot在（0，0）到（0.5，1）绘图，此时在（0.5，0）到（0.5，1）区域内标注 #不再利用subplot,因为会画上坐标轴 ax = fig.add_axes([0.5, 0, 0.5, 1]) #在（0.5，0）到（0.5，1）区域写入标注，前两个参数是相对位置 ax.text(0.1,0.95, U'图形名称：相位空间图', transform=ax.transAxes,fontdict = {'size': 8, 'color': 'black'}) ax.text(0.1,0.9, U'观察时间：', transform=ax.transAxes,fontdict = {'size': 8, 'color': 'black'}) ax.set_axis_off() plt.show()
