示例读取HYSPLIT模式输出的气团轨迹数据文件，生成轨迹图层，并显示轨迹各节点的气压图。
脚本程序：
f = addfile_hytraj(‘D:/MyProgram/Distribution/java/MeteoInfo/MeteoInfo/sample/HYSPLIT/tdump‘) tlayer = f.trajlayer() stlayer = f.trajsplayer() axesm(position=[0.1,0.4,0.8,0.6]) mlayer = shaperead(‘D:/Temp/map/country1.shp‘) geoshow(mlayer, edgecolor=(0,0,255), facecolor=(230,230,230)) geoshow(tlayer) ss = makesymbolspec(‘point‘, {‘marker‘:‘S‘}) geoshow(stlayer, symbolspec=ss) xlim(-92, -55) ylim(34, 54) title(‘MeteoInfoLab script demo - Trajectory‘) axes(position=[0.1,0.1,0.8,0.3], yreverse=True, xaxistype=‘time‘) data = f.trajvardata(12) plot(data, legend=tlayer.legend()) xlabel(‘Time‘) ylabel(‘hPa‘)
