ChartDirector是著名的商业图表, 包含有以下功能:
可以免费下载使用, 但是免费版底部会有一个黄色的版权条.
这里演示下饼状图表的aardio中调用简单例子:(这里是在文件目录生成一个图表图片)
import win.ui;
/*DSG{{*/
mainForm = win.form(text="aardio工程6";right=690;bottom=428)
mainForm.add()
/*}}*/
var dll = ..raw.loadDll("\res\chartdir60.dll",,"cdecl");
CPieChart_create = dll.api("CPieChart_create","pointer(int,int,int,int,int)" );
PieChart2BaseChart = dll.api("PieChart2BaseChart","pointer(pointer)" );
CPieChart_setPieSize = dll.api("CPieChart_setPieSize","void(pointer,int,int,int)" )
CPieChart_set3D = dll.api("CPieChart_set3D","void(pointer,int,double,bool)" )
CPieChart_setExplode = dll.api("CPieChart_setExplode","void(pointer,int,int)" )
CBaseChart_addTitle = dll.api("CBaseChart_addTitle","pointer(pointer,string,string,double,int,int,int)" )
CBaseChart_makeChart = dll.api("CBaseChart_makeChart","bool(pointer,string)" )
CPieChart_setData = dll.api("CPieChart_setData","void(pointer,pointer,int,pointer,int)" )
var paichart =CPieChart_create(280, 240,0xffffff,0,0);
var chart = PieChart2BaseChart(paichart);
CPieChart_setPieSize(paichart,140, 130, 80);
CBaseChart_addTitle(chart,"aardio-ChartDirector-demo","bold",12,0,0xffffff,0);
CPieChart_set3D(paichart,-1,-1,false);
var buff1 = raw.buffer({double data[7]={45, 18, 15, 12, 8, 30, 25}});
var buff2 = raw.buffer({string data[7]={"aardio", "c#", ".net", "reby", "labview", "html","php"}});
CPieChart_setData(paichart,buff1,7,buff2,7);
CPieChart_setExplode(paichart,0,-1);
CBaseChart_makeChart(chart,"demo.png");
mainForm.show();
return win.loopMessage();其他功能类似, 不过看c++的示例需要把类库自己翻译过来.
注意看上面的代码中, 有CPieChart和CBaseChart开头, 它们分别对应操作不同的对象,所以后面的参数里第一个参数就是不同的那个对象, 针对这个示例, Pie就是饼图对象和Base基类对象. 这点要注意, 要不然得不到你想要的效果.

感谢，测试一下 ChartDirector 的 COM 控件：
//RUNAS// import win.ui; var cd = com.TryCreateObject("ChartDirector.API") if(!cd){ import inet.installer; if(inet.installer("ChartDirector","https://www.advsofteng.net/chartdir_com.exe")){ var file = io.open("C:\Program Files (x86)\ChartDirector\lib\chartdir60.dll","r+b") if(file){ // C:\Program Files (x86)目录写文件需要管理权限 file.seek("set",0x218054) file.write('\0\0'); file.seek("set",0x218084) file.write('\0\0'); file.close(); } cd = com.TryCreateObject("ChartDirector.API") } else{ return; } } /*DSG{{*/ var winform = win.form(text="ChartDirector 控件测试";right=759;bottom=469;bgcolor=16777215) winform.add( picturebox={cls="plus";left=31;top=16;right=726;bottom=436;bgcolor=16777215;repeat="scale";z=1} ) /*}}*/ // Create a XYChart object of size 250 x 250 pixels var c = cd.XYChart(250, 250) // Set the plotarea at (30, 20) and of size 200 x 200 pixels c.setPlotArea(30, 20, 200, 200) // Add a bar chart layer using the given data c.addBarLayer({85, 156, 179.5, 211, 123}) // Set the labels on the x axis. c.xAxis().setLabels({"Mon", "Tue", "Wed", "Thu", "Fri"}) //c.makeChart2(cd.PNG); //c.makeChart("demo.png"); //ChartDirector 自带的显示控件效果很差，改用 plus 控件 var pic = com.GetIPicture( c.makePicture() ); //pic.Save("/test.jpg"); winform.picturebox.background = pic; winform.show(); win.loopMessage();
