aardio - 【库】scottPlot图表控件库
ScottPlot是个非常不错的基于C# 的图表控件库，开源免费，官方的文档和例程也比较丰富，学起来比较容易。
封装C#库，我也是第一次尝试，目前还有某些功能不完善，以后慢慢改进。
顺便用 customPlus库 + scottPlot库 做了一个演示程序，简单演示一句代码添加图形，效果如下：
演示程序代码如下：
import win.ui;
import godking.customPlus
import godking.scottPlot
/*DSG{{*/
var winform = win.form(text="scottPlot图表控件库演示 by 光庆";right=759;bottom=419)
winform.add(
custom={cls="custom";text="自定义控件";left=270;top=10;right=750;bottom=410;bgcolor=16777215;db=1;dl=1;dr=1;dt=1;z=3};
plus2={cls="plus";left=10;top=10;right=250;bottom=410;autohscroll=false;autovscroll=false;bgcolor=16777215;clipBk=false;db=1;dl=1;dt=1;notify=1;z=1};
scrollbar={cls="scrollbar";left=250;top=10;right=270;bottom=410;db=1;dl=1;dt=1;z=2}
)
