dotnetcharting 如果实现动态浏览图表 像股票那样
先上demo代码
/// Summary description for g01.
public class g01
{
public g01()
{
}
public void CreateChart(ref Chart chart1)
{
// Set the title.
chart1.Title="My Chart";
// Set 3D
chart1.Use3D = true;
// Set the chart Type
chart1.Type = ChartType.Financial;
// Label the chart areas
chart1.PriceArea.Label.Text = "Stock Price for X Company";
chart1.VolumeArea.Label.Text = "Volume";
// Set the financial chart type
chart1.DefaultSeries.Type = SeriesTypeFinancial.CandleStick;
// Set the legend template
chart1.LegendBox.Template = "IconName";
// Set the directory where the images will be stored.
chart1.TempDirectory="temp";
// Set the format
chart1.VolumeArea.XAxis.FormatString = "d";
// Set the time padding for the x axis.
chart1.VolumeArea.XAxis.TimePadding = new TimeSpan(5,0,0,0);
// Set he chart size.
chart1.Width = 600;
chart1.Height = 350;
// Add the random data.
chart1.SeriesCollection.Add(g01.getData());
//
// TODO: Add any constructor code after InitializeComponent call
//
}
static private SeriesCollection getData()
{
SeriesCollection SC = new SeriesCollection();
Random myR = new Random(1);
for(int i = 0; i < 1; i++)
{
Series s = new Series();
s.Name = "X Company";
double startPrice = 50;
DateTime startDT = new DateTime(2000,1,1);
for(int b = 0; b < 75; b++)
{
Element e = new Element();
e.XDateTime = startDT;
startDT = startDT.AddDays(1);
if(myR.Next(10) > 5)
startPrice += myR.Next(5);
else
startPrice -= myR.Next(3);
e.Close = startPrice;
e.Volume = myR.Next(100);
if(myR.Next(10) > 5)
e.Open = startPrice + myR.Next(6);
else
e.Open = startPrice - myR.Next(6);
if(e.Open > e.Close)
{
e.High = e.Open + myR.Next(6);
e.Low = e.Close - myR.Next(6);
}
else
{
e.High = e.Close + myR.Next(6);
e.Low = e.Open - myR.Next(6);
}
s.Elements.Add(e);
}
SC.Add(s);
}
return(SC);
}
}
这个demo图标就跟股票图很像了 可以如何实现动态浏览呢 如按上下键后 能够动态的放大缩小 左右键能够左右平移
有人做过类似的图没
现在就是一死图

這個也有這樣功能，可能比較好用，網站
补充：.NET技术 , C#
