asp畫圖實現k線圖

可以考慮使用MSCHART，但是缺點是顯示不太好看，不很專業，同時，如果用戶端沒有裝的話就比較麻煩，因為顯示不出來，所以一般的網站都採用產生圖片的方式。下面給出MSCHART的一些東西，可以自己考慮著使用，我沒有使用過其他的控制項，所以不能給你滿意的回覆。另外附給你一個網址，www.tjinfo.com,裡面有個調查題，使用了MSCHART，但是沒有用折線，這個你可以自己定義的，CSDN的調查也使用了MSCHART。

看看我的這篇總結，你會受益匪淺！
關於Mschart的說明文檔

MsChart是微軟製作的功能強大的圖表工具，用它可以很方便的建立各種圖表。製作各種3維2維的長條圖，折線圖。結合前一段時間我對Mschart組件的認識，談談Mschart組件的使用方法。
1、 Chart Activex控制項：
In the HTML page, insert an <OBJECT> tag for the License Manager object before any other <OBJECT> tags. The License Manager is an ActiveX control that is installed with Internet Explorer.
NOTE: This CLASSID, "5220cb21-c88d-11cf-b347-00aa00a28331", is for the License Manager and not for your ActiveX controls. You must use the same CLASSID every time you refer to the LPK file. In addition, you should keep the Name property of the <PARAM> tag as "LPKPath", and set the Value property for the <PARAM> tag of the License Manager object to the LPK file name and path. This path may be a relative path but must not refer to a UNC share or a URL on another domain.
Because you can only have one LPK file for each HTML page, make sure that you include all of the licensed ActiveX Controls for the page when you generate your LPK file. For example:
<object CLASSID="clsid:5220cb21-c88d-11cf-b347-00aa00a28331"
id="Microsoft_Licensed_Class_Manager_1_0">
<param NAME="LPKPath" VALUE="mschart.lpk">
</object>
Insert the <OBJECT> tag for your licensed control afterward. For example, an HTML page that displays the Microsoft Masked Edit control looks like this.
Here I downloaded the file mschart.cab from Microsoft's website. It has been digitally signed.
<OBJECT classid="clsid:3A2B370C-BA0A-11D1-B137-0000F8753F5D"
id=mschart1 style="HEIGHT: 326px; WIDTH: 651px" CODEBASE="mschart.cab"></OBJECT>
You can look this acticle if you need help.

2、 Mschart組件的一些常用屬性介紹
a、charttype：圖形的類型
charttype=0>三維長條圖
charttype=1>二維長條圖
charttype=2>三維折線圖
charttype=3>二維折線圖
charttype=4>三維面積圖
charttype=5>二維面積圖
charttype=14>餅圖
b、showlegend：是否顯示解說
c、titletext：標題
d、Columncount: The number of data columns
e、Rowcount:The number of data rows
f、Footnotetext:The footnote text.
g、Plot: Returns a reference to a Plot object that describes the area upon which a chart is displayed.
h、row: A row number in the current column. Rows are numbered from top to bottom beginning with 1. column: The current data column.
i、Rowlabel: The text for a row label. The label you specify sets the label for the data points identified by the Row property. This label appears along the category axis for most chart types and is used as the label for each individual pie in a pie chart. Label text may not be displayed if it is too long to fit on a chart.columnlabel: . Label text associated with a column in the data grid.
j、Data: The data point value. If the current data point already contains a value, it is replaced by the new value. The chart is redrawn to reflect the new value for the current data point.
k、ChartData: A two-dimensional array that holds the data used to draw the chart. If the first series of a multi-dimensional array contains strings, those strings will become the labels of the chart.ChartData is the default property for the MSChart control.
It is so many properities about Mschart Activex.I only introduce so much.Now,I will provide your two example to you!I wish it can help you understand it.
Example 1:It come from:

<script LANGUAGE="Vbscript">

MSChart1.Plot.Axis(1).Labels(i).Format = "$0,###"
MSChart1.Plot.Axis(1).Labels(i).VtFont.Name = "Tahoma"
MSChart1.Plot.Axis(1).Labels(i).VtFont.Size = 10
Next
MSChart1.RowCount = 5
MSChart1.ColumnCount =2
MSChart1.ShowLegend = True
for y = 1 to 2
for x = 1 to 5
MSChart1.Row = x
MsChart1.Column= y
MSChart1.RowLabel = "Row " & x
call MSChart1.DataGrid.SetData(x, 1, x*5,nullFlag)
call MSChart1.DataGrid.SetData(x, 2, x*10,nullFlag)
next
Mschart1.ColumnLable=y
next

Example 2:We almost can see it everywhere.
