MsChart是微软制作的功能强大的图表工具，用它可以很方便的建立各种图表。制作各种3维2维的直方图，折线图。结合前一段时间我对Mschart组件的认识，谈谈Mschart组件的使用方法。
1、 Chart Activex控件： 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. http://support.microsoft.com/support/kb/articles/Q159/9/23.ASP
2、 Mschart组件的一些常用属性介绍 a、charttype：图形的类型 charttype=0＞三维直方图 charttype=1＞二维直方图
charttype=2＞三维折线图 charttype=3＞二维折线图 charttype=4＞三维面积图 charttype=5＞二维面积图
charttype=14＞饼图 b、showlegend：是否显示解说 c、titletext：标题 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: http://www.4guysfromrolla.com/webtech/MSChartExample.shtm
