Hi,guys

We have a presentation problem in our project,I want to describe it using Analysis mechanism.Following is my draft:
9.2 Analysis Mechanisms
Presentation:
For all need to display chart,we need identify:
Demension: How many dimensions should be displayed?
Style:How many kinds of chart used?
Refresh frequency: Are the chart more or less refresh?
Precision: How to define the precision of the coordinates' value?
Volume: Number of charts to display in one page.
Synchronicity: Does the chart changing dynamicly according to the database updated?
Reliability: Shall the objects survive a crash of the process; the processor; or the whole system?
Usability: Developed by ourselves or use other open source project? Use applet or servlet?
9.3 Design Mechanisms
Presentatiion:
We utilize third party open source project as the way to resolve the above analysis mechanism.
Demensiion:2 dimensions,use series as the different value of color.
Style: 3 kinds of chart.columnarity,pie,coordinate.
Refresh frequency: utilize token as the way to avoid frequency refresh.
Precision: decimal places:2
Synchronicity: not synchronicity when data changed,get the newest result by refresh .

but I don't know if it is right,Please help me checking it and tell me how to correct it.thanx a lot.
