What is the problem with showing the data? The graph is data too.
If you do not want to show *absolute* data, you must at least show *relative* data, otherwise the graph can not be drawn...

i wanted to get data in graph from SQL Database directly. i don't want to display source table values into excel. is it possible?

If you want Excel to draw the graph, you need data for it in Excel. E.g. do it manually - you always have a data set to produce the graph.
Use other means/tools or produce a PDF or an image of the graph to present to the user.

To do this you can take advantage of an Excel library for C# / VB.NET, like this:
- First you need to create an Excel file in C# / VB.NET.
- Second you need to export a DataTable to an Excel file in C# / VB.NET.
- Third you need to create an Excel chart in C# / VB.NET.
I hope this helps.
