Hello everybody,

I am a newbie to programming.
Folloing is my problem,

I am getting serial out put as ascii string codes containing particle size distribution .It contains 50 seperate values denoting frequancy distribution.I have stored those values as 50 different numeric fields. I want to plot scatterxy chart with x axis bearing field name at a equidistance while Y arm should contain field-data value for one recordset only.can anybody guideme ?

N.B. In excel I could get the desired result with smooth line scatter graph option after storing value in one column.

It's always better to store fields like that in different rows.
When you have one row with 50 fields a (large) UNION query could be used to transform the data like:
Expand|Select|Wrap|Line Numbers
  1. select 1 as Sequence, field1 from table1
  2. UNION
  3. select 2 as Sequence, field2 from table1
  4. UNION
  5. select 3 as Sequence, field3 from table1
  6. UNION
  7. ... etc
Getting the idea ?

Hi, there.

First of all I would like to recommend you to read the article on Database Normalization and Table structures. If you'll still feel difficulties of how to implement general database rules in your project, then I'll be happy to give you some help.
