Plotting waveform data from database

Hi! I'm acquiring single-point waveform data from my DAQ board, plotting it on a waveform chart, and then after say every 1 second, storing the same in a database(as waveform data without any explicit conversion).
I then tried to retrieve all the data from the database and plot it on waveform chart (after appropriate coversion from the DB variant tye). Being a "chart", the chart now shows only the last few seconds of data.

I want all the Temperatuire vs time values to be visible together. I tried using Waveform graph, but it doesn't show up any graph at all!

Please help! This is real urgent. I'm ataching the VI.

I can't comment on your code specifically because it's not in V6.0 format, but if you can repost it in that form I'll be glad to look at it.

In the mean time, what database are you using? How are you communicating with the database? What is the structure of the table you are storing the data in? In particular, what datatype are you using for the data?

If you are using SQL to insert and query the data, also post those statements.
