Display large data in Tee Chart

[Gauge]

Hi,


We have been using TeeCart for years. We use Tee Chart 7.06 for Delphi 7. It is a key component of our product.

We need to display a million records or more in Tee chart, and encounter performance issue. It takes a long time in loading that huge data from the file into the graph. To load the data into the graph, our program takes two steps.
1. Read the data from the file to a memory table;
2. Have the chart component check data source.

We wonder if Step 2 could also slow down the program. If so, does TeeChart have any built-in mechnism to limit the number of data points shown on the screen or do we have to develop our custom solution?

Your reply is much appreciated.


Regards,
