Hi, guys. I have write a program, that connected to sensors and log data to mysql database, it also drawing real time line chart. I would like writes copies that program but it runs remotely over internet, i mean to transfer data of the chart(moving) over internet. so i can monitor that program(watching the chart over internet, real time). Is that possible? Where can I start? Which controls in delphi would help me do that? Thanx for help.

True real-time across the internet is impossible due to latency and timing problems, near real-time is possible.
TChartFX can draw charts.
The Database tab in the component repository contains numerous database components, including SQL components.
I would start with a local machine if I were you. Then you can always add the internet connectivity in a later stage.
