Hello dear community, I would like to know if it is possible to make a real time trend with Lazarus as shown in this video:
https://www.youtube.com/watch?v=37Zj955LFT0In this case there would be two types of trends:
The first one generates the trend from a numerical value inserted through a TEdit1.
The second Trend reads the numerical data stored in a database and is generated from a query parameterized by dates and times.
Where I am recommended to start reading to achieve this.
I appreciate your time.
Pdt. Please excuse my little knowledge of English.
