Know that TeeChart is powerful but not sure how to use it?
Interested in doing something with the data that comes out of your smart meter?
Roger Connell demonstrates features of Standard TeeChart (as available in Delphi) and touches on additional extras in the Pro version, using data from his electricity usage of the last few years.
We will also spend some time talking about future directions for ADUG, so if you have any thoughts/suggestions/quibbles, this is a good time to share them.
Meeting time 6:00 pm for 6:15 start with questions and discussion, followed by the presentation at 6:30, Melbourne time (AEST).
Sorry for this very delayed (and as a result, somewhat vague) post.
Roger Connell showed us some of the Delphi TChart’s functionality.
The Pro Version is fairly expensive and does more, but the one that
comes with Delphi (vcl std, fmx lite) works quite well.
There are also versions available which include source.
Feature Matrix
The project demoed involved importing Power Statistics previously
retrieved from AGL, (get 2 years worth at a time) and displaying them on
a T Chart.
Could interactively zoom in and out and pan around.
Can see when you had holidays. (Power consumption drop)
It seems to work quite well.

Some possibilities
Product Comparisons, analysis
Would like to see Product Comparisons, Analyse and find Pros and Cons
eg. Javascript Transpilers
Put a focus on Delphi, Javascript for some time.
Scripting
Would like stuff in Python, (perhaps scripting generally)
Python seems to be used a lot in data analysis, machine learning scenarios.
Following one of Grahame Grieves presentations, I did a little with
Delphi and the ChakraCore javascript engine at one stage.
Have played with DWScript, (parsing DFM files to JSON, editing and
converting back to DFM)
(DWScript now used in SmartMobileStudio)
Spring4D
Study group on Spring4d,
Focus on project for using spring4d.
Intro to spring4d
Would like some examples.
Putting data into memory and extract.
Overview one time, and then a week later?
Talk about books we have read
Delphi in all its glory
Code better in Delphi
Scripting
More elegant approaches C#, F# etc.
Free Pascal

Brief discussion around DunitX and FPC
(No attributes is a problem),
** turns out FPC does now have attributes, Can they be made usable **

Need people and product
Most important is security probably
