Comprehensive list of TeeGrid features: https://github.com/Steema/TeeGrid-VCL-FMX-Samples/wiki/3.-Getting-Started TeeGrid is free for non-commercial use.

https://github.com/Steema/TeeBI/blob/master/demos/experiments/bigdata/OneBillion/readme.md This demo shows TeeBI capabilities with big quantities of data, rows and cells. It first creates a default dummy database of One Billion cells (thousand millions). Data is saved to a disk file in your TEMP folder: "big_data.bi" (4.5GB) in aprox 4 seconds. Once data has been created it can be loaded again from disk in aprox 2.5 seconds. The "Query and Visualize" form uses this big data to do some visualizations. (Queries traversing so many millions of rows are not immediate, of course !) But you can run them in a normal laptop. // Sum the amount of Sales year by year, all rows: BIQuery1.Measures.Add(BigData['Sales']['Total'], TAggregate.Sum); BIQuery1.Dimensions.Add(BigData['Sales']['Date']).DatePart := TDateTimePart.Year; BIComposer1.Data := BIQuery1.Calculate;

Visualize complex multi-dimensional data using #TeeBI Composer control. Minimal code, automatic output. https://github.com/Steema/TeeBI/tree/master/demos/delphi/Visualization/Composer

Demo source code: https://github.com/Steema/TeeBI/tree/master/demos/delphi/Geographic/USA_Counties Note: This demo needs the "Pro" version of TeeChart.

The "if" inside the "for" is also taking time. Try with 2 for loops, one for direct and another for indirect. Also the indirect routine could be marked as "inline" to eliminate the call. This is fine for short small routines.

I guess most Delphi code is private, never available to AI agents to train, something like dark-matter or dark-energy. A pity 😓

New TeeBI demo, one line of code calls the Google Gemini api and imports the results into normal TeeBI structures. These data then can be simple visualized or queried. The idea is to add more AI agents (ChatGPT etc) transparently in the near future. https://github.com/Steema/TeeBI/tree/master/demos/3rd_party/AI uses BI.AI, BI.DataItem; procedure TForm_AI_Demo.Button1Click(Sender: TObject); var Data1 : TDataItem; begin // One line of code, call Gemini and get a data structure: Data1:=TBIAI.From('your key', 'Give me the list of the highest 10 mountains by elevation in csv format, just the list', TBIAI.GoogleGemini); // Visualize it: BIGrid1.Data:=Data1; // in the grid BIChart1.Data:=Data1; // in the chart end;

🤣🤣 And a youtube video ! Clarity first !

Showcasing the TeeBI Query editor, drag and drop fields to create pivot tables of multiple dimensions, custom functions and features not available with SQL (like histograms, by code expressions, or using your functions and events to control the query "where/having" filters etc). Free and opensource: https://github.com/Steema/TeeBI

Series1.LinePen.Width := 3; should work fine

Small example to access Github's contributions of a given user and display them using TeeChart. https://github.com/Steema/TeeChart-VCL-GitHub-Contributions This demo is made with VCL but almost identical code works in Firemonkey.

Just an alternative, TeeGrid can be used for gantt applications too. A customer from Canada recently sent us their app, the grid allows multiple top layers (columns and subcolumns, for year, month, date, etc) and rows (tasks) can contain children rows (unlimited levels, subtasks) with a "+" left column to expand / collapse. Tasks are then custom painted using the grid Canvas (Rectangle, Triangle, etc methods) using the columns coordinates. https://www.steema.com/product/gridvcl https://steema.com/wp/blog/2025/06/18/powering-precision-in-manufacturing-intelligence-dynafact-dms-with-teechart/

TeeBI is now available at GetIt for RAD Studio 12: https://getitnow.embarcadero.com/teebi/ The listed "category" needs to be fixed, its not a "Trial" version but a fully functional, free opensource component library. More advanced demos and the BIWeb server sources are located at GitHub. The same installer detects and compiles TeeBI for other RAD versions you might have installed in your system.

Hmm, I'm not sure if the free TeeChart Lite version has this, but sure the Pro version allows "sub axes" (what you say titles of 3 layers, are the TChart.Axes.Top (first layer with dates) and two sub axes added to it, one for hours, one for seconds. Cosmetics I think allow to match the screenshot with some customization, to some extent. Navigation (scroll, clicks, drag etc) are provided. More complex is (if I see the screenshot well) the ability to expand left side texts, like a tree/explorer of levels. It can also be done but its not as easy as a property or adding "children" rows to any row.

TeeChart includes a basic Gantt series style with some features (resizing and moving tasks, cursors etc) but maybe not as complex as the screenshot you posted. Axes left and top are fully capable though. https://www.steema.com/docs/teechart/vclfmx/tutorials/UserGuide/html/manu8nsk.htm
