About

TAChart is the principal component of a TeeChart-like charting framework for Lazarus offered under an LGPL licence. TeeChart is the charting component installed with recent Delphi versions.

It contains functions developed by Philippe Martinole for his TeleAuto project which were revised extensively by Luis Rodrigues when porting the Epanet application from Delphi to Lazarus. Alexander Klenin rewrote and expanded much of the code, and is its current maintainer.

If you have questions, bug reports or feature requests, please post them to the Lazarus mailing list or TAChart board of the Lazarus forum.

Documentation

Many features of TAChart are demonstrated in examples installed at (Lazarus Install Dir)/components/tachart/demo/. See TAChart Demos for a short description and screenshots.

Some TAChart classes and properties have been provided with FPDoc documentation (accessed via [F1] in the IDE).

An overview of most of TAChart's concepts and features can be found in the TAChart documentation.

For beginners, the following tutorials may be helpful:

The rendering may be improved with another library :

Features

  • More than 15 different series, including pie, bar, area, line and point series
  • Function series with domain support
  • No limit to the number of series, points or axes on a graph
  • Flexible chart sources, including design-time editing, and random, dynamic and database-aware sources.
  • Graph legend, title and footer
  • Axis labels and marks can be set manually or auto-generated
  • Axis inversion, independent scale and offset, logarithmic scale
  • Interactive tools, including zoom, panning and crosshairs
  • Automatic or manual graph limits
  • Smart marks drawing
  • Easily extensible with new custom series
  • Output to SVG, OpenGL, printer, WMF, AggPas, BGRABitmap, fpvectorial
  • Can be used in non-GUI applications, such as web services
  • Being actively developed, see roadmap

Screenshot
