About

TAChart is a charting LGPL component for Lazarus (TeeChart like). It contains the functions that Philippe Martinole developed for the TeleAuto project and lots of changes introduced by Luis Rodrigues while porting the Epanet application from Delphi to Lazarus.

Its main caracteristics are :

* Pie Series
* Bar Series
* Area Series
* Line Series (can work as Point Series)
* Unlimited number of  graphs
* Unlimited number of points
* Graph legend
* Graph title
* Graph footer
* Axis labels
* Interactive zoom
* Reticule or vertical reticule with point measure
* Mirror on X axis
* Auto or manual graph limits
* Smart marks drawing
* Vertical and horizontal line graph type
* Easily extensible to new graph types


The download contains the component, an installation package and a demo application, that illustrates the features of the component along with some instrumentation for evaluating the chart on a given system.

This component was designed for cross-platform applications.
