Automatic Axis Scaling Tool in Delphi

.. to handle axis rulers automaticly

 Description    Copyright     Download  

Automatic axis scaling routine to create scientific notations and intelligent offset handling.

The application is used to create a automaticly linear scaled axis pair a for plain coordinate systems and comes with two sample applications. It supports automatic scientific notation scaling to use unit prefixes like k-kilo, m-milli etc.

The sample applications containing a simple console application which demonstrates the how you can determining positions of axis ticks and the axis labeling for a given interval of real world data within a graphical range. It is the basic code to develop your own graphical applications. A more complex graphical application demonstrate the use of canvas wrapper and the use of affine coordinate transformations with the unit UDrawChartGrid. These application contains also a tool, to determin the affine transformation between real world data and screen world data via pass point calculation.
