.. to handle axis rulers automaticly
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.
