Class Image_Graph_Axis_Values


Class for handling textual and numerical values on the axes

This class provied methods and attributes for customization of an axis. You can use it to set the options like the font, it's size or the color in which values (both numerical and textual, depending on the axis) will be drawn. For a numerical axis this class also offers you functionality to set the format in which numbers will be drawn. You can use this to set the number of decimal digits, prepend or append text etc. For a textual axis (actually: for the x-axis) this class allows you to set the text-labels which will be drawn.

Set numberformat for numerical values on the axis

Use this to set the format in which numbers on the axis will be drawn. E.g. you can use it to set a certain number of decimal values or prepend/append text to the numbers. Numbers will be drawn at all "major ticks" on the axis. Note that the "numberformat" is only used if the type of the axis is numerical (linear or at some later step even logarithmic), not if it's a textual axis (x-axis).
