public class SymmetricLogPanel
extends GraphPanel

This generator produces graph paper similar to log paper. The intervals begin at the axis (horizontal or vertical) and progressively shrink (or grow) as they move away from it. The settings that control this are:

The other two settings are for the axis pen and the line pen.

Each axis can have a linear or logarithmic scale. The '[]Linear' checkbox determines how an axis is scaled. NOTE: the vertical scale applies to the vertical axis and the horizontal scale applies to the horizontal axis. The pens are opposite to their scales: the vertical pens affect the horizontal lines and vise versa! The horizontal and vertical components can also be disabled, if desired.

Method Detail

drawGraph

public void drawGraph(int pTop,
                      int pBot,
                      int pLeft,
                      int pRight,
                      SVGTag pPaper)
Draw the thing.

Overrides:
drawGraph in class GraphPanel
Parameters:
pTop - The top margin of the drawable area.
pBot - The bottom margin of the drawable area.
pLeft - The left margin.
pRight - The right margin.
pPaper - The SVGTag on which the drawing is to occur.

setScaleType

public void setScaleType(boolean pVertLinear,
                         boolean pHorizLinear)
Set the scale type for each axis.

Parameters:
pVertLinear - 'true' to make the vertical scale linear, 'false' for logarithmic.
pHorizLinear - 'true' for a linear horizontal scale, 'false' for logarithmic.

setSpacing

public void setSpacing(double pVertSpace,
                       double pHorizSpace)
Set the initial spacing for each axis. Values less than one are ignored, allowing each value to be set individually.


setMinSpace

public void setMinSpace(double pVertMin,
                        double pHorizMin)
Set the minimum interval size for each axis. Any value less than 0.1 is ignored.


setScale

public void setScale(double pVertScale,
                     double pHorizScale)
Set the interval scale factor. Values less than 0.1 are ignored.


setCycle

public void setCycle(int pVertCycle,
                     int pHorizCycle)
Set the cycle length before the scale factor is applied. Values less than one are ignored.


setAxisPen

public void setAxisPen(int pVertPen,
                       int pHorizPen)
Set the pen used for the vertical and horizontal axis. Negative values are silently ignored.


setLinePen

public void setLinePen(int pVertPen,
                       int pHorizPen)
Set the line pen for the vertical and horizontal axis. Negative values are silently ignored.


reset

public void reset()
Reset to starting values.

Overrides:
reset in class GraphPanel

toPizza

public java.lang.String toPizza(java.lang.String pPrefix)
Description copied from class: GraphPanel

This method extracts the configuration and state information from a generator and produces java.util.Properties-style output. A String prefix can be prepended to each key. If 'pPrefix' is not null or blank it will be attached to the front of the key String, separated by a single dot. If the prefix does not end with a dot one will be supplied automatically.

Use of the prefix allows multiple configurations to be stored in a single file. Also, since each generator has its own unique prefix (separate from the one supplied) multiple generator configs can be stored in a single file.

This is primarily a scripting method. It was developed in order to allow the perfect settings to be saved in a (scripting-) language-agnostic way that was also human-readable. The individual property names are typically Java-fied versions of their GUI labels. If MathTools is run from its JAR and the standard GUI is present the instances exposed to scripts are the ones in the GUI, so setting values in the GUI will affect script output and settings made by the script are reflected in the GUI.

Specified by:
toPizza in class GraphPanel
Parameters:
pPrefix - The prefix to prepend to each key. Ignored if null or blank.

eatPizza

public void eatPizza(java.util.Properties pPizza,
                     java.lang.String pPrefix)
Description copied from class: GraphPanel

This method accepts a Properties object and an optional String prefix and attempts to extract configuration data from it. It complements toPizza(). If 'pPizza' is null or empty nothing happens: the method returns silently. If 'pPrefix' is not null or blank it is used as a prefix to each key. If the String sent in does not end with a dot one will be supplied automatically. All of the keys requested have default valus that match the ones on the GUI.

Under normal cirucmstances the generator instances exposed to scripts are the ones in the GUI so changes using one are reflected in the other.

Specified by:
eatPizza in class GraphPanel
Parameters:
pPizza - A java.util.Properties object containing configuration data.
pPrefix - An optional prefix to include with each key. Ignored if null or blank.
