Detailed Description

Create an axis with tick marks and labels.

Date:
2001/11/13 14:17:17
Revision:
1.20

vtkAxisActor2D creates an axis with tick marks, labels, and/or a title, depending on the particular instance variable settings. To use this class, you typically specify two points defining the start and end points of the line (x-y definition using vtkCoordinate class), the number of labels, and the data range (min,max). You can also control what parts of the axis are visible including the line, the tick marks, the labels, and the title. It is also possible to control the font family, the font style (bold and/or italic), and whether font shadows are drawn. You can also specify the label format (a printf style format).

This class decides what font size to use and how to locate the labels. It also decides how to create reasonable tick marks and labels. The number of labels and the range of values may not match the number specified, but should be close.

Labels are drawn on the "right" side of the axis. The "right" side is the side of the axis on the right as you move from Point1 to Point2. The way the labels and title line up with the axis and tick marks depends on whether the line is considered horizontal or vertical.

The instance variables Point1 and Point2 are instances of vtkCoordinate. What this means is that you can specify the axis in a variety of coordinate systems. Also, the axis does not have to be either horizontal or vertical. The tick marks are created so that they are perpendicular to the axis.

void vtkAxisActor2D::ComputeRange float    inRange[2],
float    outRange[2],
int    inNumTicks,
int &    outNumTicks,

[static]
 

This method computes the range of the axis given an input range. It also computes the number of tick marks given a suggested number. (The number of tick marks includes end ticks as well.) The number of tick marks computed (in conjunction with the output range) will yield "nice" tick values. For example, if the input range is (0.25,96.7) and the number of ticks requested is 10, the output range will be (0,100) with the number of computed ticks to 11 to yield tick values of (0,10,20,...,100).

int *    size,
float    factor,
int &    stringWidth,

General method computes font size from a representative size on the viewport (given by size[2]). The method returns the font size (in points) and the string height/width (in pixels). It also sets the font size of the instance of vtkTextMapper provided. The factor is used when you're trying to create text of different size-factor is usually =1 but you can adjust the font size by making factor larger or smaller.
