Coordinate value will carry out visualization presentation in default painting canvas of the target 2-D data in screen..
In this example, successfully it is mapped to as illustrated in FIG. 3 according to mode illustrated above when by target 2-D data (X, Y)
After in the spiral shape two-dimensional coordinate system gone out, now the target 2-D data can be expressed as the form of (θ, radius), so that
The target 2-D data can be labeled in spiral shape two-dimensional coordinate system as illustrated in FIG. 3 by client, be carried out further
Visualization is presented.
Wherein, above-mentioned client for above-mentioned target 2-D data when carrying out visualization presentation, and user can be by upper
Screen of the client in presentation device (the such as one PC main frame for showing visualization result) is stated, pre-configured one is preset
The painting canvas of size；Wherein, the size user of painting canvas can be configured based on actual demand.
When for target 2-D data (X, Y) is successfully mapped into spiral shell as illustrated in FIG. 3 according to mode illustrated above
Revolve after shape two-dimensional coordinate system, the form for being finally expressed as (θ, radius), above-mentioned client can be by the target 2-D data base
It is presented in default visualization presentation mode in the painting canvas.
Wherein, it is complete with spiral shape two-dimensional coordinate system as illustrated in FIG. 3 due to the screen coordinate system of above-mentioned presentation device
Difference, therefore before visualization presentation is carried out for the target 2-D data, in addition it is also necessary to by the target 2-D data (θ,
Radius), the transverse axis coordinate value X ' and ordinate of orthogonal axes value Y ' corresponding to screen coordinate system are converted to.
In a kind of embodiment shown, above-mentioned client can obtain the central point of above-mentioned painting canvas first, correspond to
The coordinate (xCenter, yCenter) of screen coordinate system, and by default helical coefficient a, and the target 2-D data (θ,
Radius mapping polar angle value θ) is as calculating parameter, and the polar equation for being updated to Archimedes spiral calculates the mapping polar angle
The corresponding pole axis length r of value θ.
After mapping polar angle value θ corresponding pole axis length r are calculated, if necessary to further by the target 2-D data
Transverse axis coordinate value X ' and ordinate of orthogonal axes value Y ' of (θ, the radius) conversion corresponding to screen coordinate system, then will can be somebody's turn to do first
The coordinate value (θ, radius) that target 2-D data corresponds to above-mentioned spiral shape two-dimensional coordinate system is converted to corresponding to polar coordinate system
Coordinate value, then further according to the standard handovers relation between polar coordinates and screen coordinate system, to complete target 2-D data
(θ, radius) is converted to the Coordinate Conversion of (X ', the Y ') corresponding to screen coordinate system；
Wherein, due to based on above-mentioned mapping polar angle value θ, and the above-mentioned pole axis length r calculated, polar coordinates table can be used
It is θ, and above-mentioned mapping brachium radius to show a polar angle being located on the helix of above-mentioned spiral shape two-dimensional coordinate system
For 0 mapping point (θ, r)；And the mapping point (the θ, r), with above-mentioned target 2-D data (θ, radius) correspondence under polar coordinate system
Compared in the coordinate value of polar coordinate system, polar angle value θ does not change, and pole axis length be r and above-mentioned mapping brachium radius it
With, therefore above-mentioned target 2-D data (θ, radius) can be expressed as (θ, r+ corresponding to the coordinate value of polar coordinate system
radius)；
For example, as shown in figure 3, the length that the corresponding pole axis length r of mapping polar angle θ are line segment OQ, the mapping brachium of P points
Radius be line segment QP length, P points correspond to polar coordinate system pole axis length for line segment OQ and line segment QP length sum (i.e.
OP length), then P points, which are based on polar coordinate system, can be expressed as (θ, r+radius).
When above-mentioned client by above-mentioned target 2-D data correspond to above-mentioned spiral shape two-dimensional coordinate system coordinate value (θ,
Radius) be converted to after the coordinate value (θ, r+radius) corresponding to polar coordinate system, now above-mentioned client can be based on above-mentioned
The center point coordinate (xCenter, yCenter) of painting canvas, and the transformational relation between polar coordinate system and the screen coordinate system,
The coordinate value (θ, r+radius) that the target 2-D data corresponds to polar coordinate system is converted to corresponding to the screen coordinate system
Coordinate value (X ', Y '), so that most the mapping polar angle value θ of the target 2-D data (θ, radius) is converted to corresponding to screen at last
The transverse axis coordinate value X ' of coordinate system, and the mapping brachium radius of the target 2-D data (θ, radius) is converted into correspondence
In the ordinate of orthogonal axes value Y ' of screen coordinate system；
For example, so that screen coordinate system is cartesian coordinate system as an example, polar angle value θ and pole axis length p, with cartesian coordinate system
Transverse axis coordinate value X and ordinate of orthogonal axes value Y between transformational relation, be usually：
X=pcos θ；
Y=psin θ；
Therefore, in the case where considering the coordinate (xCenter, yCenter) of central point of above-mentioned painting canvas, above-mentioned conversion is closed
System can be expressed as：
X '=xCenter+cos (θ) (r+radius)
Y '=yCenter+sin (θ) (r+radius)
Above-mentioned client can be by the center point coordinate (xCenter, yCenter), and the target 2-D data
Corresponding to the coordinate value (θ, r+radius) of polar coordinate system, the expression formula of above-mentioned transformational relation is substituted into as parametric variable, so that it may
To calculate the transverse axis coordinate value X ' that the mapping polar angle value θ of target 2-D data (θ, radius) corresponds to screen coordinate system, with
And the mapping brachium radius of target 2-D data (θ, radius) corresponds to the ordinate of orthogonal axes value Y ' of screen coordinate system.
Expression formula more than is visible, and target 2-D data is being corresponded to the coordinate of above-mentioned spiral shape two-dimensional coordinate system
When value (θ, radius) is converted to coordinate value (X ', the Y ') corresponding to screen coordinate system, transverse axis coordinate value X ' and ordinate of orthogonal axes
Value Y ' value size, will be together decided on by above-mentioned mapping polar angle θ and mapping brachium radius value.
In this example, when the mapping polar angle value θ for calculating target 2-D data (θ, radius) corresponds to screen coordinate system
Transverse axis coordinate value X ', and the mapping brachium radius of target 2-D data (θ, radius) corresponds to the vertical of screen coordinate system
After axial coordinate value Y ', above-mentioned target 2-D data can be expressed as (X ', Y ') in screen coordinate system, and now above-mentioned client can
So that target 2-D data (X ', Y ') is labeled in screen coordinate system according to specific visualization presentation mode, visualized
