Usage
Description
Constant | Value | Description |
---|---|---|
PixelScale | 0 | The lengths are measured in pixels. The angles are measured clockwise in degrees, with the upwards position as 0. |
XAxisScale | 1 | The lengths are measured in x-axis scale. The angles are measured clockwise in degrees, with the upwards position as 0. |
YAxisScale | 2 | The lengths are measured in y-axis scale. The angles are measured clockwise in degrees, with the upwards position as 0. |
EndPoints | 3 | The vector lengths and directions are measured as the lengths and directions between the reference points and the reference end points. |
Arguments
Argument | Default | Description |
---|---|---|
xData | (Mandatory) | An array of numbers representing the x coordinates for the reference points of the vectors. |
yData | (Mandatory) | An array of numbers representing the y coordinates for the reference points of the vectors. |
lengths | (Mandatory) | An array of numbers representing either the lengths of the vectors or the x coordinates of the reference end points, depending on lengthScale. |
directions | (Mandatory) | An array of numbers representing either the directions of the vectors or the y coordinates of the reference end points, depending on lengthScale. |
lengthScale | PixelScale | The method to specify vector lengths and directions, which must be one of the predefined constants in the table above. |
color | -1 | The color to draw the data points. -1 means that the color is automatically selected from the palette. |
name | "" | The name of the layer. The name will be used in the legend box, if one is available. An empty string means the layer has no name. |
