# Chart Element Parameters

Here are parameters for plotting various chart elements.

## MapAxis

name

Name of mapping table

logicalData

The sequence composed of logical coordinate values of a logical axis.

physicalData

The mapping values corresponding to the logicalData, which are in a one-to-one relation to the logicalData. They are usually in the form of a sequence composed of the appearance property values.

## NumericAxis

name

Numeric axis name.

visible

Show or hide axis

location

The position where a numeric axis will be plotted. You can set the axis as vertical axis, horizontal axis, polar axis, or radial axis.

is3D

Whether the axis is 3-dimensional or not. If the 3D property is adopted for at least one coordinate axis in the coordinate system on canvas, then the other coordinate axes in the current coordinate system will take on the 3D effect accordingly in chart plotting.

threeDThickRatio

The thickness ratio of 3D axes in a 3D chart. This parameter determines the 3D Thickness, which refers to the length of edges pointing towards the observer. The threeDThickRatio takes effect on condition that there is no enum axis in the coordinate system on canvas, and the axis 1 is the numeric axis. The default maximum 3D depth is 60 pixels.

To compute the overall 3D thickness based on the 3D thickness ratio of axis 1, use 3D Thickness Ratio * Canvas Height. If the ratio is greater than 1, then it represents the absolute pixel value. In addition, the chart will be auto-plotted with 60 pixels if the 3D thickness is greater than 60.

Whether or not the value range of the coordinate axis will be computed automatically according to the coordinates of a point. If set as true, it will set automatically the value range of numeric axis for the computation according to the coordinates of the coordinate axis.

maxValue

Maximum on the customized numeric axis. To get this, the autoCalcValueRange must be set to false, and thus the system will not compute the axis range automatically.

minValue

Minimum on the customized numeric axis. To get this, the autoCalcValueRange must be set to false, and thus the system will not compute the axis range automatically.

scaleNum

The number of scales displayed on the customized numeric axis. The autoCalcValueRange must be set to false, and thus the system will not compute axis range automatically.

format
