FusionCharts for Flex > XML by Chart Elements > Zero Plane

Zero plane is a plane, which separates the positive and negative numbers on a chart having both of them.

The zero plane appears in the column, line, and the area chart. It can be removed in the line chart but not in the column or the area chart because they use this as their base to draw. It can be removed in the line chart by setting showZeroPlane='0'.

Customizing the zero plane

The customizable attributes for the zero plane in a 2D chart are:

Attribute Name Range Description
zeroPlaneColor Color for the Zero Plane
zeroPlaneThickness In Pixels Thickness of zero plane
zeroPlaneAlpha 0-100 Alpha of zero plane
<chart zeroPlaneColor='000000' zeroPlaneThickness='1' zeroPlaneAlpha='80'....>

The attributes for the zero plane of a 3D chart are:

Attribute Name Range Description
zeroPlaneColor   Color for the Zero Plane
zeroPlaneAlpha 0-100 Alpha of zero plane
zeroPlaneShowBorder Boolean Whether to show border of zero plane
zeroPlaneBorderColor Color Sets the border color of zero plane
<chartzeroPlaneColor='FFFFFF' zeroPlaneAlpha='80' zeroPlaneBorderColor='999999'....>

Applying effects to the zero plane

We can apply effects (shadow, glow, blur, bevel) to the div lines and zero plane using STYLES. To apply any style to the zero plane, we need to apply the style to the divisional lines. Shown below is the chart that comprises of shadow for the div lines.

The XML for the above chart is as follows:

<chart showValues='0' >
    <set name='Set 1' value='100' />
    <set name='Set 2' value='-40' />
    <set name='Set 3' value='-70' />
    <set name='Set 4' value='40' />
    
    <styles>
        <definition>

            <style name='myShadow' type='shadow' angle='45' distance='3' color='000000'/>
        </definition>
        <application>
            <apply toObject='DIVLINES' styles='myShadow' />
        </application>
    </styles>
</chart>

Similarly, the other effects can be applied to the div lines & zero plane.

Animating div lines & zero plane

You can also apply animation effects to the div lines and zero plane. The following XML would cause the x-Scale of the div lines and zero plane to animate.

<chart showValues='0' >
    <set name='Set 1' value='100' />
    <set name='Set 2' value='-40' />
    <set name='Set 3' value='-70' />
    <set name='Set 4' value='40' />

    <styles>
        <definition>
            <style name='myAnim1' type='animation' param='_xScale' start
='0' duration='1'/>
        </definition>
        <application>
            <apply toObject='DIVLINES' styles='myAnim1' />
        </application>
    </styles>
