Configuring Thermometer Gauge

FusionCharts Suite XT allows you to customize several cosmetic and functional properties for the thermometer gauge.

In this section, you will be shown how you can:

Customize the gauge fill
Customize the gauge border
Set the thermometer radius and height manually
Show/hide temperature value
Configure tick marks and values
Configure the hover effect

Customizing the Gauge Fill

A thermometer gauge with the gauge fill customized looks like this:

Given below is a brief description of the attributes used to customize the gauge fill:

Attribute Name	Description
`gaugeFillColor`	It is used to specify the hex code of the color that will be used as the fill color for the thermometer gauge, e.g. #008ee4.
`gaugeFillAlpha`	It is used to specify the transparency for the gauge fill. This attribute takes values between 0 (transparent) and 100 (opaque), e.g. 50.

Customizing the Gauge Borders

Given below is a brief description of the attributes used to customize the thermometer gauge border :

Attribute Name	Description
`showGaugeBorder`	It is used to specify whether the gauge border will be shown or hidden. Setting this attribute to `0` will hide the gauge border, setting it to `1` (default) will show the border.
`gaugeBorderColor`	It is used to specify the hex code of the color that will be used to render the entire border of the gauge, e.g. #111111.
`gaugeBorderThickness`	It is used to specify the thickness, in pixels, for the gauge border, e.g. 5.
`gaugeBorderAlpha`	It is used to specify the transparency for the gauge border. This attribute takes values between 0 (transparent) and 100 (opaque), e.g. 50.

Setting the Thermometer Radius and Height Manually

By default, the gauge automatically calculates the best thermometer radius and height based on the data you provide. You can, however, explicitly set the thermometer radius and height.

A thermometer gauge with the thermometer radius and height set manually looks like this:

Showing/Hiding the Temperature Value

By default, the current temperature value is shown below the thermometer gauge. However, you can choose to hide this value.

Given below is a brief description of the attributes used to configure the tick marks and tick values:

Attribute Name	Description
`ticksOnRight`	It is used to specify whether the tick marks and values will be rendered to the left or the right of the gauge. Setting this attribute to `0` renders the tick marks and values on the left, setting it to `1` (default) renders them on the right.
`tickMarkDistance`	It is used to specify the distance, in pixels, between the tick marks and the gauge scale, e.g. 10.
`tickValueDistance`	It is used to specify the distance, in pixels, between the tick marks and the tick values, e.g. 5.
`adjustTM`	It is used to specify whether the number of major tick marks should be automatically adjusted to ensure better distribution of the chart scale. Setting this attribute to `0` disables automatic adjustment of tick marks, setting it to `1` (default) enables it.
`majorTMNumber`	It is used to specify the number of major tick marks to be rendered, e.g. 12.
`majorTMHeight`	It is used to specify the height of major tick marks, e.g., 5
`minorTMNumber`	It is used to specify the number of minor tick marks to be rendered, e.g. 4.
`minorTMHeight`	It is used to specify the height of minor tick marks, e.g., 7.
`tickValueStep`	If you need to show only every n-th tick value, this attribute is used to specify that value.

Given below is a brief description of the attributes used to customize the tick marks’ cosmetic properties:

Attribute Name	Description
`majorTMColor`	It is used to specify hex code of the color using which the major tick marks will be rendered, e.g. #666666.
`majorTMAlpha`	It is used to specify the transparency of the major tick marks. This attribute takes values between 0 (transparent) and 100 (opaque), e.g. 50.
`majorTMThickness`	It is used to specify the thickness, in pixels, of the major tick marks, e.g. 5.
`minorTMColor`	It is used to specify hex code of the color using which the minor tick marks will be rendered, e.g. #AAAAAA.
`minorTMAlpha`	It is used to specify the transparency of the minor tick marks. This attribute takes values between 0 (transparent) and 100 (opaque), e.g. 50.
`minorTMThickness`	It is used to specify the thickness, in pixels, of the minor tick marks, e.g. 5.
