Chart Padding & Margins
The following attributes help you control chart margins and paddings. Froala Charts allows you manually customize
the padding of various elements on the chart to allow advanced manipulation and control over chart
visualization. Padding in FusionCharts Suite XT is always defined in pixels, unless the attribute itself
suggests some other scale (like plotSpacePercent
, which configures the spacing using percentage
values). You can also define the chart margins. Chart Margins refer to the empty space left on the top, bottom,
left and right of the chart. That means, FusionCharts Suite XT would not plot anything in that space. It is not
necessary for you to specify any padding or margin values. FusionCharts Suite XT automatically assumes the best
values for the same, if you do not specify the same.
xAxisNamePadding
Using this, you can set the distance between the top end of x-axis title and the bottom end of data labels (or canvas, if data labels are not to be shown).
Type: Number
Range: In Pixels

labelXPadding
This attribute sets the vertical space between the x-axis labels and canvas bottom edge.

canvasLeftMargin
This attribute lets you control the space between the start of chart canvas and the start (x) of chart. In case of 2D charts, the canvas is the visible rectangular box. Using this attribute, you can control the amount of empty space between the chart left side and canvas left side. By default, the chart automatically calculates this space depending on the elements to be placed on the chart. However, if you want to over-ride this value with a higher value, you can use this attribute to specify the same. Please note that you cannot specify a margin lower than what has been calculated by the chart. This attribute is particularly useful, when you have multiple charts placed in a page and want all their canvas start position to align with each other - so in such a case, you can set same margin value (a value large enough that it does not get rejected by chart owing to it being lower than the calculated value) for all such charts in the page.

Range: In Pixels
canvasRightMargin
Like canvasLeftMargin
, this attribute lets you set the space between end of canvas and end of
chart.

value of the numberScaleUnit
to be applied to that data value. This attribute works only when
“formatNumberScale”: “1”
and the defaultNumberScale
attribute is not defined.
For example, if “numberScaleUnit”: “K, M”

Type: String
Range: Character
inThousandSeparator
In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give an error while converting to number.

This does not mean that all numbers will be displayed with a fixed number of decimal places. For instance 55 will not be displayed as 55.00 and 55.1 will not become 55.10. In order to have fixed number of decimal places attached to all the numbers, set this attribute to 1.

The rows Object and the row Object
While the dataset
object and its child object, the data
object can be used to define
the rows and columns for a heat map chart, you have to be careful about the order of the values for the rows and
columns.
The rows
object and its child object, the row
object are used to create rows and
predefine their order, enabling you to specify the data values in any order. Although the row
object has to be defined within the rows
object, rows cannot be collectively customized using the
rows
object, because it does not have any attributes of its own.
These attributes let you define the order of rows for a heat map chart.
id
Allows you to specify a unique Id for the rows. This id is used in the data
object to place the
data values in the pre-defined position.
Type: Number/String
Range:
label
Allows you to specify a label for the rows. If you do not specify the label the unique id will be displayed as the label for the rows in the chart.
Note: The label
attribute replaces the name
attribute. Previously, either
one of the attributes could be used to set the label. Support for the name
attribute has been
discontinued.
Type: String
Range:
showLabel
Allows you to show or hide the label of a particular row.

object is used then it is mandatory to use the same id which is defined in the row
object by
the id
attribute.
