Flash Chart Documentation

CalcXML's calculators have the ability to create charts either as image files or as Flash animated files. You can specify which type of chart you would like created by setting the chartLibrary attribute of the root <calcxmlRequest> element. The two valid values for this attribute are "image" and "flash". This documentation discusses the options available to you when using the "flash" option.

You can control the "look-and-feel" of the Flash chart by passing in some information as part of your <calcxmlRequest>. <calcxmlRequest> has a child element called <flashChart>. You can review the schema of this child element here - <flashChart> schema.

Attributes are passed in as name/value pairs. You can include as many attributes as you would like. Here is a simple example of a <flashChart> element.

<calcxmlRequest>
. . .
  <flashChart>
    <threeD>1</threeD>
    <chartWidth>500</chartWidth>
    <chartHeight>300</chartHeight>
    <chartAttributes>
      <attribute name="caption" value="My Chart Title"/>
      <attribute name="showBorder" value="1"/>
      <attribute name="borderColor" value="CCCCCC"/>
    </chartAttributes>
  </flashChart>
. . .
</calcxmlRequest>

Notice the <chartAttributes> element has three child <attribute> elements and each of these <attribute> elements specifies a name and a value. The available names and values are shown in the tables below.

The Flash charts already have many of the attributes set by default. It is suggested that prior to passing in your own attributes, you first see how the default chart is rendered. If there is something that you would like changed in the default chart, then go ahead and pass in the appropriate attributes and values to make the change.


 Flash Chart Attributes
Functional Attributes
These attributes let you control a variety of functional elements on the chart. For example, you can opt to show/hide data labels, data values, y-axis values. You can also set chart limits and extended properties.

Attribute Name Type Range Description

    formatNumberScale Boolean 0/1 Configuration whether to add K (thousands) and M (millions) to a number after truncating and rounding it - e.g., if formatNumberScale is set to 1, 1043 would become 1.04K (with decimals set to 2 places). Same with numbers in millions - a M will added at the end. For more details, please see Advanced Number Formatting section.
    defaultNumberScale String The default unit of the numbers that you're providing to the chart. For more details, please see Advanced Number Formatting section.
    numberScaleUnit String Unit of each block of the scale. For more details, please see Advanced Number Formatting section.
    numberScaleValue String Range of the various blocks that constitute the scale. For more details, please see Advanced Number Formatting section.
    numberPrefix String Character Using this attribute, you could add prefix to all the numbers visible on the graph. For example, to represent all dollars figure on the chart, you could specify this attribute to ' $' to show like $40000, $50000. For more details, please see Advanced Number Formatting section.
    numberSuffix String Character Using this attribute, you could add suffix to all the numbers visible on the graph. For example, to represent all figure quantified as per annum on the chart, you could specify this attribute to ' /a' to show like 40000/a, 50000/a.

In XML, if you specify such values, it will give a error while converting to number. So, Flash charts accepts the input decimal and thousand separator from user, so that it can covert it accordingly into the required format. This attribute lets you input the decimal separator. For more details, please see Advanced Number Formatting section.
    inThousandSeparator String Character In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give a error while converting to number. So, Flash charts accepts the input decimal and thousand separator from user, so that it can covert it accordingly into the required format. This attribute lets you input the thousand separator. For more details, please see Advanced Number Formatting section.
    decimals Number 0-10 Number of decimal places to which all numbers on the chart would be rounded to.

    Chart Padding & Margins
    The following attributes help you control chart margins and paddings.

    You can manually customize the padding of various elements on the chart to allow advanced manipulation and control over chart visualization. Padding is always defined in pixels, unless the attribute itself suggests some other scale (like plotSpacePercent).

    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, Flash charts wouldn't plot anything in that space.

    It's not necessary for you to specify any padding/margin values. The best values are automatically assumed for the same, if you do not specify the same.

    Attribute Name Type Range Description
    captionPadding Number In Pixels This attribute lets you control the space (in pixels) between the sub-caption and top of the chart canvas. If the sub-caption is not defined, it controls the space between caption and top of chart canvas. If neither caption, nor sub-caption is defined, this padding does not come into play.
    chartLeftMargin Number In Pixels Amount of empty space that you want to put on the left side of your chart. Nothing is rendered in this space.
    chartRightMargin Number In Pixels Amount of empty space that you want to put on the right side of your chart. Nothing is rendered in this space.
    chartTopMargin Number In Pixels Amount of empty space that you want to put on the top of your chart. Nothing is rendered in this space.
    chartBottomMargin Number In Pixels Amount of empty space that you want to put on the bottom of your chart. Nothing is rendered in this space.
