More information on the types of URLs and their formats can be found in the URL Specification. A resource can be something as simple as a file or a directory, or it can be a reference to a more complicated object, such as a query to a database or to a search engine. The URL data type represents a Uniform Resource Locator, a pointer to a "resource" on the World Wide Web. IconĪ small fixed size picture, typically used to decorate components. When constructing a Color with an explicit alpha or getting the color/alpha components of a Color, the color components are never premultiplied by the alpha component. An alpha value of 1.0 or 255 means that the color is completely opaque and an alpha value of 0 or 0.0 means that the color is completely transparent. The alpha value defines the transparency of a color and can be represented by a float value in the range 0.0 - 1.0 or 0 - 255. Every color has an implicit alpha value of 1.0 or an explicit one provided in the constructor. The Color data type is used to encapsulate colors in the default sRGB color space. Represents a specific instant in time, with millisecond precision. This data type represents one bit of information. Use this data type for simple flags that track true/false conditions.
The Boolean data type has only two possible values: true and false. StringDoubleĪ Double data type with support for formatting patterns. BigDecimalĪn arbitrary-precision signed decimal number. As mentioned above, this data type should never be used for precise values, such as currency.
For decimal values, this data type is generally the default choice. Its range of values is beyond the scope of this discussion, but it can typically handle more than 15 decimal digits. The Double data type is a double-precision 64-bit IEEE 754 floating point. For that, you will need to use the BigDecimal type instead. This data type should never be used for precise values, such as currency. Its range of values is beyond the scope of this discussion, but it can typically handle more than 7 decimal digits. The Float data type is a single-precision 32-bit IEEE 754 floating point. Use this data type when you need a range of values wider than those provided by Integer. The Long data type is a 64-bit signed two’s complement integer. This data type will most likely be large enough for the numbers your program will use, but if you need a wider range of values, use Long instead. For integral values, this data type is generally the default choice unless there is a reason (like the above) to choose something else. The Integer data type is a 32-bit signed two’s complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive). The short data type is a 16-bit signed two’s complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The Byte data type is an 8-bit signed two’s complement integer. The treemap visualization can be exported as a 3D model in the following formats: The Parquet format stores tabular data (numbers and text) in a compressed, efficient columnar data representation. The Arrow format stores tabular data (numbers and text) in form that allow data access without serialization overhead. Microsoft Excel Workbook ( *.xls *.xlsx *.xlsm) It stores tabular data (numbers and text) in plain-text form. The tab-separated values format is a popular method of data interchange among databases and spreadsheets.
Text (Tab Delimited) ( *.txt *.tsv *.tab *.raw)
#Html treemap chart with div software#
Most spreadsheet and data management software are able to import data in this format. JavaScript Example: import * as hierarchical from m圜hart = new hierarchical.The comma-separated values (CSV) format stores tabular data (numbers and text) in plain-text form.
