Description
Technical field
The present invention relates to big data technical fields, show big data in graphical user interfaces in particular to one kind
The method of collection.
Background technique
Visualization is in the gui for showing the component software (component software is also referred to as control or widget) of data, by force
The some aspects of adjusting data and de-emphasize other aspect.Visualization allows so that data are presented to the significant visual angle of user,
No matter these are the demonstrator or consumer of data.In the case where " big data ", user may need to amplify sub-fraction
Data.Data can arrange, the page and other possible coordinates are in data grids (electrical form, list, table) along row
It is existing, or in the image along x and y pixel coordinate, in Gantt chart or other charts, present in the graphic, or with this
Any other visualization format known to field.
It visualizes the component software that can be pre-compiled as in particular software development environment or they can be in operation
It generates, such as in webpage or other HTML relevant documentations, interpreted language may be used, such as JavaScript.
When creating visualization for big data, developer is likely encountered the limitation presented by target GUI.For example, counting
Show that the complete spreadsheet of 1,000,000 rows and 1,000,000 column is unpractical on calculation machine display.As electrical form will have one
Trillion cells, but modern times 8K display only has 7,680 × 4,320=33,177,600 pixels.For example, each trillion row and
The electrical form problem of column can become even worse.
Visualization-in Web browser or multi-platform application program usually is realized-is encountered with HTML and JavaScript
From the various limitations of browser itself or the browser control part utilized, for example, it is related with the maximum canvas size of display elements,
The largest amount for the integer that inside uses or available maximum memory.The scrolling function of html document object model (DOM) element
Provide further limitation.
In order to solve this problem, developer shows data subset by virtual browse or virtualization painting canvas.It is some to open
Hair personnel show a part of data series, and obtain more data when user rolls to its end.However, these methods do not have
Promising user provides good roll capability or sufficiently shields them from above-mentioned browser restricted problem.
Summary of the invention
The invention proposes the methods that one kind shows large data sets in graphical user interfaces, and wherein graphical interfaces is included in
In computer system with screen and there is the hardware for being configured to receive user's input, this method comprises:
Creation includes the visualization of the control in browser, and wherein control includes painting canvas；
Candidate canvas size is determined according to the size of large data sets；
Determine the maximum canvas size that browser is supported；
Canvas size is adjusted according to candidate canvas size and maximum canvas size；
Use at least one page in the initial data block filling painting canvas from large data sets；
Visualization, and the show scroll bars in visualization are shown on the computer screen；
User's rolling input is received, wherein user, which rolls input, can indicate long rolling or short rolling；
Determine that user rolls input and indicates long rolling or short rolling；
When determining that user rolls input expression length rolling, rolling ratio is calculated from scroll bar slide position；
When calculating rolling ratio, determine whether rolling ratio is equal to 100%；
When determining that rolling ratio is equal to 100%, using in the last one data block filling painting canvas from large data sets
Last page；
When determining rolling ratio less than 100%, with the data from the large data sets position that the size of large data sets calculates
Block fills the page in painting canvas multiplied by the ratio of rolling；With
When determining that user rolls the input short rolling of expression, for from next data block of large data sets filling painting canvas
The page.
A series of method, wherein determining that the maximum canvas size includes searching in the browser with tests
Height and the continuous setting control of width, and check whether the browser returns to the exact value of the test height and width.
The method, wherein determining that candidate's canvas size includes calculating the quantity of large data sets row multiplied by average row height
With large data sets columns multiplied by average column width.
The method, wherein determining that the size of the painting canvas includes determining the maximum canvas size and the candidate picture
Smaller in cloth size.
The method, wherein one or more adjacent datapages in the initial data block and the large data sets
Unanimously.
The method further includes that addition can receive the rolling event monitoring that user rolls input and acted to it
Device.
The method, wherein if there are any rendering data at obtained new canvas location, user rolls defeated
Enter to indicate short rolling, and if there is no rendering data at obtained new canvas location, then it represents that long to roll.
The method, wherein coarse at least 1000 times of the resolution ratio of scroll bar sliding block resolution ratio large data sets.
The method further includes the painting canvas page data abandoned no longer in the preloaded area of the painting canvas.
The method, wherein the browser supports hypertext markup language (HTML).
