Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
Bubble maps are usually made for two purposes, first, to observe the absolute size of certain data in a particular dimension, e.g., sales of product 7 months, number of purchases in Beijing area, etc.; second, by the relative size of the bubbles, the ranking of certain data under certain dimensions is obtained, e.g., where 20% of the product sales are ranked, where months the worst 10% of the product sales are distributed, etc.
In the existing bubble map creation method, it is disclosed that a plurality of target sections, i.e., positions or ranges of bubbles in a coordinate system, are determined according to target values, and bubbles are created within a mapping section. However, in the prior art, bubbles are only created according to the absolute size of data, so when the data distribution is not uniform or the difference of the order of magnitude of the data is large, the size of the bubbles is too large, and the ranking of the data cannot be intuitively determined from a bubble map.
In addition, the prior art does not explicitly describe how the size of the bubbles is determined; when the data is excessively concentrated in a certain interval, manual intervention is needed to redistribute the target interval until all target values fall into different target intervals, and the bubble map generation efficiency is low; further, the conventional bubble map is applicable only to a numerical cartesian coordinate system, and is not applicable to a category cartesian coordinate system and a geographical (map) coordinate system.
In order to solve the above problem, embodiments of the present invention provide a method and an apparatus for generating a bubble map, which enable a user to quickly and intuitively obtain data that the user wants to view from the bubble map, thereby improving the value of the bubble map.
Example one
An embodiment of the present invention provides a method for generating a bubble chart, as shown in fig. 1, including:
step 101: acquiring a target data sequence to be displayed, wherein the target data sequence comprises a plurality of groups of target data, and each group of target data comprises a target numerical value and at least one dimension field;
the target data to be displayed is typically stored in a relational database in the form of a two-dimensional table, with each column of data being a field. The target data can be divided into two categories, dimensions and metrics. Dimension is the angle of interest to the business, such as time, place, product type, etc., which are commonly used dimension fields. Metrics are statistics of ultimate interest to a business, and are numerical, such as sales, quantity, and so on. As shown in table 1, a, B, and C represent dimension fields, and M represents a metric field, respectively.
TABLE 1
| A | B | C | M | … |
| a1 | b1 | c1 | m1 | … |
| a2 | b2 | c2 | m2 | … |
| … | … | … | … | … |
| an | b4 | cn | mn | … |
The target data sequence to be displayed includes a plurality of sets of target data, each set of target data including fields of (a, B, C, M, …), and the like.
Step 102: determining a coordinate system of the bubble diagram, and selecting a dimension field corresponding to the target numerical value from the target data sequence according to the selected coordinate system;
the coordinate system of the bubble map includes a polar coordinate system, a cartesian rectangular coordinate system requiring two dimensions and at least one metric to generate the bubble map, and a geographic coordinate system requiring one or two dimensions and at least one metric to generate the bubble map.
Specifically, a coordinate system of the bubble map may be determined according to a business target of the user, for example, if the bubble map is required to display sales of products at a preset location in a preset time period, the selected coordinate system may be a geographic coordinate system, and after the coordinate system is determined, a dimension field corresponding to the target value is selected from the target data sequence according to a dimension required by the coordinate system.
When the coordinate system of the bubble map is a cartesian coordinate system, any one of the following may be selected from the target data sequence: at least two numerical dimensions; at least two categorical dimensions; at least one numeric dimension and at least one categorical dimension. For example, when the coordinate system of the bubble map is a numerical cartesian rectangular coordinate system, the dimension selected from the target data sequence may include at least two numerical dimension fields; when the coordinate system of the bubble graph is a Cartesian rectangular coordinate system of a category type, the dimension selected from the target data sequence can comprise at least two category type dimension fields; when the coordinate system of the bubble map is a geographic coordinate system, the selected dimension may include at least one geographic dimension, such as a dimension field including two latitudes and longitudes or a dimension field of an administrative region.
In a specific example, a method for selecting a field from a target data sequence is shown in fig. 2, and includes the following steps:
step 201: acquiring a target data sequence;
step 202: judging a coordinate system of the bubble map;
step 203: turning to step 204 when the coordinate system is a cartesian coordinate system;
step 204: two dimension fields and a metric field (i.e., a target value) are selected from the target data sequence.
Step 205: when the coordinate system is a geographic coordinate system, turning to step 206 and step 208;
step 206: when the coordinates of the geographic coordinate system are longitude and latitude, turning to step 207;
step 208: when the coordinates of the geographic coordinate system are administrative areas, go to step 209;
step 207: two latitude and longitude dimension fields and a measurement field (namely a target value) are selected from the target data sequence.
Step 209: the dimension field and the measurement field (i.e., the target value) of an administrative region are selected from the target data sequence.
Through the steps, the data required to be input for generating the bubble diagram can be determined.
Step 103: sequencing all target values in the target data sequence according to the size of the target values, and grouping the sequenced target values according to a preset grouping number, wherein the grouping results need to meet the condition that the target values with the same value are positioned in the same group;
specifically, as shown in fig. 3, step 103 may include the following steps:
step 301: sequencing all target values in the target data sequence according to the size of the target values to obtain a first target value sequence;
step 302: merging the target values with the same value to obtain a second target value sequence, and recording the number k of the target values with the same value, wherein k is a positive integer;
step 303: generating a third sequence according to the second target numerical value sequence, wherein elements in the third sequence correspond to target numerical values in the second target numerical value sequence one by one, and the elements in the third sequence are k values of the corresponding target numerical values in the second target numerical value sequence;
step 304: grouping the elements in the third sequence according to a preset grouping number p, wherein the sum of the first p-1 groups of elements is equal to q, q is equal to n/p and rounded downwards, n is the number of target values, and p is an integer greater than 1;
step 305: and obtaining a grouping result of the target numerical value according to the grouping result of the third sequence and the corresponding relation between the elements in the third sequence and the target numerical value.
Since the metric field (i.e. the target value) is of the numeric typeTherefore, all the target values can be sorted according to the size of the target values to obtain the first target value sequence. For example, the selected metrics field includes: m is1,m2,…,mnThe first target value sequence M ═ M can be obtained by sorting the values from small to large1,m2,…,mnN for the number of elements of the first sequence of target values.
Traversing the first target numerical value sequence, wherein target numerical values with the same value exist, the number of the target numerical values with different values is d, and merging the target numerical values with the same value in the first target numerical value sequence to obtain a second target numerical value sequence M '═ M'1,m’2,…,m’dD is the number of elements of the second target numerical value sequence, and the number k of target numerical values with the same value is recorded at the same time, so that the target numerical values can be conveniently grouped in the subsequent steps.
For example, the original target value sequence is a target value sequence comprising 10 elements:
{71，23，26，85，121，26，17，24，51，71}
the first target numerical value sequence obtained by sequencing is as follows:
M＝{17，23，24，26，26，51，71，71，85，121}；
the number of the target values with different values is 8, and the second target value sequence obtained after the target values with the same values are combined is as follows:
where, the number k corresponding to the target value 17 is 1, the number k corresponding to the target value 23 is 1, the number k corresponding to the target value 24 is 1, the number k corresponding to the target value 26 is 2, the number k corresponding to the target value 51 is 1, the number k corresponding to the target value 71 is 2, the number k corresponding to the target value 85 is 1, and the number k corresponding to the target value 121 is 1.
And then grouping the target numerical values, wherein the grouping aims to divide the target numerical value sequence into different gears as much as possible according to the grouping number input by a user, and the grouping principle is that the same target numerical value must fall into the same gear. When the number of groups input by a user is p (1< p < ═ d), the number of elements in each group is rounded down to n/p, namely the number q of elements in each group is floor (n/p).
First, a sequence (i.e., a third sequence) composed of k values needs to be generated according to the sequence M ', each element in the third sequence corresponds to an element in the sequence M ', and each element in the third sequence is a k value corresponding to an element in the sequence M '. Then, finding the quantiles for dividing the sequence into p equal parts, wherein the number of the quantiles is p-1, the number of elements before each quantile is q, sequentially, firstly positioning to the first quantile, finely adjusting the positions of the quantile according to the number of the elements, then positioning to the second quantile until the quantile is p-1, dividing the sequence into p secondary sequences, wherein each secondary sequence is a group of target values, and finishing the grouping of the target values, and the sequence M' is, for example:
M’＝{17，23，24，26，51，71，85，121}
generating a third sequence consisting of k is:
{1，1，1，2，1，2，1，1}
assuming that the number p of user input packets is 3, the number q of elements per group is floor (10/3) is 3, and the result of grouping the sequence of k is:
{1，1，1}{2，1}{2，1，1}
and restoring the grouping result into a grouping result of a target numerical value, wherein the grouping result of the target numerical value is as follows:
M1’＝{17,23,24}M2’＝{26,26,51}M3’＝{71,71,85,121}。
step 104: determining the bubble radius of each group of target values according to the group number and the bubble radius base number, wherein each group of target values corresponds to the same bubble radius;
the bubbles are not one-dimensional visual graphs, and absolute numerical values are difficult to visually represent, so that the target numerical values are grouped by utilizing the relative numerical value relationship represented by the bubbles, and each group of target numerical values corresponds to the same bubble radius, so that a user can visually distinguish the size and the grading relationship of the target numerical values in a proper interval range.
Specifically, as shown in fig. 4, step 104 includes the following steps:
step 401: calculating a bubble radius base number;
in this embodiment, the bubble radius base c is calculated based on the pixels included in the rectangular chart area displaying the bubble map, so that the bubble radius of the bubble map can be calculated on a pixel basis, and there is an advantage that the bubble radius does not change in proportion with expansion and contraction.
First, the size of a rectangular chart area displaying a bubble chart, which is input by a user, is received, the length of the rectangular chart area is X, the height of the rectangular chart area is Y, and the rectangular chart area is in pixel units.
The calculation formula of the bubble radius base c is as follows: and c is (X + Y)/2n, wherein n is the number of elements in the first target numerical sequence. The bubble radius base number c is a median value for grouping the sizes of the bubble radii, and is also a base number for performing the bubble radius mapping.
Step 402: determining a value interval of the bubble radius by taking the bubble radius base number as a unit;
first, the maximum and minimum values of the bubble radius need to be set to determine the range of the mapping. If the bubble radius is too small, the user is not easy to observe, and if the bubble radius is too large, the bubble radius is easy to exceed the chart range, so that a reasonable value interval of the bubble radius needs to be set. Through tests, when the radius of the bubbles is changed between 0.5c and 1.5c, the sizes of the bubbles are proper, the sizes of the adjacent bubbles are easy to distinguish, the bubbles cannot exceed the range of a chart because of being too large, and the bubbles cannot be easily observed because of being too small. Certainly, the value interval of the bubble radius is not limited to [ 0.5c, 1.5c ], and may be changed according to the user's needs, for example, when the number of packets is large (exceeds 7 groups), the value interval of the bubble radius may be expanded.
Step 403: sequentially taking p bubble radius values in the value interval according to the group number p, wherein the 1 st bubble radius value is the minimum value of the value interval, the p-th bubble radius value is the maximum value of the value interval, and the difference values between the adjacent bubble radius values are equal;
according to the grouping number, the value interval of the bubble radius is evenly divided into p groups and p bubble radius values are obtained, for example, when the grouping number is 3, three bubble radius values are respectively 0.5c, c and 1.5c, and when the grouping number is 4, four bubble radius values are respectively 0.5c,5/6c,7/6c and 1.5c, and so on.
Step 404: and sequencing p groups of target values in a descending order, wherein the radius of the bubble of the mth group of target values is the mth bubble radius value, and m is an integer which is greater than or equal to 1 and less than or equal to p.
And respectively corresponding the p groups of target values with the p bubble radius values in a one-to-one manner from small to large.
Assuming that the user draws a bubble map in an 800 × 500 area, where X is 800, Y is 500, and the number n of known target values is 10, and the bubble radius base is calculated to be (800+500)/2 × 10 is 65(px), the value intervals of the bubble radius are [ 0.5 × 65, 1.5 × 65 ] - [ 32.5, 97.5 ], the number of packets input by the user is 3, and further three bubble radius values are 32.5px, 65px, and 97.5px, and 3 sets of target values are respectively in one-to-one correspondence with 3 bubble radius values in the order from small to large, M can be obtained1' {17,23,24} corresponds to a bubble radius value of 32.5px, M2' {26,26,51} corresponds to a bubble radius value of 65px, M3The value of the radius of the bubble is 97.5px for' {71,71,85,121 }.
Step 105: generating a bubble map in the coordinate system according to the determined bubble radius.
The bubble graph is generated by determining the center point of the bubble and the radius of the bubble, the center point of the bubble can be determined through the dimension sequence, and the center point of the bubble can be determined by using the prior art, which is not described herein again. In addition, the size of the bubble radius is obtained through the above steps, and an Application Programming Interface (API) is combined with the third party icon library (with the position and size of the bubble as parameters), so that the bubble map can be drawn in the coordinate system.
The target values in the same group are mapped into bubbles with the same size, so that a user can intuitively determine the target values in the same level and the target values in different levels from the bubble map.
Specifically, as shown in fig. 5, step 105 includes the steps of:
step 501: obtaining the dimensionality corresponding to the target numerical value;
step 502: acquiring a bubble radius corresponding to a target numerical value;
step 503: and determining the center point of the bubble according to the dimension corresponding to the target numerical value, and generating the bubble according to the center point of the bubble and the radius of the bubble.
In a specific example, assume that the dimension sequences a and B are:
a ═ 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months };
b ═ beijing, shanghai, guangzhou, shenzhen, chengdu, wuhan, shenyang, uniujue, xi' an, nanjing };
M＝{71，23，26，85，121，26，17，24，51，71}；
the generated bubble map is specifically shown in fig. 6.
