Description

Task A (Enhancing HistogramA): Given HistogramA.java and
HistogramATest.java, use two given tools, javax.json (glassfish implementation javax-json-1.1.4.jar is given, refer https://www.oracle.com/technetwork/articles/java/json-1973242.html) and Stddraw (Stddraw.java, Stddraw.html are given), to draw a color histogram with annotations and scales by reading a Json-formatted file with data and specific drawing formats.
Based-on the given programs, add the following features:
A.1 All the parameter values in the formats part and the minvalue setting of the data part could be either customized by the given values or by default values.
A.2 Optimize the setting values of the default parameters in order to get a professional outlook for the histogram using default values. (Refer RGB color selection:
https://www.rapidtables.com/web/color/RGB_Color.html )
A.3 Complete plotRightRuler();
A.4 To achieve better outlook, various types of fonts and location setting for all kinds of texts in the higtogram should be customized by the given parameters in the input Json file and should also work with default values.
Three sample output of HistgramA are given in the project reference.
Task B (Grouped-Barcharts and Stacked-Barcharts): Based on the Task A, write a program to read a Json formatted data and drawing specific requirements file and draw color multi-dimensional (grouped) histograms or stacked barchats (drawing categories based on the input parameter) with scales, annotations and lengends. Four sample drawing barcharts are given as examples in the project reference.
Task C (Dancing Bars — Animation of Dynamic Barcharts): View the given video, write a program to implement an animation of dynamic barcharts with sorted data according to the data and drawing parameters reading from a Json file.
Tips: 1) Use StdDraw’s show(), pause(), enabledoublebuffering(), disabledoublebuffering () to implement animation. 2) Between two sets of data, linear interpolation can be used to calculate multiple sets of intermediate evolution data, each time show a set (if necessary, sort or adjust the order), pause a number of milliseconds, and continue to draw the next set of data.

All the data used in plotting should be came from real world and it is recommended to use the latest domestic and international statistics data published by the National Bureau of Statistics (http://data.stats.gov.cn/index.htm).
For Task A, at least 4 sets of data are required. For Task B, at least 4 sets of data are required (at least 2 sets for grouped barcharts, and at least 2 sets for stacked barcharts).
For Task C, at least 2 sets of data are required for barchart animations.

Every group should explicitly describe the contribution rate for the team project work for every group member. The project score for every student is a combination of the team work score gained and one’s contribution rate.
