CS102A Course Project, Fall 2018:

Plotting with Dancing Bars

November 2018 @SUSTC

The goal of the project is to finish 3 programs (Task A, B, C) to plot

simple barcharts(histograms), grouped-barcharts, stacked-barcharts and

barchart animations with given tools.

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.

To ensure the continuous visual effect of the animation, you may calculate the data

for all groups (including interpolation groups) first, and then draw them seperately in

a sequence to the canvas.

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.

The project is a team work for every group with 2 or 3 students from the same lab

class. The working duration is about one month. The last submitting date and the

presentation date would be specified by the instruction of your Lab instructor in your

lab class thereafter.

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.
