betterplot

An matplotlib like api for java, continuous improving! This project was built just because plotting chart is not too easy and clear in java than in python, so i copyed the plot api in matplotlib and converted it in java.

steps

step1.

Download the prebuild packages(betterplot-api, betterplot-model, betterplot-server). Add the betterplot-model and betterplot-api packages into your own local maven repository.

step2.

Start the springboot application. java -jar betterplot-server[...].jar

step3.

Use the api supported by betterplot-api package to plot something.

examples

example01

api

public static void plot(List<? extends Object> x, List<? extends Number> y)

code

Plot.plot(Lists.listOf(2, 3, 4), Lists.listOf(4, 5, 6));

example02

api

public static void plot(List<? extends List<? extends Object>> x, List<? extends List<? extends Number>> y, String[] legend, String[] lineTypes, String title, String xLabel)

code

Plot.plot(Lists.listOf(Lists.listOf(1, 2, 3), Lists.listOf(2, 4, 5, 6), Lists.listOf(4, 5, 6, 8, 12)), Lists.listOf(Lists.listOf(3.2, 3.2, 4.5), Lists.listOf(1.1, 3.2, 4.7, 9.9), Lists.listOf(2.1, 3.2, 9.8, 12.2, 10.1)), new String[] {"y1", "y2", "y3"}, new String[] {"line", "scatter", "line"}, "multi-line-plot", "x");

api

    .y(Lists.listOf(Lists.listOf(3.2, 3.2, 4.5), Lists.listOf(1.1, 3.2, 4.7, 9.9), Lists.listOf(2.1, 3.2, 9.8, 12.2, 10.1)))
    .legend("y1", "y2", "y3")
    .lineTypes("line", "scatter", "line")
    .title("mulit-line-stream-api")
    .xLabel("x")
    .show();
