JSXGraph supports chart plotting. Here are some examples of possible chart types.

The Code

var board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2], axis: true});
var dataArr = [4,1,3,2,5,7,1.5,2];
        
// Line chart
function lineChart() {
    JXG.JSXGraph.freeBoard(board);
    board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2], axis: true});
    board.suspendUpdate();
    var a = board.create('chart', dataArr, {chartStyle:'line',strokeWidth:4,strokeColor:'#0000ff'});
    board.unsuspendUpdate();
};

// Line chart with cubic splines
function splineChart() {
    JXG.JSXGraph.freeBoard(board);
    board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2], axis: true});
    board.suspendUpdate();
    var a = board.create('chart', dataArr, {chartStyle:'spline',strokeWidth:4,strokeColor:'#0000ff'});
    board.unsuspendUpdate();
};

// Bar chart
function barChart() {
    JXG.JSXGraph.freeBoard(board);
    board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2], axis: true});
    board.suspendUpdate();
    var a = board.create('chart', dataArr, {chartStyle:'bar',width:0.6,labels:dataArr});
    board.unsuspendUpdate();
};

// Single chart with multiple styles
function multiStyleChart() {
    JXG.JSXGraph.freeBoard(board);
    board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2], axis: true});
    board.suspendUpdate();
    var a = board.create('chart', dataArr, {chartStyle:'bar,line,point',width:0.8,size:4,labels:dataArr});
    board.unsuspendUpdate();
};

// Two bar charts
function twoBarCharts() {
    JXG.JSXGraph.freeBoard(board);
    board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2], axis: true});
    board.suspendUpdate();
    var a = board.create('chart', [[1,3,5,7],[4,-1,3,2]], {chartStyle:'bar',width:0.8});
    var b = board.create('chart', [[2,4,6,8],[3,1,2,5]], {chartStyle:'bar',fillColor:'#C3D9FF',width:0.8});
    board.unsuspendUpdate();
};

// Bar chart with horizontal bars
function horizontalBarChart() {
    JXG.JSXGraph.freeBoard(board);
    board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2], axis: true});
    board.suspendUpdate();
    var a = board.create('chart', dataArr, {chartStyle:'bar',labels:dataArr,width:0.8,dir:'horizontal'});
    board.unsuspendUpdate();
};

// Single chart with dynamic entries
function dynamicBarChart() {
    JXG.JSXGraph.freeBoard(board);
    board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2], axis: true});
    board.suspendUpdate();
    var s = board.create('slider', [[5,-1],[8,-1], [1,1,2]], {name:'S'});
    var f = [function(){return parseFloat((s.Value()*4).toFixed(2));},
             function(){return parseFloat((s.Value()*(-1)).toFixed(2));},
             function(){return parseFloat((s.Value()*3).toFixed(2));},
             function(){return parseFloat((s.Value()*2).toFixed(2));}];
    var chart = board.create('chart', [f], {chartStyle:'bar',width:0.8,labels:f});
    board.unsuspendUpdate();
};


// Regression curve
function fitChart(deg) {
    JXG.JSXGraph.freeBoard(board);
    board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-1, 10, 11, -2], axis: true});
    board.suspendUpdate();
    var a = board.create('chart', dataArr, 
        {chartStyle:'bar,fit', degree:deg, colorArray:['#B02B2C','#3F4C6B','#C79810','#D15600'], dash:2}
    );
    board.unsuspendUpdate();
}
lineChart();
