The underlying JavaScript code

var board = JXG.JSXGraph.initBoard('jxgbox', {axis:false, boundingbox:[-5, 5, 5, -5]});

// Horizontal axis with polar grid lines
var ax1 = board.create('axis', [[0,0], [1,0]], {
    ticks: {
        type: 'polar',         // Polar grid
        label: {               // Place the labels centered on the grid lines 
            offset:[0, -3], 
            anchorX: 'middle', 
            anchorY: 'top'
        }
    }
});

// Vertical axis with horizontal ticks
var ax2 = board.create('axis', [[0,0], [0,1]], {
    ticks: {
        majorHeight: 0,        // Do not show the grid lines 
        tickEndings: [1, 0],   // Let the ticks point to the left
        label: {               // Position of the labels
            visible: true, 
            offset: [-6, 0], 
            anchorY: 'middle', 
            anchorX: 'right'
        }
    }
});
