charts - setonloadcallback - multi chart google chart



¿Cómo puedo adjuntar la imagen o el icono en el borde del gráfico de líneas de Google? (1)

Quiero que el gráfico de líneas se vea a continuación

o solo es posible el cuadro de secuencia de imagen?

Me gusta esto

¿Hay alguna manera posible de lograr esto?


usa el method getChartLayoutInterface

var layout = chart.getChartLayoutInterface();

para encontrar la ubicación (x, y) del punto

var xPos = layout.getXLocation(data.getValue(row, xColumn)); var yPos = layout.getYLocation(data.getValue(row, yColumn));

luego agregue la imagen manualmente y ajuste en consecuencia

google.charts.load(''current'', {packages: [''corechart'', ''line'']}); google.charts.setOnLoadCallback(drawBackgroundColor); function drawBackgroundColor() { var data = new google.visualization.DataTable(); data.addColumn(''number'', ''X''); data.addColumn(''number'', ''Y''); data.addRows([ [0, 0], [1, 10], [2, 23], [3, 17], [4, 18], [5, 9], [6, 11], [7, 27], [8, 33], [9, 40], [10, 32], [11, 35], [12, 30], [13, 40], [14, 42], [15, 47], [16, 44], [17, 48], [18, 52], [19, 54], [20, 42], [21, 55], [22, 56], [23, 57], [24, 60], [25, 50], [26, 52], [27, 51], [28, 49], [29, 53], [30, 55], [31, 60], [32, 61], [33, 59], [34, 62], [35, 65], [36, 62], [37, 58], [38, 55], [39, 61], [40, 64], [41, 65], [42, 63], [43, 66], [44, 67], [45, 69], [46, 69], [47, 70], [48, 72], [49, 68], [50, 66], [51, 65], [52, 67], [53, 70], [54, 71], [55, 72], [56, 73], [57, 75], [58, 70], [59, 68], [60, 64], [61, 60], [62, 65], [63, 67], [64, 68], [65, 69], [66, 70], [67, 72], [68, 75], [69, 80] ]); var options = { colors: [''#000000''], legend: ''none'', lineSize: 2 }; var container = document.getElementById(''chart_div''); var chart = new google.visualization.LineChart(container); google.visualization.events.addListener(chart, ''ready'', function () { var layout = chart.getChartLayoutInterface(); for (var i = 0; i < data.getNumberOfRows(); i++) { // add image above every fifth element if ((i % 5) === 0) { var xPos = layout.getXLocation(data.getValue(i, 0)); var yPos = layout.getYLocation(data.getValue(i, 1)); var whiteHat = container.appendChild(document.createElement(''img'')); whiteHat.src = ''http://findicons.com/files/icons/512/star_wars/16/clone_old.png''; whiteHat.className = ''whiteHat''; // 16x16 (image size in this example) whiteHat.style.top = (yPos - 16) + ''px''; whiteHat.style.left = (xPos) + ''px''; } } }); chart.draw(data, options); }

.whiteHat { border: none; position: absolute; }
