私はAmchartsで折れ線グラフを作成しており、スクロールバーを使用してグラフをスクロールすることができます。理想的には、スクロールバーがjsfiddleに表示するために、私は画像のようにしたい、しかし、いくつかの奇妙な理由のために、彼らは次のように現れている：スクロールバーの画像がAmchartsに正しく表示されない
これは、このグラフのコードのJavaScriptの一部である：
var chart;
AmCharts.theme = AmCharts.themes.light;
AmCharts.ready(function() {
// SERIAL CHART
chart = new AmCharts.AmSerialChart();
chart.dataProvider = generateChartData();
chart.categoryField = "date";
chart.marginRight = 0;
chart.marginTop = 0;
chart.autoMarginOffset = 0;
chart.angle = 0;
chart.dataDateFormat = "YYYY-MM-DD";
chart.pathToImages = "https://www.amcharts.com/lib/images/";
chart.fontFamily = "Helvetica";
chart.fontSize = 14;
// AXES
// category
var categoryAxis = chart.categoryAxis;
categoryAxis.labelRotation = 60;
categoryAxis.gridPosition = "start";
categoryAxis.dashLength = 1;
categoryAxis.parseDates = true;
categoryAxis.equalSpacing = false;
categoryAxis.minorGridEnabled = true;
// categoryAxis.dateFormats = [{period:'DD',format:'MM DD YYYY'}];
categoryAxis.boldPeriodBeginning = true;
categoryAxis.markPeriodChange = false;
// value
var valueAxis = new AmCharts.ValueAxis();
valueAxis.title;
valueAxis.dashLength = 10;
chart.addValueAxis(valueAxis);
// GRAPH
var graphEnrolled = new AmCharts.AmGraph();
graphEnrolled.valueField = "value";
graphEnrolled.colorField = "color";
graphEnrolled.balloonText = "[[category]]: [[value]]";
graphEnrolled.type = "smoothedLine";
graphEnrolled.lineAlpha = 2;
graphEnrolled.fillAlphas = 0;
chart.addGraph(graphEnrolled);
var scrollbar = new AmCharts.ChartScrollbar();
scrollbar.scrollbarHeight = 5;
chart.addChartScrollbar(scrollbar);
scrollbar.graph = graphEnrolled;
var cursor = new AmCharts.ChartCursor();
cursor.cursorPosition = "mouse";
cursor.pan = true;
cursor.valueLineEnabled = true;
cursor.valueLineBalloonEnabled = true;
chart.addChartCursor(cursor);
//var graphExpected = new AmCharts.AmGraph();
//graphExpected.valueField = "value2";
//graphExpected.colorField = "color";
//graphExpected.balloonText = "[[category]]: [[value]]";
//graphExpected.type = "smoothedLine";
//graphExpected.lineAlpha = 2;
//graphExpected.fillAlphas = 0;
//chart.addGraph(graphExpected);
// WRITE
chart.exportConfig =
{
menuRight: '20px',
menuBottom: '50px',
menuItems: [{
icon:'https://www.amcharts.com/lib/3/images/export.png',
format: 'png'
}]
}
chart.write("chartdiv");
});
function addRow() {
jQuery('<div class="data-row"><input class="data-cell data-category" value="YYYY-MM-DD" type="date"/><input class="data-cell data-value" value="0" type="number" step="1"/><input class="data-cell data-value" value="0" type="number" step="1"/><input class="data-button delete-button" type="button" value="X"/></div>').appendTo('#data-table').each(function() {initRowEvents(jQuery(this));});
}
function generateChartData() {
var chartData = [];
jQuery('.data-row').each(function() {
var date = jQuery(this).find('.data-category').val();
var value = jQuery(this).find('.data-value').val();
//var value2 = jQuery(this).find('data-value').val();
if (date != '') {
chartData.push({
date: date,
value: value,
//value: value2
});
}
});
return chartData;
}
function initRowEvents(scope) {
scope.find('.data-cell')
.attr('title', 'Click to edit')
.on('keypress keyup change', function() {
// re-generate chart data and reload it in chart
chart.dataProvider = generateChartData();
chart.validateData();
}).end().find('.delete-button').click(function() {
// remove the row
$(this).parents('.data-row').remove();
// re-generate chart data and reload it in chart
chart.dataProvider = generateChartData();
chart.validateData();
});
}
jQuery(function() {
// initialize the table
initRowEvents(jQuery(document));
});
chart.addListener("rendered", zoomChart);
zoomChart();
function zoomChart(){
//chart.zoomToIndexes(chart.dataProvider.length - 40, chart.dataProvider.length - 1);
chart.zoomToIndexes(0, 20);
}
Here is the jsfiddle for this project
