Question

Добрый день!

Имеем линейную диаграмму, на основе сабжа. (http://www.chartjs.org/docs/)

Подскажите как сделать в ней линкующие точки? А точнее чтобы при нажатии на точку появлялась краткая инфа с возможность перехода к основному тексту (наподобии спотлайта)

Заранее спасибо

Есть ответвление от сборки с возможностью добавления краткой инфы.

https://github.com/Regaddi/Chart.js/tree/tooltips

Ещё рекомендую этот проект, в нём гораздо больше возможностей по созданию диаграмм.

];
series = [
{ valueField: 'conservative', name: 'Консервативный' },
{ valueField: 'aggressive', name: 'Агрессивный' },

];

$(function () {
$("#chartContainer").dxChart({
dataSource: dataSource,
commonSeriesSettings: {
type: 'StackedLine',
argumentField: 'date',
tagField: 'tag',
hoverMode: 'allArgumentPoints',
selectionMode: 'allArgumentPoints'
},
series: series,
title: 'Population: Age Structure (2000)',
argumentAxis: {
valueMarginsEnabled: false,
label: {
overlappingBehavior: 'stagger',
format: 'monthAndDay'
},
grid: { visible: true }
},
valueAxis: {
label: {
format: 'percent',
precision: 2
},
tickInterval: 0.03,
/* min: 0.01 */
},
legend: {
horizontalAlignment: 'center',
verticalAlignment: 'bottom'
},
pointClick: function (clickedPoint) {
$('#selectionSpan').html(clickedPoint.tag);
},
tooltip: {
enabled: true,
argumentFormat: 'monthAndDay',
format: 'percent',
precision: 2,
customizeText: function (e) {
return e.valueText + ' in ' + e.argumentText;
}
}
});
});
}
);

подскажите как в сделать чтобы в "tooltip" (всплывающая подсказка) показывал разницу между текущей точкой (ее значение) и предыдущей!

Т.е. если текущая точка 5.3% а предыдущая 4.7% то в tooltip'e отображалось 0.6%!
