更改迷你图工具提示条件

时间:2018-10-25 12:33:43

标签: javascript html css sparklines

我想从所需代码更改工具提示格式。在这段代码中,迷你图的工具提示指向各州,但我希望它指向月份。我也尝试过放置数组,但显示数组。我想在迷你图工具栏中的每个州显示不同的月份。

示例:应该打印一月Q1二月Q2三月Q3四月Q4,而不是打印阿拉斯加Q1。

我正在附加迷你图高位图表的代码。

Highcharts.SparkLine = function (a, b, c) {
    var hasRenderToArg = typeof a === 'string' || a.nodeName,
        options = arguments[hasRenderToArg ? 1 : 0],
        defaultOptions = {
            chart: {
                renderTo: (options.chart && options.chart.renderTo) || this,
                backgroundColor: null,
                borderWidth: 0,
                type: 'area',
                margin: [2, 0, 2, 0],
                width: 120,
                height: 20,
                style: {
                    overflow: 'visible'
                },

                // small optimalization, saves 1-2 ms each sparkline
                skipClone: true
            },

只需包括xAxis类别。然后根据需要在工具提示格式器中添加HTML。
