Highcharts reset y Axis

highcharts, javascript, reset

Solution

You can simply remove extremes from axis. In general, I would suggest using `axis.setExtremes(min, max)` instead of `axis.update(options)`. `setExtremes` should have much better performance in compare to `update`.

Code:

$('#setDefault').click(function (ev) {
    $('[data-chart]').each(function (item) {
        $(this).highcharts().yAxis[0].setExtremes(null, null);
    });
});

Problem

First, I have several charts on my page - To make it more easy to compare data within the different charts, I'm setting the maximum yAxis to the highest one that is available. Question: How do I revert the maximum I've just set without refetching the data? I'm looking for something like "autoscale" as it works if I add a maximum value of 11245, the maximum yAxis is something like 12500. I would like to restore all my charts. Demo: http://jsfiddle.net/wiesson/0p4z1mfj ``` $('#setMax').click(function (ev) { var yAxisMax = 0; $('[data-chart]').each(function (item) { var c = $(this).highcharts(); if (c.yAxis[0].max > yAxisMax) { yAxisMax = c.yAxis[0].max; } }); $('[data-chart]').each(function (item) { c = $(this).highcharts(); if (c.yAxis[0].max < yAxisMax) { c.yAxis[0].update({ max: yAxisMax }); } }); }); ```
