我如何重置Highcharts系列的风格? [英] How can I reset the styles given to series in Highcharts?
问题描述
我使用Highcharts将一些图表呈现给我的网站。有时,我需要从图表中删除所有系列,并向图表添加一些新的系列,因为我通过ajax请求了一些新数据。
我现在正在做这个方式:
var chart = $('#container')。highcharts();
while(chart.series.length){
chart.series [0] .remove();
chart.addSeries({
data:[144.0,176.0,29.9,71.5,106.4,129.2,135.6,148.5,216.4,194.1,95.6,54.4]
});
chart.addSeries({
data:[129.2,106.4,135.6,95.6,54.4,148.5,144.0,176.0,29.9,71.5,216.4,194.1]
});
chart.addSeries({
data:[106.4,129.2,135.6,148.5,144.0,176.0,29.9,71.5,194.1,95.6,54.4,216.4]
});
但我的问题是,新系列与第一个系列颜色完全不同。
我无法简单地替换数据,因为系列数量可能会发生变化,所以我必须删除所有系列并添加新系列。
我怎样才能存档新系列的风格如同被替换的风格? (在我的小提琴中,新系列的颜色应该是lightblue,darkblue和第三种颜色。)
测试用例
我创建了一些测试用例来阐明我面临的问题。最上面的图表是它应该看起来的样子,底部图表是它的外观。我希望他们一样!
一个解决方案需要处理所有这些情况!
我在GitHub的pull请求中找到了解决方案( https://github.com /highslide-software/highcharts.com/pull/203 )。
删除系列后,您只需重置Highcharts颜色计数器。
这些符号也有一个计数器。
更新:从版本4.0.3开始,计数器名称已更改:
var chart = $('#container')。highcharts();
while(chart.series.length){
chart.series [0] .remove();
}
chart.colorCounter = 0;
chart.symbolCounter = 0;
chart.addSeries({
data:[144.0,176.0,29.9,71.5,106.4,129.2,135.6,148.5,216.4,194.1,95.6,54.4]
}) ;
chart.addSeries({
data:[129.2,106.4,135.6,95.6,54.4,148.5,144.0,176.0,29.9,71.5,216.4,194.1]
});
chart.addSeries({
data:[106.4,129.2,135.6,148.5,144.0,176.0,29.9,71.5,194.1,95.6,54.4,216.4]
});

(版本4.0.3之前,您必须使用chart.counters .color = 0和chart.counters.symbol = 0)
I am using Highcharts to render some graphs to my website. Sometimes, I need to remove all series from the chart and add some new series to the chart, because I requested some new data through ajax.
I am currently doing it this way:
var chart = $('#container').highcharts();
while(chart.series.length) {
chart.series[0].remove();
}
chart.addSeries({
data: [144.0, 176.0, 29.9, 71.5, 106.4, 129.2, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
});
chart.addSeries({
data: [129.2, 106.4, 135.6, 95.6, 54.4, 148.5, 144.0, 176.0, 29.9, 71.5, 216.4, 194.1]
});
chart.addSeries({
data: [106.4, 129.2, 135.6, 148.5, 144.0, 176.0, 29.9, 71.5, 194.1, 95.6, 54.4, 216.4]
});
This you can see in this fiddle.
But my problem is that the new series get completely different colors from the first ones.
I can not simply replace the data, because the number of series is likely to change, so I have to remove all series and add the new ones.
How can I archive that the new series are styled like the replaced ones? (In my fiddle, the new series should have the colors lightblue, darkblue and some third color.)
Test cases
I have created some test cases to clarify the problem I am facing. The top chart is how it should look and the bottom chart is how it actually looks. I want them to be the same!
- Remove two series and add two series
- Remove two series and add three series
- Remove three series and add two series
A solution would need to work with all these cases!
I found the solution in a pull request on GitHub (https://github.com/highslide-software/highcharts.com/pull/203).
You just need to reset Highcharts color counter after deleting the series. There is also a counter for the symbols.
UPDATE: From version 4.0.3 and above the name of the counters has changed:
var chart = $('#container').highcharts();
while(chart.series.length) {
chart.series[0].remove();
}
chart.colorCounter = 0;
chart.symbolCounter = 0;
chart.addSeries({
data: [144.0, 176.0, 29.9, 71.5, 106.4, 129.2, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
});
chart.addSeries({
data: [129.2, 106.4, 135.6, 95.6, 54.4, 148.5, 144.0, 176.0, 29.9, 71.5, 216.4, 194.1]
});
chart.addSeries({
data: [106.4, 129.2, 135.6, 148.5, 144.0, 176.0, 29.9, 71.5, 194.1, 95.6, 54.4, 216.4]
});
Live example: http://jsfiddle.net/juuQs/18/
(Prior to version 4.0.3 you must use chart.counters.color = 0 and chart.counters.symbol = 0)
