我试图在angular2中绘制一个zing图表。我的图表就是这样的。
虽然我希望我的图表看起来像下面提供的图表,但是x轴的最小值和最大值会自动调整以适应图表的面积和水平宽度。
我该怎么做呢?我按照这些链接但无法获得所需的结果。你能指出我哪里错了吗? https://www.zingchart.com/docs/tutorials/chart-elements/configure-chart-scales/#scale-formatting 我给绘制图表的选项如下:
this.charts = [{
id : 'chart-1',
data : {
'type' : 'area',
'scaleX': {
'label': {'text': 'Price'}
},
'scaleY': {
'label': {'text': 'Cumulative Volume'}
},
'plotarea': {
'adjust-layout': true /* For automatic margin adjustment. */
},
'scale-x': {
'auto-fit': true,
'min-value': minValue,
'max-value': maxValue,
'decimals': 2
},
'series': [
{ 'values': this.bidArray },
{ 'values': this.askArray }
],
},
height: 300,
width: 600
}];
}
编辑1: bidArray 和 askArray 属于数组格式数组。
答案 0 :(得分:3)
您无需将属性auto-fit
设置为true。这适用于已应用缩放的图表。
您无需设置属性min-value
或max-value
即可自动调整x轴。它默认会这样做。
问题可能在于您没有提供任何信息的图表的一部分。您的数据如何绘制?什么是值数组?阵列数组?
发布完整的图表JSON,我将为您提供演示工作。由于您的图表是动态的,您可以通过右键单击图表,单击查看源选项,然后从已解析的JSON 选项卡复制内容来获取渲染JSON。
对以下第一篇评论作出回应的新答案:
数组数组不会自动适合scaleX上的图形宽度。原因是你要求绘制比单维数组更具体的东西。因此,您可以设置minValue
和maxValue
。
主要问题是step
值。由于您定义的步骤不如minvalue
或maxvalue
中的值精确,因此必须使其匹配相同的精度。例如,你输入两个小数,execpt你的步骤设置为step:.2
,其精度只有一位小数。将精度更改为两个。 step:.01 || .02
以获得您想要的结果。
一个简短的说明。您有两个scale-x
个对象。它们在内部合并,但这很危险,因为较低的一个将覆盖第一个。如果你有一个大的JSON,这就变得更难调试。
