chart_flutter标签/ x轴上的文本彼此重叠 [英] charts_flutter labels/text on x-axis overlapping each other

问题描述

我在flutter中使用Charts_flutter包绘制了条形图。但是x轴上的域标签彼此重叠。有什么办法可以解决这个问题？有没有办法使文本倾斜或增加图表的宽度，使它可以水平滚动？

I rendered bar chart using the charts_flutter package in flutter. But the domain label on x-axis overlap each other. Is there a way I can resolve this? Is there a way to either incline the text or increase the width of the chart so that it becomes horizontally scrollable?

我尝试搜索任何解决方案，例如labelspecs，但无法找到解决方案。这是我的代码-

I have tried searching for any solutions like labelspecs but could not reach a solution. Here's my code -

double maxheight = .80 * MediaQuery.of(context).size.height;
        var series = [
          new charts.Series(
            domainFn: (BarChartConfig barchartconfig, _) => barchartconfig.name,
            measureFn: (BarChartConfig barchartconfig, _) => barchartconfig.rowcount,
            colorFn: (BarChartConfig barchartconfig, _) => barchartconfig.color,
            id: 'Count',
            data: datacharts,
          )
        ]; 
        var chart = new charts.BarChart(
          series,
          animate: true,
          animationDuration: Duration(seconds: 2),
        );
        return SizedBox(
          height: maxheight,
          child: chart,
        );

推荐答案

@ aswani-prakash答案很好，

@aswani-prakash answer is good,

如果您希望标签可见，则只需旋转x轴标签即可。

If you want your labels visible, Then you can simply rotate x-axis labels.

BarChart(
    ...
    domainAxis: charts.OrdinalAxisSpec(
              renderSpec: charts.SmallTickRendererSpec(labelRotation: 60),
       ),
 ),
