我的Morris图表没有显示最后一个xkey值:
任何想法为什么?
我的数据是:
root@sama-desktop:# ls -la /sys/bus/event_source/devices
total 0
drwxr-xr-x 2 root root 0 jul 18 20:15 .
drwxr-xr-x 4 root root 0 jan 1 1970 ..
lrwxrwxrwx 1 root root 0 jan 1 1970 breakpoint -> ../../../devices/breakpoint
lrwxrwxrwx 1 root root 0 jan 1 1970 software -> ../../../devices/software
lrwxrwxrwx 1 root root 0 jan 1 1970 tracepoint -> ../../../devices/tracepoint
观点:
[{"Date":"2016-07-17","Average":0.0},{"Date":"2016-07-16","Average":0.0},{"Date":"2016-07-15","Average":4.125},{"Date":"2016-07-14","Average":0.0},{"Date":"2016-07-13","Average":0.0},{"Date":"2016-07-12","Average":0.0},{"Date":"2016-07-11","Average":0.0}]
构建它的脚本:
<script>
var surveyLastDaysChartData = @Html.Raw(Newtonsoft.Json.JsonConvert.SerializeObject(Model.SurveyLastDaysChartData));
</script>
<div class="col-lg-6">
<div class="card-box">
<h4 class="header-title m-t-0">Média dos últimos 7 dias</h4>
<div id="dsb-survey-last-days-chart" style="height: 217px;"></div>
</div>
</div><!-- end col -->

这也发生在我身上。
我不确定Morris如何计算其元素,但有时候,当它超过宽度时,它会切断x轴上的值。
我能够修复它的方式(虽然它是一个黑客)是使用他们的gridTextSize
选项并将其更改为较小的字体大小。
示例强>:
Morris.Line({
...
gridTextSize: 10,
...
});
另一种选择,如果您的应用允许缩短日期,则可以使用xLabelFormat
选项将日期解析为较小的格式。
示例强>:
var display_date = function(d) {
var month = d.getMonth() + 1,
day = d.getDate();
var formattedDay = month + '-' + day
return formattedDay; // Return "M-DD" format for date
}
Morris.Line({
...
xLabelFormat: function(x) { return display_date(x); },
...
});

标签太长时,它是Morris.js
的默认行为。您可以使用xLabelAngle
,is和角度(以度为单位)绘制x轴标签:
Morris.Line({
// ID of the element in which to draw the chart.
element: _surveyLastDaysChartId,
// Chart data records -- each entry in this array corresponds to a point on the chart.
data: surveyLastDaysChartData,
// The name of the data record attribute that contains x-values.
xkey: 'Date',
// A list of names of data record attributes that contain y-values.
ykeys: ['Average'],
// Labels for the ykeys -- will be displayed when you hover over the chart.
labels: ['Média'],
resize: true,
hideHover: 'auto',
xLabelAngle: 60, //<-- add this
ymax: 5
});
