我正在使用NVD3's multiChart图表。当我在图表中添加其他区域图形时,图例似乎会向下推动图表。添加的图表越多,图表显示得越多。
请注意2屏幕截图中的Y轴如何比原始屏幕短近50%。
我尝试用CSS删除图例,但图表仍然缩短了:
.legendWrap {
display: none;
}
甚至用Javascript删除了图例,但图表仍然被破坏了:
removeElementsByClass('nv-legend');
function removeElementsByClass(className){
var elements = document.getElementsByClassName(className);
while(elements.length > 0){
elements[0].parentNode.removeChild(elements[0]);
}
}
知道如何解决这个问题吗?
我的完整drawChart功能:
function drawChart(res) {
console.log('res',res);
nv.addGraph(function() {
chart = nv.models.multiChart()
.margin({
top: 20,
right: 40,
bottom: 50,
left: 40
})
.interpolate("linear") // don't smooth out the lines
.color(d3.scale.category10().range());
chart.xAxis.tickFormat(function(d) {
return d3.time.format('%I:%M')(new Date(d));
});
chart.yAxis1.tickFormat(d3.format(',f'));
chart.yAxis2.tickFormat(function(d) {
return '$' + d3.format(',f')(d)
});
d3.select('svg#chart')
.datum(res)
.transition().duration(500).call(chart);
chart.tooltip.hidden(true);
chart.update();
d3.select('.lines2Wrap').node().parentNode.insertBefore(d3.select('.stack1Wrap').node(), d3.select('.lines2Wrap').node());
// Add top padding to xAxis timeline:
d3.selectAll('.nv-x.nv-axis > .nv-wrap.nv-axis > g > g.tick > text').each(function(d,i) {
d3.select(this).attr('dy', '1.5em');
});
d3.selectAll('.nv-x.nv-axis > .nv-wrap.nv-axis > .nv-axisMaxMin > text').each(function(d,i) {
d3.select(this).attr('dy', '1.5em');
});
nv.utils.windowResize(chart.update);
return chart;
});
}

你是对的,传说是问题的原因。您可以完全删除图例中的display: none
,而不是在CSS中设置chart = nv.models.multiChart()
.margin({
top: 20,
right: 40,
bottom: 50,
left: 40
})
.showLegend(false) // don't show the legend
.interpolate("linear") // don't smooth out the lines
.color(d3.scale.category10().range());
:
{{1}}
