是否有可能将价值标签放在酒吧上,以便他们站在他们的身边？
如果我设置酒吧对齐：“center”,酒吧上的标签是关闭的,不居中.
<script type="text/javascript">
$(function() {
var data = [<?PHP echo $data; ?>];
$.plot("#<?PHP echo $target; ?> .chart-placeholder",data,{
series: {
color: "rgb(57,137,209)",bars: {
show: true,// align: "center",barWidth: .8,fill: 1
},valueLabels: {
show: true,showAsHtml: true,align: "center"
}
},grid: {
aboveData: true,hoverable: true,borderWidth: 0
},xaxis: {
mode: "categories",tickLength: 0,labelAngle: -45,showAsHtml: true
},yaxis: {
show: false,tickLength: 0
},});
});
</script>
解决方法
插件让你失望了只要自己做,生活就这么简单了.这是flot的优势,紧凑的代码,让你的方式…
// draw initial plot
// notice no categories plugin either,why?
// Because it's easier to do it yourself...
var series = {data: [[0,5.2],[1,3],[2,9.2],[3,10]],lines: {show: false},bars: {show: true,barWidth: 0.75,align:'center'}}
var somePlot = $.plot("#placeholder",[ series ],{
xaxis: {
ticks: [[0,"One"],"Two"],"Three"],"Four"]]
}
});
// after initial plot draw,then loop the data,add the labels
// I'm drawing these directly on the canvas,NO HTML DIVS!
// code is un-necessarily verbose for demonstration purposes
var ctx = somePlot.getCanvas().getContext("2d"); // get the context
var data = somePlot.getData()[0].data; // get your series data
var xaxis = somePlot.getXAxes()[0]; // xAxis
var yaxis = somePlot.getYAxes()[0]; // yAxis
var offset = somePlot.getPlotOffset(); // plots offset
ctx.font = "16px 'Segoe UI'"; // set a pretty label font
ctx.fillStyle = "black";
for (var i = 0; i < data.length; i++){
var text = data[i][1] + '';
var metrics = ctx.measureText(text);
var xPos = (xaxis.p2c(data[i][0])+offset.left) - metrics.width/2; // place it in the middle of the bar
var yPos = yaxis.p2c(data[i][1]) + offset.top - 5; // place at top of bar,slightly up
ctx.fillText(text,xPos,yPos);
}
