jQuery Flot-显示准确值 [英] jQuery Flot - Display accurate values

问题描述

我注意到jQuery Flot正在舍入结果.但是，当您将鼠标悬停在工具提示中的峰和谷时，我想显示结果的实际十进制值.但不是x或y轴标签，而是图形结果本身.

I notice that jQuery Flot is rounding down the results. But I want to show the actual decimal value for the result when you hover over the peaks and valleys in the tooltip. But not the x or y axis labels, but the graph result itself.

所以我要的不是"44"，而是"44.05".

So instead of "44", I want "44.05".

有什么我可以做的工作吗?我看到的所有内容仅用于轴标签.

Is there anything I can do to make that work? Everything I'm seeing is just for the axis labels.

推荐答案

工具提示应允许您执行此操作-看一下这个小提琴 http://jsfiddle.net/Rnusy/

The tool tip should allow you to do this - have a look at this fiddle http://jsfiddle.net/Rnusy/

 var previousPoint = null;
        $("#placeholder").bind("plothover", function (event, pos, item){
            $("#x").text(pos.x.toFixed(2));
            $("#y").text(pos.y.toFixed(2));
            if (item) {
                if (previousPoint != item.dataIndex){
                    previousPoint = item.dataIndex;

                    $("#tooltip").remove();
                    var x = item.datapoint[0].toFixed(2),
                        y = item.datapoint[1].toFixed(2);

                        showTooltip(item.pageX, item.pageY, y);
                                                    }
                    }
                else {
                    $("#tooltip").remove();
                    previousPoint = null;
                    }

            });
