jQuery Flot - Display accurate values


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.

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

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


Solution

  • 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;
                        }
    
                });
