Flot Charts. Custom color below x-axis value

I have a Flot Bar Chart code.
$(function() {
var barOptions = {
series: {
bars: {
show: true,
barWidth: 0.4,
fill: true,
fillColor: {
colors: [{
opacity: 0.8
}, {
opacity: 0.8
}]
}
}
},
xaxis: {
mode: "categories",
tickLength: 0
},
yaxis: {
min:-200, max: 200, tickSize: 50,
},
colors: ["#1ab394"],
grid: {
color: "#999999",
hoverable: true,
clickable: true,
tickColor: "#D4D4D4",
borderWidth:0
},
legend: {
show: false
},
tooltip: true,
tooltipOpts: {
content: "Cost: %y %"
}
};
var barData = {
label: "bar",
data: [
["First", -100],["Second", 66.67],["Third", -177.77],]
};
$.plot($("#flot-bar-chart"), [barData], barOptions);
});
I want that every bar below 0 would be specific (for example red) color. I have tried to do that with threshold plugin, but it adds additional values. Is there any solution to make it?

The threshold plugin should not add additional values, see this fiddle or the snippet below:
$(function() {
var barOptions = {
series: {
bars: {
show: true,
barWidth: 0.4,
fill: true,
fillColor: {
colors: [{
opacity: 0.8
}, {
opacity: 0.8
}]
},
align: 'center'
}
},
xaxis: {
mode: "categories",
tickLength: 0,
ticks: [
[1, 'First'],
[2, 'Second'],
[3, 'Third']
]
},
yaxis: {
min: -200,
max: 200,
tickSize: 50,
},
colors: ["#1ab394"],
grid: {
color: "#999999",
hoverable: true,
clickable: true,
tickColor: "#D4D4D4",
borderWidth: 0
},
legend: {
show: false
},
tooltip: true,
tooltipOpts: {
content: "Cost: %y %"
}
};
var barData = {
label: "bar",
data: [
[1, -100],
[2, 66.67],
[3, -177.77],
],
threshold: {
below: 0,
color: "rgb(200, 20, 30)"
},
};
$.plot($("#flot-bar-chart"), [barData], barOptions);
});
#flot-bar-chart {
height: 300px;
}

Displaying Labels on Stacked Bar

I would like to display labels on each stacked bar like blue on blue bar, yellow on yellow bar and so on.
Here's my code in JSFiddle:
[1]:http://jsfiddle.net/Sa_2019/n7r57pv7/
Here is my Code :
<div id="placeholder" style="width:600px;height:300px;"></div>
var data = [
{label: 'foo', color:'red', data: [[1,300], [2,300], [3,300], [4,300], [5,300]]},
{label: 'bar', color:'blue', data: [[1,800], [2,600], [3,400], [4,200], [5,0]]},
{label: 'baz', color:'yellow', data: [[1,100], [2,200], [3,300], [4,400], [5,500]]},
];
$.plot($("#placeholder"), data, {
series: {
stack: 1,
bars: {
show: true,
lineWidth: 1,
barWidth: 0.8,
order: 1,
fill: true
},
yaxis : {
min : 0,
tickLength: 0
} ,
xaxis: {
tickLength: 0,
axisLabel: "Date",
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 12,
axisLabelFontFamily: 'Arial',
axisLabelPadding: 3,
color: "#838383",
timeformat: "%b/%y"
}
}
});
Any idea please.
Thank you

You can use dataLabels of Highcharts to solve this . the code will be like :-
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: 'white',
formatter: function () {
// return the value you want to show on labels.. depends on your data ...
console.log(this)
}
}
}
}
something like this you can refer to ...
As of know i have added string "random" to it just change that according to your logic ..

Flot Chart show dates

First of all, excuse me for my english!
I want to show a flot chart with jquery. My code is the following:
charts.chart_simple =
{
// data
data:
{
d1: []
},
// will hold the chart object
plot: null,
// chart options
options:
{
grid:
{
color: "#dedede",
borderWidth: 1,
borderColor: "transparent",
clickable: true,
hoverable: true
},
series: {
lines: {
show: true,
fill: false,
lineWidth: 2,
steps: false
},
points: {
show:true,
radius: 5,
lineWidth: 3,
fill: true,
fillColor: "#000"
}
},
xaxis: {
mode: "time",
tickColor: 'transparent',
tickDecimals: 2,
tickSize: 2
},
yaxis: {
tickSize: 10
},
legend: { position: "nw", noColumns: 2, backgroundColor: null, backgroundOpacity: 0 },
shadowSize: 0,
tooltip: true,
tooltipOpts: {
content: "%s : %y.3",
shifts: {
x: -30,
y: -50
},
defaultTheme: false
}
},
placeholder: "#chart_simple",
// initialize
init: function()
{
// this.options.colors = ["#72af46", "#466baf"];
this.options.colors = [successColor, primaryColor];
this.options.grid.backgroundColor = { colors: ["#fff", "#fff"]};
var that = this;
if (this.plot == null)
{
this.data.d1 = new Array();
var o = 0;
for(var i = 0; i < data.length; i++){
var group = data[i];
for(var e = 0; e < group.length; e++){
var elem = new Array(date, intVal);
this.data.d1[o] = elem;
o++;
}
}
}
this.plot = $.plot(
$(this.placeholder),
[{
label: "Consumo Medio",
data: this.data.d1,
lines: { fill: 0.05 },
points: { fillColor: "#fff" }
}], this.options);
}
};
// uncomment to init on load
charts.chart_simple.init();
The problem is the variable "date". If I put a number it works perfectly.
Variable "date" has this format -> 2014-02-26

You have to use timestamps. See the documentation for explanation and examples.

Thank you very much for your replies.
Finally I found the solution.
var data1 = new Array();
var o = 0;
for(var i = 0; i < data.length; i++){
var group = data[i];
for(var e = 0; e < group.length; e++){
var date = group[e][0];
var year = date.substring(0,4)
var month = date.substring(5,7)
var day = date.substring(8,10)
console.log(year + " | " + month + " | " + day);
var elem = new Array(gd(year, month, day), (group[e][1]/group[e][2]));
data1[o] = elem;
o++;
}
}
var dataset = [
{
label: "Consumo Semana",
data: data1,
color: "#FF0000",
xaxis:2,
points: { fillColor: "#FF0000", show: true },
lines: { show: true }
}
];
var dayOfWeek = ["Dom", "Lun", "Mar", "Mie", "Jue", "Vie", "Sab"];
var options = {
series: {
shadowSize: 5
},
xaxis: {
mode: "time",
tickSize: [1, "month"],
tickLength: 0,
axisLabel: "2012",
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 12,
axisLabelFontFamily: 'Verdana, Arial',
axisLabelPadding: 10
},
yaxis: {
color: "black",
tickDecimals: 2,
axisLabel: "Gold Price in USD/oz",
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 12,
axisLabelFontFamily: 'Verdana, Arial',
axisLabelPadding: 5
},
xaxes: [{
mode: "time",
tickFormatter: function (val, axis) {
return dayOfWeek[new Date(val).getDay()];
},
color: "black",
position: "top",
axisLabel: "Weekday",
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 12,
axisLabelFontFamily: 'Verdana, Arial',
axisLabelPadding: 5
},
{
mode: "time",
timeformat: "%d/%m",
tickSize: [1, "day"],
color: "black",
axisLabel: "Date",
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 12,
axisLabelFontFamily: 'Verdana, Arial',
axisLabelPadding: 10
}],
grid: {
hoverable: true,
borderWidth: 2,
borderColor: "#633200",
backgroundColor: { colors: ["#ffffff", "#EDF5FF"] }
},
colors: ["#FF0000", "#0022FF"]
};
$.plot($("#chart_simple_2"), dataset, options);
function gd(year, month, day) {
return new Date(year, month - 1, day).getTime();
}
The problem was the way that I was introducing date data. With this tutorial I found the answer.

Multi axes flot chart with orderd stacked bars, not stacking neither adjusting bar position

I need help with the following chart, is a multiseries with multiaxes and I need the some bars stacked and others not. I paste the code and here is a demo http://jsfiddle.net/Willem/aAb3E/17/
This are my first axis data (lines not stacked):
var data1 = [
[1375302600000, 33],
[1375300800000, 26]
];
var data2 = [
[1375302600000, 0],
[1375300800000, 12]
];
These are the bars (stacked by user and date(first value)):
var user1_estado1 = [
[1375302600000, 20],
[1375300800000, 40]
];
var user1_estado2 = [
[1375302600000, 10],
[1375300800000, 90]
];
var user1_estado3 = [
[1375302600000, 30],
[1375300800000, 70]
];
var user2_estado1 = [
[1375302600000, 20],
[1375300800000, 40]
];
var user2_estado2 = [
[1375302600000, 10],
[1375300800000, 90]
];
var user2_estado3 = [
[1375302600000, 30],
[1375300800000, 70]
];
I set the dataset options by series; data1 and data2 no bars and stack false; others bars show: true and the order set because I want them to solape by user and datetime.
var dataset = [{
label: "Answer",
data: data1,
bars: {
show: false
},
stack: false,
xaxis: 2
}, {
label: "Not answer",
data: data2,
bars: {
show: false
},
stack: false,
xaxis: 2
}, {
label: "User1_estado1",
data: user1_estado1,
bars: {
show: true,
order:1
},
xaxis: 1,
yaxis: 2,
}, {
label: "User1_estado2",
data: user1_estado2,
bars: {
show: true,
order:1
},
xaxis: 1,
yaxis: 2,
}, {
label: "User1_estado3",
data: user1_estado3,
bars: {
show: true,
order:1
},
xaxis: 1,
yaxis: 2,
}, {
label: "User2_estado1",
data: user2_estado1,
bars: {
show: true,
order:2
},
xaxis: 1,
yaxis: 2,
}, {
label: "User2_estado2",
data: user2_estado2,
bars: {
show: true,
order:2
},
xaxis: 1,
yaxis: 2,
}, {
label: "User2_estado3",
data: user2_estado3,
bars: {
show: true,
order:2
},
xaxis: 1,
yaxis: 2,
}];
Plot them, setting barwith (each half time) this I don´t know how to adjust :(, and the diferent axes, xaxes now by time but I need the xaxe1 to show each user.
var plot = $.plot(
$("#placeholder"), dataset, {
series: {
bars: {
barWidth: 60*30*1000,
align: "center",
fill: true,
},
//pointLabels:{show:true, stackedValue: true},
},
grid: {
hoverable: true,
clickable: true,
tickColor: "#f9f9f9",
borderWidth: 2,
mouseActiveRadius: 10
},
xaxes: [{
show: true,
mode: "time",
timeformat: "%H:%M",
tickSize: [0.5, "hour"],
axisLabel: "Usuario",
axisLabelFontSizePixels: 3,
axisLabelPadding: 5
}, {
show: true,
mode: "time",
timeformat: "%H:%M",
tickSize: [0.5, "hour"],
axisLabel: "Usuarios ocupados",
axisLabelFontSizePixels: 3,
axisLabelPadding: 5
}],
yaxes: {
color: "black",
axisLabel: "Usuarios ocupados",
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 8,
axisLabelFontFamily: 'Verdana, Arial',
axisLabelPadding: 5,
tickDecimals: 0
}
});
Here I add some interactive to the graph showing some tooltips.
var previousPoint = null,
previousLabel = null;
$("#placeholder").bind("plothover", function (event, pos, item) {
if (item) {
if ((previousLabel != item.series.label) || (previousPoint != item.dataIndex)) {
previousPoint = item.dataIndex;
previousLabel = item.series.label;
$("#tooltip").remove();
var x = new Date(item.datapoint[0]);
var y = item.datapoint[1];
var color = item.series.color;
showTooltip(item.pageX, item.pageY, color,
"<strong>" + item.series.label + "</strong><br>" + (x.getMonth() + 1) + "/" + x.getDate() +
" : <strong>" + y + "</strong> llamadas");
}
} else {
$("#tooltip").remove();
previousPoint = null;
}
});
function showTooltip(x, y, color, contents) {
$('<div id="tooltip">' + contents + '</div>').css({
position: 'absolute',
display: 'none',
top: y - 40,
left: x - 30,
border: '2px solid ' + color,
padding: '3px',
'font-size': '9px',
'border-radius': '5px',
'background-color': '#fff',
'font-family': 'Verdana, Arial, Helvetica, Tahoma, sans-serif',
opacity: 0.9
}).appendTo("body").fadeIn(200);
}
My problem is to align the bars per user and time (better being stacked) and to not stack the two lines. I also like to show in the axis1 the ticks by user (not the time).
You can see it here http://jsfiddle.net/Willem/aAb3E/17/
Please need some help for driving this :).
Thank you very much!

To prevent the lines from stacking, get rid of some options that you don't really need:
var dataset = [{
label: "Answer",
data: data1,
xaxis: 2
}, {
label: "Not answer",
data: data2,
xaxis: 2
}, ...
To be honest I'm not entirely sure why 'false' caused them to stack; that seems like a bug, but in any case simply removing the option solves the problem, since the default is not to stack.
I'm not clear on what you mean by 'align the bars per user and time'; can you explain?

jqplot won't give me padding on my inner grid

We have a graph that looks like:
Very nice. Well, except for the first and last bars being split in half!
I know why it's doing it, but I don't know how to fix it. I've tried gridPadding, barPad, and Pad. Probably others. For whatever reason, I cannot seem to get them to push without prepending and appending some blank dummy data. Which makes an extra two confusing entries along the bottom, which is definitely not acceptable.
The code is as follows.
var f = [[0,1.29],[1,1.29],[2,1.48],[3,1.48],[4,1.48],[5,1.48],[6,1.48],[7,1.48]];
var v = [[0,0.71],[1,0.71],[2,0.8],[3,0.8],[4,0.8],[5,0.8],[6,0.8],[7,0.8]];
var p = [[0,-0.26],[1,-0.26],[2,0.67],[3,0.67],[4,0.67],[5,0.67],[6,0.67],[7,0.67]];
// [x position, y height]
var x_line = [[0,1],[1,21],[2,33],[3,39],[4,21],[5,21],[6,21],[7,21]];
var rank_ticks = [0,1,2,3,4,5,6,7];
