i want to use bar chart istead of sparkline on highcharts in this example

please take a look at this jsfiddle first
jsfiddle example of sparkline
Highcharts.SparkLine = function (a, b, c) {
var hasRenderToArg = typeof a === 'string' || a.nodeName,
options = arguments[hasRenderToArg ? 1 : 0],
defaultOptions = {
chart: {
renderTo: (options.chart && options.chart.renderTo) || this,
backgroundColor: null,
borderWidth: 0,
type: 'area',
margin: [2, 0, 2, 0],
width: 120,
height: 20,
style: {
overflow: 'visible'
},
// small optimalization, saves 1-2 ms each sparkline
skipClone: true
},
title: {
text: ''
},
credits: {
enabled: false
},
xAxis: {
labels: {
enabled: false
},
title: {
text: null
},
startOnTick: false,
endOnTick: false,
tickPositions: []
},
yAxis: {
endOnTick: false,
startOnTick: false,
labels: {
enabled: false
},
title: {
text: null
},
tickPositions: [0]
},
legend: {
enabled: false
},
tooltip: {
hideDelay: 0,
outside: true,
shared: true
},
plotOptions: {
series: {
animation: false,
lineWidth: 1,
shadow: false,
states: {
hover: {
lineWidth: 1
}
},
marker: {
radius: 1,
states: {
hover: {
radius: 2
}
}
},
fillOpacity: 0.25
},
column: {
negativeColor: '#910000',
borderColor: 'silver'
}
}
};
options = Highcharts.merge(defaultOptions, options);
return hasRenderToArg ?
new Highcharts.Chart(a, options, c) :
new Highcharts.Chart(options, b);
};
i try to use the concept of having those sparkline between table tags and achieve a chart with more than 2 column on left and right , however instead of sparkline i need bar chart like a picture below
please help me on this problem ...
Update :
thanks to ppotaczek and his suggestion on changing to bar type i had another problem on the way
updated jsfiddle with bar type
well now i don't know how to make every row to adopt xrow size of 115 . at this moment all bar chart draw the entire cell but 20 from 115 must have different view via 71 from 115 ...
any suggestion to how to put 0 to 115 on the top of the table and adjust the bar charts with that ?

You need to change chart.type to 'bar' and adapt data in the HTML table.
chart: {
type: 'bar',
...
}

Adding Custom Point on the X axis- Kendo UI

I have the following project and only missing piece that I could not able to figure out that to add 0 on the X axis. The interval is 2000, therefore it is skipping 0 in the middle of X axis, which is start point.
xAxis: {
min: -5000
, axisCrossingValue: [-5000, 0],
labels: {
template: kendo.template($("#labelTemplate").html())
},
}
, yAxis: {
reverse: true
, labels: {
format: "{0}"
}
}
http://jsfiddle.net/3yhbyy2g/37/

Add majorUnit:1000 to the xAxis
xAxis: {
majorUnit:1000, //<-add here
min: -5000
, axisCrossingValue: [-5000, 0],
labels: {
template: kendo.template($("#labelTemplate").html())
},
}
, yAxis: {
reverse: true
, labels: {
format: "{0}"
}
}

Flot Graph not plotting data

I a trying to plot some information using a flot graph but I can not get the values to appear on the graph. This code was part of a demo file included in a template and so i have modified it to plot the data rather than using a randomise for the values, i am getting no errors but the chart isn't working and was hoping somebody could point me in the right direction.
My code is here:
init: function()
{
// apply styling
charts.utility.applyStyle(this);
this.plot = $.plot(
$("#chart_simple"),
[{
label: "Jobs",
data: this.data.d1,
lines: {fillColor: "#dd3333"},
points: {fillColor: "#dd3333"}
},
{
label: "Resumes",
data: this.data.d2,
lines: {fillColor: "#282b30"},
points: {fillColor: "#282b30"}
}], this.options);
}
},
// lines chart with fill & without points
chart_lines_fill_nopoints:
{
// chart data
data:
{
d1: [[1,100], [2,150], [3,100]],
d2: [[1,100], [2,150], [3,100]]
},
// will hold the chart object
plot: null,
// chart options
options:
{
grid: {
show: true,
aboveData: true,
color: "#3f3f3f",
labelMargin: 5,
axisMargin: 0,
borderWidth: 0,
borderColor:null,
minBorderMargin: 5 ,
clickable: true,
hoverable: true,
autoHighlight: true,
mouseActiveRadius: 20,
backgroundColor : { }
},
series: {
grow: {active:false},
lines: {
show: true,
fill: true,
lineWidth: 2,
steps: false
},
points: {show:false}
},
legend: { position: "nw" },
yaxis: { min: 0 },
xaxis: {ticks:11, tickDecimals: 0},
colors: [],
shadowSize:1,
tooltip: true,
tooltipOpts: {
content: "%s : %y.0",
shifts: {
x: -30,
y: -50
},
defaultTheme: false
}
},

So, digging a bit, I see you are using javascript from here. Looking at a working example here, you've broken their code in the following ways:
1.) You no longer seem to have a parent charts object, so
charts.utility.applyStyle(this);
isn't going to work.
2.) The init function is part of the chart_lines_fill_nopoints object, in your cut/paste code it isn't anymore.
3.) In your sample code you never actually call the init function to draw the plot.
4.) In the options backgroundColor : { } is invalid for flot (maybe this is part of the missing charts.utility.applyStyle).
Taking all this into account here's a fiddle which makes this code work.
Generating flot plots with the above code feels unnecessarily convoluted. Perhaps it makes sense when using these templates, but if you just using this as an example of how to call flot it's not very straightforward.
Also, please next time you post a question, include all relevant information (like where you found this code and how you changed it). Taken out of context this code makes little sense.

This code is working
//Defining data for the chart
var data=
{
d1: [[1,100], [2,150], [3,100]],
d2: [[1,100], [2,150], [3,100]]
};
//Defining options for the chart
var options=
{
grid: {
show: true,
aboveData: true,
color: "#3f3f3f",
labelMargin: 5,
axisMargin: 0,
borderWidth: 0,
borderColor:null,
minBorderMargin: 5 ,
clickable: true,
hoverable: true,
autoHighlight: true,
mouseActiveRadius: 20,
backgroundColor : { }
},
series: {
grow: {active:false},
lines: {
show: true,
fill: true,
lineWidth: 2,
steps: false
},
points: {show:false}
},
legend: { position: "nw" },
yaxis: { min: 0 },
xaxis: {ticks:11, tickDecimals: 0},
colors: [],
shadowSize:1,
tooltip: true,
tooltipOpts: {
content: "%s : %y.0",
shifts: {
x: -30,
y: -50
},
defaultTheme: false
}};
// shorthand for document.ready
$(function(){
this.plot = $.plot(
$("#chart_simple"),
[{
label: "Jobs",
data: data.d1,
lines: {fillColor: "#dd3333"},
points: {fillColor: "#dd3333"}
},
{
label: "Resumes",
data: data.d2,
lines: {fillColor: "#282b30"},
points: {fillColor: "#282b30"}
}], this.options);
});

Flot chart multiple axes are not configured properly

I am expecting pretty weird problem with flot v.0.7. I have multiple axes, configured like that:
var plotData = [
{ data: data1 },
{ data: data2, yaxis: 2 }];
var options = {
selection: { mode: "x" },
xaxis: { mode: "time" },
yaxis: [
{ min: 0 },
{
min: 0,
position: "right",
zoomRange: false,
alignTicksWithAxis: 1,
tickFormatter: formatter,
}
],
grid: { markings: weekendAreas },
zoom: { interactive: true },
grid: {
clickable: true,
hoverable: true,
borderWidth: 1,
},
legend: { show: false },
};
var plot = $jq.plot(container, plotData, options);
But what I get is that both Y series are located on the right (not only second Y series). There is no formatter for my second series tick. Y values can be less then zero, if zooming. If I don't use array type for yaxis and define it as it would only be one series, then everything works fine. What am I doing wrong?

Instead of yaxis: [ ... ], use yaxes: [ ... ].
See the section of the docs entitled Multiple Axes for more info.

Flot Date Issue

i'm trying to display a date field in flot:
Data:
var data = [
[parseInt(1309150800.0)*1000, 220],
[parseInt(1309064400.0)*1000, 230],
];
Flot creation:
$.plot($("#graph"), [ data ], {
grid: {
hoverable: true
},
xaxis: {
mode: "time",
timeformat: "%d.%m.%y"
},
yaxis: {
mode: "number",
tickSize: 2
},
series: {
lines: { show: true },
points: { show: true }
}
});
According to this site http://tools.semsym.com/index.php?tool=timestamp&timestamp=1309150800 the timestamp is Jun 26, 2011 10:00:00 PM.
But the graph looks like: http://i.stack.imgur.com/NUayx.png
The dots are a bit off. The first one should be at 26, but is at 25,5. I played a bit with timestamp formatting but wasn't able to get it to the specific point.
What am i missing?
Also it shows "26.06.2011" about 6 times. What config is needed to keep it at 1?

Make sure you set a minTickSize. Here is an example at http://jsfiddle.net/hAXHq/ where I have set minTickSize to 1 day and set the min/max values explicitly. You should be able to set your own min/max programmatically depending on your data.
Here is the code:
var data = [
[parseInt(1309150800.0)*1000, 220],
[parseInt(1309064400.0)*1000, 230]
];
$.plot($("#placeholder"), [ data ], {
grid: {
hoverable: true
},
xaxis: {
mode: "time",
timeformat: "%d.%m.%y",
minTickSize: [1,"day"],
min: (new Date(2011,5,25)).getTime(),
max: (new Date(2011, 5, 28)).getTime()
},
yaxis: {
mode: "number",
tickSize: 2
},
series: {
lines: { show: true },
points: { show: true }
}
});
