I am working with a sample here:
var startDate = new Date(Date.UTC(2016, 6, 28, 0, 0, 0, 0));
var endDate = new Date(Date.UTC(2016, 6, 28, 0, 0, 0, 0));
endDate.setHours(startDate.getHours() + 9);
var dataSet = [{"data":[[1469664000000,0]],"color":"#FF0700"},
{"data":[[1469667600000,0]],"color":"#FF0700"},
{"data":[[1469671200000,0]],"color":"#FF0700"},
{"data":[[1469674800000,0]],"color":"#FF0700"},
{"data":[[1469678400000,0]],"color":"#FF0700"},
{"data":[[1469682000000,0]],"color":"#FF0700"},
{"data":[[1469685600000,0]],"color":"#FF0700"},
{"data":[[1469689200000,0]],"color":"#FF7400"},
{"data":[[1469692800000,0]],"color":"#006900"}];
var options = {
series: {
stack: true,
bars: {
show: true
}
},
bars: {
lineWidth: 0,
align: "center",
barWidth: 1,
horizontal: true,
fill: 1,
},
yaxis: {
axisLabel: "MachineName",
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 12,
axisLabelFontFamily: 'Verdana, Arial',
axisLabelPadding: 3,
ticks: []
},
xaxis: {
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 12,
axisLabelFontFamily: 'Verdana, Arial',
axisLabelPadding: 3,
//ticks: [[0, "1:00"], [1, "2:00"], [2, "3:00"], [3, "4:00"], [4, "5:00"], [5, "6:00"], [6, "7:00"], [7, "8:00"], [8, "9:00"]],
//labelWidth: 10,
//tickLength: 10,
//tickFormatter: formatXAxis,
//tickSize: 360000,
//minTickSize: 1,
//min: 0,
//max: 10
//mode: "time",
//timeformat: "%H:%M",
//minTickSize: [1, "hour"],
////color: "black",
//min: startDate.getTime(),
//max: endDate.getTime()
}
};
$.plot($("#machineStatus"), dataset, options);
I end up with a graph where the xaxis labels are not anything like they should be. See below
The design is an hourly status of a machine (red = not running, green = running, etc.) So the intent was to have the last 9 hours of runtime showing and put x axis labels for the top of the hour (1:00, 2:00, etc.).
Since this is a horizontal stack of multiple data sets, this appears to really confuse the xaxis tick calculation. I tried setting the min/max to equal the start and end times of the dataset, but I would get no graph.
I stopped using the "time" mode, hoping I could use the ticks array and force a set of ticks and labels, but that doesn't work. I tried the tickFormatter to force calculating the ticks, but that didn't work either.
You can see all the things I've tried on the xaxis and have commented out. I actually don't want the ticks to have any relationship to the actual data. I am testing this graph at the hour and minute level, so theoretically my data sets are either 9 or 540 bits of granular information. I still want the xaxis ticks to stay at a fixed set of 9 values spread evenly. Any ideas how I can do that?
FYI, I apologize for no jsfiddle. I've never been able to get one to work.
Update. Selected answer works! Here's a screenshot of a 540 datapoint to the minute level. The dataset is too big to post. Thanks again Raidri
I got it to work with time mode and a vertical bar chart:
Relevant options:
series: {
stack: true,
bars: {
lineWidth: 0,
align: "left",
barWidth: 3600000,
//horizontal: true,
fill: 1,
show: true,
}
},
...
xaxis: {
min: startDate.valueOf(),
max: endDate.valueOf(),
mode: "time",
timeformat: "%H:%M",
...
Also the values for your datapoints are changed to 1 so the bars here have a height of one.
If you change it to minute values, you have to change the barWidth option accordingly.
See this fiddle for the full example.

I have a chart which now looks like this:
xAxes: [{
scaleLabel: {
display: true,
labelString: 'log(Re)',
},
type: 'linear',
ticks: {
suggestedMax: 10000,
maxTicksLimit: 10,
},
afterBuildTicks: function(scale) {
scale.ticks = [1, 10, 100, 1000, 10000]
}
}]
Need to create ticks [1, 10, 100, 1000, 10000], (like in first image), but with equal spacing between this ticks, like here:
Dmytro, I think your basic problem is that the tick marks you want are powers of 10, not plain numbers. Set your tick marks to be 0, 1, 2, 3, 4 and they will be shown at even intervals. Then label them 1, 10, 100, etc. (1=10^0, 10=10^1, 100=10^2, etc). You may have to restructure your data set a bit to get the correct tick mark values in. But that should give you the effect you are after.
I would like to have my chartist charts on my website with no padding from left or right. I am using chartPadding: 0 as advised on several websites, but that did not really help. There is still too much air from the left or right border.
Here is jsFiddle. Help would be great!
var chart = Chartist.Bar('.ct-chart', {
labels: ['1.58', '2.58', '4.58', '5.2', '3.1'],
series: [
[12, 9, 7, 8, 5],
[2, 1, 3.5, 7, 3],
[1, 3, 4, 5, 6]
]
}, {
showPoint: true,
showLine: true,
fullWidth: true,
showLabel: false,
axisX: {
showGrid: false,
showLabel: true,
offset: 50
},
axisY: {
showGrid: false,
showLabel: false,
offset: 0
},
chartPadding: 0,
low: 0
});
// Listening for draw events that get emitted by the Chartist chart
chart.on('draw', function(data) {
// If the draw event was triggered from drawing a point on the line chart
if(data.type === 'label' && data.axis === 'x') {
// We just offset the label X position to be in the middle between the current and next axis grid
data.element.attr({
dx: data.x + data.space / 2
});
}
});
<link href="https://rawgit.com/gionkunz/chartist-js/master/dist/chartist.min.css" rel="stylesheet"/>
<script src="https://rawgit.com/gionkunz/chartist-js/master/dist/chartist.min.js"></script>
<div class="ct-chart"></div>
You can put negative values to the chartPadding property, but that would not give you the effect you are aiming for.
As you render the chart in a normal div the default width value is set to 100%. What you can do as a work around is to restrict the width, so there is less space for the svg. This will affect the padding on the left/right.
Here the updated fiddle - https://jsfiddle.net/zeq3da7p/3/
I am currently working on some flot graphs that display single and multiple sets of data relating to time. Below is an example image of a single set of data on the graph.
Single data set
A date time picker allows a user to compare two time ranges where the second data set draws over the initial set. The issue I'm having is that when the second dataset is drawn over the first the whole graph shifts upwards revealing a large white space where the hidden ticks should be, see the example image below.
Multiple dataset
As you can see the data sets are different time ranges therefore can't be on the same axis as they are a comparison. Here's my options for the axes.
xaxes: [{
tickColor: "#fff",
mode: "time",
timeformat: timeFormat,
minTickSize: tickSize,
font: {
style: "normal",
color: "#666666"
},
axisLabel: xLabel,
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 11,
axisLabelColour: "#666666",
axisLabelFontFamily: 'Open Sans',
axisLabelPadding: 20
},
{
ticks: [],
mode: "time",
timeFormat: timeFormat
}],
applying the option show: false on the second xaxis removes the shifting completely however because it is false my tooltips for the graph points are also removed.
I m using flot.time, flot.tooltip and flot.axislabels if needed to know.
This is my first question so any feedback would be great :)
My example on JSFiddle.
It all comes down to 2 main changes. Assign your compare graph data to second x-axis:
var dataSet = [{
data: [
[1467669600000, 12],
[1467709200000, 14]
],
label: 'data1',
xaxis: 1
}, {
data: [
[1467583200000, 15],
[1467622800000, 13],
[1467662400000, 16]
],
label: 'data2',
xaxis: 2
}];
For aesthetics, you should hide the second x-axis, so it won't mirror the same hours (set show: false)
{
"show": false,
"mode": "time",
"timeformat": "%H:%M",
"tickSize": [2, "hour"],
"min": 1467583200000,
"max": 1467666000000,
"timezone": "browser"
}
I am trying to graph a month out in flot (per day) or possibly every other day, have a tick.
To get my time values, i am doing this:
$date = strtotime($rowData[0]); // 2013-01-01
$myData = json_encode(array($date*1000, 1234));
// I Then echo it out as an array into the javascript var.
For some reason, i can change the line: minTickSize: [1, day] to 2 (label every other tick i think) and nothing will change. Also, the time values are not showing up as well? What am i doing wrong?
Here is a JSFIDDLE
Here is an update with every two days...is there a rendering issue? Also, why is Oct 10, the only date shown? : JSFIDDLE UPDATE
Here is what i have as far as the javascript goes:
var myData = [[1380603600000,0],[1380690000000,0],[1380776400000,0],[1380862800000,0],[1380949200000,0],[1381035600000,0],[1381122000000,0],[1381208400000,0],[1381294800000,0],[1381381200000,0],[1381467600000,0],[1381554000000,0],[1381640400000,1],[1381726800000,0],[1381813200000,0],[1381899600000,0],[1381986000000,0],[1382072400000,0],[1382158800000,0],[1382245200000,0],[1382331600000,0],[1382418000000,0],[1382504400000,0],[1382590800000,0],[1382677200000,0],[1382763600000,0],[1382850000000,0],[1382936400000,0],[1383022800000,0],[1383109200000,0],[1383195600000,0]];
var plot = $.plot($(".subsChart"),
[ { data: myData, label: "myData"} ], {
series: {
lines: { show: true,
lineWidth: 2,
fill: true, fillColor: { colors: [ { opacity: 0.5 }, { opacity: 0.2 } ] }
},
points: { show: true,
lineWidth: 2
},
grow: { active: true,
steps: 30
},
shadowSize: 0
},
grid: { hoverable: true,
clickable: true,
tickColor: "#DDD",
borderWidth: 1,
borderColor: "#DDD"
},
colors: ["#FF0000"],
xaxis: {mode: "time", timeformat: "%b %m", ticks: myData, minTickSize: [5, "day"]},
yaxis: {ticks:3, tickDecimals: 0},
tooltip: true,
});
UPDATE
When i remove the ticks: myData option, the labels do show up, but all of them are on the same date? Also, none of the points even land on the dates.
As #Smokie suggested, you need to remove the ticks option. When you provide ticks, Flot skips any tick generation that it would normally do and uses what you provided instead, which in this case is invalid.
Once you do that, you'll notice that you have labels, but they all show Oct. 10. That's because your date format is %b (short month name) %m (month number). I'd guess that what you actually want is %b %d.
Note that you probably won't get a tick for every day because, depending on the size of your window, they wouldn't all fit. That's why minTickSize is a minimum rather than an exact value; Flot will ensure that at least one day (or however many you specify) separates the ticks, but may choose to spread them out further to ensure that they all fit.
I am using Flot to draw some bar charts. How do I configure the zoom so that when a user zooms out, the chart will look like the one at the top and not like the one at the bottom? In other words, I don't want the user to continue zooming out when all of the data for the chart is shown. I also want to restrict the chart from displaying anything below 0 on the X axis. See my code and pictures of the charts below:
<#macro barChart2 var formatFunction ticks="" optionLegend="{ show: false }">
var options = {
yaxis: {
tickFormatter: ${formatFunction}
},
series: {
stack: 0,
bars: {
show: true,
barWidth: 0.9,
align: "center"
}
},
grid : {
hoverable: true
},
xaxis: {
<#if "${ticks}" != "">
ticks: ${ticks}
</#if>
mode: "time",
timeformat: "%b %d, %H:%M %P"
},
pan : {
interactive: true
},
legend: ${optionLegend}
};
var plot${var} = $.plot($("#chart${var}"), data, options);
$("#zoomIn${var}").click(function(e) {
e.preventDefault();
plot${var}.zoom();
});
$("#zoomOut${var}").click(function(e) {
e.preventDefault();
plot${var}.zoomOut();
});
</#macro>
I suggest you take a look at the zoomRange and panRange parameters that you can set with the navigation plugin. You specify those for the axes like:
xaxis: { zoomRange: [0.1, 10], panRange: [-10, 10] },
yaxis: { zoomRange: [0.1, 10], panRange: [-10, 10] }
where zoomRange sets the limit for zooming. In this case, the difference between the min and max will never go below 0.1, and it will never exceed 10. panRange tells the content to stay in a certain range, so in this case, neither axis will pan below -10 or above 10.
I'm not sure how you do this with time series data, but try with javascript timestamps to begin with.
