I am using flotchart JS for showing bar graphs. However, I can't seemed to fix the spacing between bars.
I have enabled panning already. However, sets the width of the bar according to the placeholder. How can set each bar's spacing according to its label?
this is my code:
$.plot("#graph", [ data ], {
series: {
bars: {
show: true,
barWidth: 0.6,
align: "center"
}
},
xaxis: {
mode: "categories",
showTicks: false,
gridLines: false,
panRange: [0,null],
},
yaxis: {
panRange: [0, null],
plotPan: false //pan axis is allowed for plot pan
},
pan: {
interactive: true,
mode: "smart",
active: true
}
});
An alternative solution to your problem could be to rotate the tick labels for example by using the tickrotor plugin:
xaxis: {
mode: "categories",
showTicks: false,
gridLines: false,
panRange: [0,null],
rotateTicks: 90
},
You may need to increase the height of the chart since the labels now take up more space. See this fiddle for a full example.
You can achieve this by limiting the number of bars shown at once by giving a max property for the xaxis:
xaxis: {
mode: "categories",
showTicks: false,
gridLines: false,
panRange: [0,null],
max: 7, // set according to your needs, maybe dynamic depending on chart width
min: 0
},
You then have to use panning to see the other bars. See this fiddle for an example.
I am using Highcharts v6.0.7.
Objective:
I need to center align column bars “on” x-axis tickmarks.
Configuration:
Highcharts column chart
X-axis is datetime and non-categorized.
I am using pointPlacement with a numeric value in order to center align the column bars of my chart over x-axis tickmarks.
Issue:
Yesterday, a certain numeric value for pointPlacement centered the column bars “on” tickmarks. However, today, all configuration remaining same, the column bars are at an offset from the x-axis tickmarks.
Questions:
Is this a bug with Highcharts or should I need more configuration along with pointPlacement to center the column bars. I referred to this documentation -- https://api.highcharts.com/highcharts/series.column.pointPlacement
For non-categorized x-axes, is there an alternative property to center the column bars on axis tickmarks?
I see that in my chart, pointPlacement values of “on” and “between” do not work as expected. Also a value of 0 does not center the column bar “on” the axis tickmarks (the documentation states it should)
Code
this.chart = new Chart({
chart: {
type: 'column',
},
title: {
text: this.title
},
xAxis: {
type: this.xType,
startOnTick: true,
min: moment(this.pointStart).add(1, 'days').unix() * 1000,
tickInterval: this.xTickInterval,
labels : {
align: 'center'
}
},
yAxis: {
...
},
tooltip : {
...
},
credits: {
...
},
plotOptions: {
column: {
pointPlacement: 0.4
},
series: {
pointStart: this.pointStart ? moment(this.pointStart).unix() * 1000 : 0,
pointInterval: this.pointInterval,
showInLegend: false
}
},
series: [{
data: [], //show empty grid initially
}]
});
I'm creating a HighStock column bar chart. I have enabled the scrollbar using scrollbar: enabled. The scrollbar works fine for smaller datasets, but this dataset has a lot of categories(I've only included half as many as I need). For some reason, after a certain number, the rects for the bar chart won't properly show(or show wrong values) and the xAxis labels display as numbers rather than their actual names. Also, I'm trying to add IDs to each of the bars to add click events, but it only adds IDs to bars that are properly rendered initially. I have also noticed that I can properly add IDs even with a scrollbar to smaller data sets because all of the rect elements are properly rendered. Is there any way to make this scrollbar work for larger datasets?
You'll see what the problem described above looks like in this link:

});
It happens because the number of points in series is bigger than the default value of the cropThreshold property (more about below, in the API Reference section). As a solution, set the property with the bigger value.

I'm trying to move the x-axis labels so that they appear along the line x=0. The scales are constantly changing, so I don't want to set the location using pixels, as y=0 may not be in the same location for each plot.
I tried looking up this question on this site and someone recommended using "crossing:0," as shown below, but that doesn't work.
xAxis: {
min: -20,
max: 20,
tickInterval: 1,
gridLineWidth: 1,
endOnTick: false,
crossing:0,
title: {
text: 'some value',
},
If someone could help me with this positioning, I would appreciate it.
Here's my JsFiddle: http://jsfiddle.net/z7eyv/35/
crossing is not an out-of-the-box feature of Highcharts.
Based on what I could find, it seems what you want is the "Crossing-Specific-Value" Highcharts plugin, which is located here: http://www.highcharts.com/plugin-registry/single/6/Crossing-Specific-Values
Update (July 5, 2016): To address the comments about your fiddle, you need to explicitly add the "Crossing-Specific-Value" plugin after your bring in the Highcharts library (see the third line below):
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<script src="https://rawgithub.com/highslide-software/crossing-specific-value/master/crossing-specific-value.js"></script>
Now, adding the crossing variable to your x-axis will show the labels as in the demo.
I made a few tweaks to your fiddle (see http://jsfiddle.net/brightmatrix/z7eyv/38/) to better suit what you're asking.
1) Using the demo as the default, it seems that the plugin puts your labels above the axis line. I've seen instances where the labels are better ready below the line so I did the following:
xAxis: {
crossing: 0,
opposite: true,
min: -20,
max: 20,
tickInterval: 1,
gridLineWidth: 1,
endOnTick: false,
title: { text: '' },
labels: { y: 15 } // pushes the labels down below the crossing line
},
2) I then adjusted the plot line for the y-axis as follows:
yAxis: {
min: -20,
max: 20,
tickInterval: 1,
endOnTick: false,
title: { text: 'some value' },
plotLines: [{
value: 0.1,
width: 1,
color: 'black',
zIndex: 10 }] // moves the plot line above the axis gridline
},
The zIndex value of 10 means the line will show up on top of the normal gridline. Here's how this looks:
Please let me know if this better answers your question.
I'm trying to plot some data on a webpage. I have 4+ series with a common Xaxis but the scaling on the Yaxis should be unique for each series.
Something like the below picture (you can see multiple scales on both Y and Y2 axis)
I've been testing out jqplot it supports a Y and Y2 axis but I cannot see a way to have more that one scale on each axis is this possible?
If not is there another package I can use that can do this?
I have discovered JQplot supports more than two YAxis but each Axis after the first axis will be displayed on the right hand side of the plot I've found no simple way to modify this behaviour. The below picture is a plot I was able to create using 4 yaxis scales
.
Something like the below Javascript in the plot statement will do it.
axes: {
xaxis: {
show: true,
renderer: $.jqplot.LinearAxisRenderer,
drawMajorGridlines: true,
min: 0,
max: 21,
numberTicks: 7,
},
yaxis: {
show: true,
renderer: $.jqplot.LinearAxisRenderer,
},
y2axis: {
show: true,
renderer: $.jqplot.LinearAxisRenderer,
},
y3axis: {
show: true,
renderer: $.jqplot.LinearAxisRenderer,
},
y4axis: {
show: true,
renderer: $.jqplot.LinearAxisRenderer,
},
},
