Making the jqPlot area smaller - jqplot

Hi I have got a pie chart which is generated using jqPlot. But the jqPlot area is covering the whole width of the page. I want to show that only at the left half of the page. Can any on please provide me a little help to do this.
My code is given below-
var plot2 = jQuery.jqplot ('month_record', [data],
{
title: "Records saved per month in the previous year",
seriesDefaults: {
// Make this a pie chart.
renderer: jQuery.jqplot.PieRenderer,
rendererOptions: {
// Put data labels on the pie slices.
showDataLabels: true,
startAngle:-90,
dataLabels: monthRecord,
dataLabelFormatString:'%d',
}
},
legend: { show: true, location: 'e' }
}
);

jqPlot uses the height/width of the container <div> to set the plot dimensions.
<div id="chart" style="width: 400px; height: 260px;" class="jqplot-target">
<!-- plot will render here with the above dimensions -->
</div>

c3.js - How to manually trigger the hover of a donut arc?

I'm using c3.js and have a donut chart that has custom text inside the donut as you hover over each category. I got that all working great.
I have some custom elements relating to the chart but are detached from the chart completely... if user hovers on those custom elements, i need to trigger a hover over a specific donut arc so the "onmouseover" triggers and the middle of donut gets updated as well.
var chart = c3.generate({
data: {
columns: [
['data1', 30],
['data2', 120],
],
type: 'donut',
onmouseover: (d) => {
// does stuff to middle of donut not included here
console.log("onmouseover", d);
}
},
donut: {
title: "custom data here"
},
});
// i want to highlight and run onmouseover for specific chart arc
$('.custom-bars .bar').hover(
function() {
var id = $(this).data('id');
console.log('trigger ' + id + ' arc hover state');
}, function() {
// remove hover
}
);
.custom-bars .bar {
background: #ccc;
margin-bottom: 10px;
padding: 10px;
display: inline-block;
cursor: pointer;
}
<div class="custom-bars">
<div class="bar bar1" data-id="data1">data1 related stuff</div>
<div class="bar bar2" data-id="data2">data2 related stuff</div>
</div>
<div id="chart" style="width:100%; height: 350px;"></div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/c3/0.3.0/c3.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.4.12/d3.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
so when someone hovers over .bar1 I want to manually trigger data1 column on the chart so it highlights that arc and runs the "onmouseover" callback which updates the middle of the donut and everything else I need to do. The handling of generating chart and custom-bars will be in separate class methods.
https://jsfiddle.net/pelluche/2adtw71o/30/
Thanks to Ruben I think I figured out how to manually trigger a donut arc. I updated my fiddle. chart.focus() trigger the highlight but it doesn't run the onmouseover, so to grab it's values you can use chart.data.shown(). If someone knows a way to trigger the onmouseover of that arc please let me know.
$('.custom-bars .bar').hover(
function() {
var id = $(this).data('id');
var arcData = chart.data.shown(id);
chart.focus(id);
console.log(arcData);
}, function() {
chart.revert();
}
);

Rickshaw.js gradient color on area chart?

I am trying to create an area chart with gradient, like shown in the image.
I don't see where can I specify the gradient. I have created a CSS class and tried to add it to the chart series
var graph_lc2 = new Rickshaw.Graph({
element: document.getElementById("linechart2"),
height: 100,
renderer: 'area',
stroke: true,
preserve: true,
series: [{
className: 'my-gradient',
data: seriesData[1],
name: 'Demo'
}]
});
Any ideas?

C3 / D3 bar chart with horizontal scroll

I'm working on creating a c3 bar chart where each bar represents the # of people who joined a program in the given week. Data is just an array of objects with [{week, # of people}, {week, # of people}, etc.]
Ideally, I want the latest 6 weeks to show in the chart, but I want to be able to scroll horizontally to see past weeks.
I saw one answer to this (D3.js scrolling bar chart), but in this case, the axis did not stay visible when scrolling - which I would like to do.
Any help would be much appreciated.
c3.js allows you to make a "Sub Chart", which in essence is similar to a stock chart such as those you would see on Google Finance.
I suspect you would be better off letting the Sub Chart be your mechanism for scrolling than trying to implement a scrollbar from css.
One of the nice features of the c3 Sub Chart is how it allows to set the 'default extent' for the Sub Chart. What you could do is use the extent to default to a limited number of weeks, and from there, the user can manipulate the Sub Chart slider/brush as they see fit. Here is a simple implementation/dummy example:
axis.x.extent
http://c3js.org/reference.html
...Set default extent for subchart and zoom.

Remove borders around swatches on legend for Pie graph (jqplot)

How do I remove the border around the swatches in the legend of a JQPlot graph? Below is my code. There is a border around the swatches, but the border is bigger than the square and I would prefer to remove it. Then this might be a second question (and I will remove if someone just answers one or asks me to): I have 4 sets of the raw data for every slice. How to I show more of this data in the legend (eg: the name and the amount and percentage)
Below is the code I have:
var budgetGraph = [["GROCERIES",4194.02,57.95302704323518,10],["BUSINESS MISCELLANEOUS",918.19,12.68756226742555,102],["HEALTHCARE/MEDICAL",729.65,10.082313909351063,11],["HOBBIES/SPORT",502.56,6.944381111880313,34],["OTHER EXPENSES",492.7,6.808135493918,19],["Other",399.81,5.524580174189884,0]];
var plot1 = jQuery.jqplot ('budgetGraph', [budgetGraph],
{
seriesDefaults: {
// Make this a pie chart.
renderer: jQuery.jqplot.PieRenderer,
rendererOptions: {
},
seriesColors: graphColours.pie
},
legend: {
renderer: jQuery.jqplot.PieLegendRenderer,
show: true,
renderOptions: {
numberColumns: 3
},
location: 'e',
placement: 'outside',
border: 'none'
},
grid: {
drawGridLines: false, // wether to draw lines across the grid or not.
gridLineColor: 'transparent', // CSS color spec of the grid lines.
background: 'transparent', // CSS color spec for background color of grid.
borderColor: 'transparent', // CSS color spec for border around grid.
borderWidth: 0.0, // pixel width of border around grid.
shadow: false // draw a shadow for grid.
}
}
);
You can remove the outline by overriding the css class:
.jqplot-table-legend-swatch-outline { border: 0 solid #CCCCCC;}
For your second question you can use the "labels" option of the legend:
legend: {
show: true,
location: 'ne',
placement: "outside",
labels: legendLabels
}
and before calling the jqplot function populate the legendLabels array like this:
var legendLabels= ['label1 with data or %', 'label2 with data or %', 'label3 with data or %'];

How to use Jqplot to show two groups of differently colored bars in the same stacked bar chart

I want to make a bar chart with two sets of stacked bars which are grouped together to compare the two groups of stacked bars. This should be displayed in the following manner:
I have gone through this link
But it didn't help me plot something like you see in the above image. I even tried sending two data sets like [[s1, s2, s3], [s4, s5, s6]] But it didn't help me plot the chart.
Does anyone know how to do it?
Any help will be greatly appreciated.
Thanks in advance.
Setting the option stackSeries: true will create the desired display for bar charts.
Official sources:
jqPlot Source code: source code, version 1.0.8r1250 of
2013-03-27. For this issue, src/jqplot.core.js lines 2499, 2563, and 2649.
jqPlot Documentation: It says that the API Documentation is most accurate. you can also see the webpage, README.txt,
optionsTutorial.txt, jqPlotOptions.txt, jqPlotOptions.txt,
jqPlotCssStyling.txt, usage.txt, changes.txt in the 1.0.8r1250
general release
The jqPlot documentation is not up to date so I took a look at the source code. Unfortunately, there is no way to directly have two sets of bars with a stacked-bar chart. The jqPlot.stackSeries property is only a boolean value. It's only function is to tell jqPlot to stack each series on top of each other for as many bars as there are values in the different series. Each series is plotted one value per bar with the first series being on the bottom. In other words, all [0] values are plotted in the first bar, [1] values in the second, etc. The amount shown within the bar is the sum of the [n] value for the current series and all prior series. There is no way to specify that there are two, or more, groupings of series. The capability to do what is desired just does not exist in jqPlot.
But you can accomplish what you desire:
The fact that jqPlot does not natively support what you want does not mean that you can not do it, merely that you need to get creative.
The graph you desire can be looked at as being two separate graphs that have been overlaid upon each other with spacing between the bars on the individual graphs permitting enough space (seriesDefaults.rendererOptions.barMargin) for the bars from the other graph to be overlaid next to them.
You can use jqPlot to create:
That graph has the scale, background and grid-lines you desire set to be visible. Note that the graph has an extra bar in it. This is needed to provide enough background and grid-lines for the last bar provided by the other graph.
You can also use jqPlot to create the second graph:
This graph has the scale and grid-lines set in jqPlot to not be visible.
seriesDefaults.axes.xaxis.tickOptions.show = false;
seriesDefaults.axes.yaxis.tickOptions.show = false;
etc.
The background is set to be transparent. Note that you are going to need to offset the position of this graph somewhat to the right when positioning the <div> relative to the first graph.
Overlaid, you end up with:
You then use a blank <div> with the same background color as the background color of your webpage and overlay that to cover the extra bar on the first graph, but leaving enough of the first graph's background and grid-lines to extend a bit past the last bar of the second graph.
You will end up with:
You can see a working solution at at JSFiddle using jqPlot 1.0.8r1250.
Comparing the original request vs. the final version of the graph produced using this method you can see that they are very close:
Between the two the most noticeable difference is the larger space between the Y-axis in the jqPlot version. Unfortunately, there does not appear to be an option to reduce that amount for stacked bar charts.
Note that the lack of a border on the right of the graph this code produces is intentional because it did not exist in the original request. Personally, I prefer having a border on the right side of the graph. If you change the CSS a bit, that is easy to obtain:
My preferred version of the graph includes a border on the left and balances the whitespace:
You can see a working JSFiddle of this version.
All-in-all it is not that difficult. It would, of course, be easier if jqPlot supported multiple sets of bars. Hopefully it will at some point. However, the last release was 2013-03-27 and there does not appear to have been any development work after that time. Prior to that there were releases every few months. But, jqPlot is released under the GPL and MIT licenses so anyone could continue the work.
