Please see the image below. The pie chart only shows category 2011, 2012 & 2013. The row bar chart only shows Mr. A, Mr.B & Mr. C.
How can I edit my code below to make the labels display what is shown in the tooltips that are displayed on hover?
I want to display all labels like "2011: 80" instead of "2011" (using the selection to change the value).
Also "2012: 90" instead of "2012", and "2013: 80" instead of "2013".
The rest of charts should also display the names with values. How can I change the code to achieve this?

The tooltip text is controlled by .title(), because title is the SVG tag for tooltips, and the label is controlled by .label().
Pass each one of these a function that takes the data {key, value} and returns the text you want.
The default tooltip/title function is d => d.key + ': ' + d.value.
A lazy way to copy the title function to the label is
yearRingChart
.label(yearRingChart.title())
Or, for more control, define it yourself:
.label(d => d.key + ': ' + d.value)

I have created a very simple test case to use the D3.JS v5 stratify method. Everything looks to be in order based on similar code but mine fails and I am not sure why. Can anyone help?

The issue is happening here:
data.forEach(function(d) {
d.pk = +d.pk;
d.fk_staff = +d.fk_staff;
});
Some of the data has an empty string as d.fk_staff. When the empty string is coerced to a number it becomes 0, and there is no data with d.pk equals to 0, hence the error.
A simple fix is to not coerce the empty string:
data.forEach(function(d) {
d.pk = +d.pk;
d.fk_staff = d.fk_staff === '' ? '' : +d.fk_staff;
});

There is this example that shows how you can make an elastic X axis that removes the empty bins using a fake group and the chart.elasticX(true) method.
I'm trying to make this work with a stacked barchart but I face a problem. I have slightly modified the code of the above example to use a stacked group for the barchart. (I have added an Earned column in the data, made a fake group for it and assigned it to the chart.stack method). But for certain "Earned" values there is a d3.js error:
Uncaught TypeError: Cannot read property '1' of undefined.
#
Update:
This issue is related with this answer which states that "The stack method expects your data to be equally length-ed". It is also related with this answer that proposes the creation of a combined group to overcome the problem.

Here is the modified example code

However if you change the Earned values to
var spendData = [
{Name: 'Mr A', Spent: '$40', Earned: '$70', Year: 2011},
{Name: 'Mr B', Spent: '$10', Earned: '$20', Year: 2011},
{Name: 'Mr C', Spent: '$40', Earned: '$40', Year: 2011},
{Name: 'Mr A', Spent: '$70', Earned: '$170', Year: 2012},
{Name: 'Mr B', Spent: '$20', Earned: '$30', Year: 2012},
{Name: 'Mr B', Spent: '$50', Earned: '$50', Year: 2013}, // This is the only change Earned from '$30' to '$50'
{Name: 'Mr C', Spent: '$30', Earned: '$70', Year: 2013}
]
Then it works fine.
I face the same d3 error for my case so I tried to reproduce it with a simple example.
There is also this related question
Welp, you found the answer already; it's just a matter of applying it.
This is indeed the same question that can be solved with a combined group.
combinedGroup = combine_groups(nonEmptyHist,nonEmptyEarnHist)
function sel_stack(i) {
return function(d) {
return d.value[i];
};
}
spendHistChart
.group(combinedGroup, 'spend', sel_stack(0))
.stack(combinedGroup, 'earn', sel_stack(1))
I don't know of another way to deal with this; d3.stack requires arrays of the same size and dc.js will also assume that the key/value arrays correspond to each other.

I am using kendo line chart in my application, the x axis values/labels are overlapping. The xAxis.labels.step property doesn't work in my case as the categoryaxis is bind to an datasource that can contain a date difference in days/moths/years. How can i avoid ovelapping?
I have used rotation to fix this issue, but is there any other approach?

chart.options.categoryAxis.labels.step = 5;

else {

Thanks in Advance.

Here I'm not sure about how to call the dojo code in enyo.
and
depends.js :
enyo.depends(
"source/charts1.js",
"lib/Chart2D.js",
"lib/widget/Chart2D.js",
"lib/blue.js",
"lib/dojo.js"
);
Now I'm getting the following errors :
error: Uncaught ReferenceError: dojo is not defined, Chart2D.js:1
[20110818-09:33:13.136736] error: Uncaught ReferenceError: dojo is not defined, widget/Chart2D.js:1

[20110818-09:33:13.150707] error: Uncaught TypeError: Cannot read property 'graphs2' of undefined, index.html:10
It is working fine when I use it as a .HTML file with the same code in browser.

Please help me in working with this in Enyo.
Thanking You.
Kind Regards,
Harry.
I don't think you have to modify the Dojo code. In Enyo, you have to tell the framework where it has to look for included JS files. Yo do so editing the depends.js file.
The index.html:
<!doctype html>
<html>
<head>
<title>Canvas Demo</title>
<script src="../../../../1.0/framework/enyo.js" type="text/javascript"></script>
</head>
<body>
<script type="text/javascript">
new enyo.Canon.graphs2().renderInto(document.body);
</script>
</body>
</html>
and depends.js:
enyo.depends(
"lib/dojo/dojo.js" ,
"source/charts1.js"
);
You'll have to copy everything Dojo needs to work (dojo, dojox, dijit) into lib, and check enyo paths.
I get a Dojo error when creating the new Chart2D object, and I'm not a Dojo expert to fix this. It's in the line:
var chart1 = new dojox.charting.Chart2D("simplechart");
I've modified your code:
enyo.kind({
name: "enyo.Canon.graphs2",
kind: enyo.Control,
components: [
{kind: "PageHeader", content: "bargraph"},
//{style: "padding: 10px", content: "Note: In the browser, you can press ctrl-~ to display the app menu."},
{kind: "Button", caption: "display graph", onclick: "displayGraph", flex: 1},
],
displayGraph: function() {
dojo.require('dojox.charting.Chart2D');
dojo.require('dojox.charting.widget.Chart2D');
dojo.require('dojox.charting.themes.PlotKit.green');
/* JSON information */
var json = {
January: [12999,14487,19803,15965,17290],
February: [14487,12999,15965,17290,19803],
March: [15965,17290,19803,12999,14487]
};
/* build pie chart data */
var chartData = [];
dojo.forEach(json['January'],function(item,i) {
chartData.push({ x: i, y: json['January'][i] });
});
/* resources are ready... */
dojo.ready(function() {
//create / swap data
var barData = [];
dojo.forEach(chartData,function(item) { barData.push({ x: item['y'], y: item['x'] }); });
var chart1 = new dojox.charting.Chart2D("simplechart"); // HERE IS THE PROBLEM
chart1.setTheme(dojox.charting.themes.PlotKit.green);
chart1.addAxis('x', { fixUpper: 'major', includeZero: false, min:0, max:6 });
chart1.addAxis('y', { vertical: true, fixLower: 'major', fixUpper: 'major' });
chart1.addPlot('default', {type: 'Columns', gap:5 });
chart1.addSeries('Visits For February', chartData, {});
var anim4b = new dojox.charting.action2d.Tooltip(chart1, 'default');
var anim4c = new dojox.charting.action2d.Shake(chart1,'default');
chart1.render();
// var legend4 = new dojox.charting.widget.Legend({ chart: chart1 }, 'legend3');
});
}
});
The object doesn't get instantiated. Got null pointer :-(
