Kendo UI Diagram - content text values - kendo-ui

I'm using shapeDefaults in constructing the diagram. The content -> text value should refer to the node's name property. For example, if the node object is:
var data = [{
designation: "CEO",
name: "Mitchell Johnson",
manages: [{
designation: "Vice President",
name: "Smith Cooper",
manages: [{
designation: "Director",
name: "Andrew Walker"
}, {
designation: "Director",
name: "Robert Thompson"
}]
}, {
designation: "Vice President",
name: "Harris Jones",
manages: [{
designation: "Director",
name: "Edward Collins"
}, {
designation: "Director",
name: "Thomas Wang"
}]
}]
}];
Here content -> text should refer to 'name' attribute and display it in the center.

Make sure you add 'shapeDefaults' to the diagram config:
shapeDefaults:
{
visual: visualTemplate
},
In the function visualTemplate, add your way of marking it up like :
function visualTemplate(options)
{
var dataviz = kendo.dataviz;
var g = new dataviz.diagram.Group();
var dataItem = options.dataItem;
g.append(new dataviz.diagram.Rectangle(
{
width: 210,
height: 75,
stroke:
{
width: 0
},
fill: dataItem.color
}));
g.append(new dataviz.diagram.TextBlock(
{
text: dataItem.name,
x: 5,
y: 20,
color: "#fff"
}));
}
if you ever get to know how to center the text, please tell me. I am looking for it :)

KendoChart with stripes bars

I am trying to create a KendoChart, then I wanted to have the bars to be on a stripes format. How to do that? I think I need to add "style" in "seriesDefaults" section or in the "series" section.
I have the code snippets below:
$("#chart").kendoChart({
title: {
text: "Sample"
},
seriesDefaults: {
type: "column"
},
series: [{
name: "India",
data: [3.907, 7.943, 7.848]
},{
name: "World",
data: [1.988, 2.733, 3.994]
}],
valueAxis: {
labels: {
format: "{0}%"
},
line: {
visible: false
},
axisCrossingValue: -10
},
categoryAxis: {
categories: [2002, 2003, 2004],
majorGridLines: {
visible: false
},
labels: {
rotation: "auto"
}
},
tooltip: {
visible: true,
format: "{0}%",
template: "#= series.name #: #= value #"
}
});

How to solve incorrect grouped bar chart in Chrome?

I'm creating a grouped bar chart like this:
$("#chart").kendoChart({
dataSource: {
data: rawdata,
group: { field: "Serie" },
},
legend: {
position: "top"
},
plotArea: {
background: "white",
},
seriesDefaults: {
type: "column",
style: "smooth",
stack: true
},
series: [
{
field: 'Valor1',
labels: {
visible: true,
background: '',
format: 'p1',
color: 'white',
position: 'center'
},
}
],
valueAxis: {
max: 1,
labels: {
format: "p2"
},
line: {
visible: false
},
axisCrossingValue: -10,
},
categoryAxis: {
field: "Segmento",
majorGridLines: {
visible: false
}
},
tooltip: {
visible: true,
template: "#= series.name # <br /> " +
"Valor = #= kendo.format('{0:p2}', value) # <br/> " +
"Tooltip = #= dataItem.Tooltip # ",
}
});
My data has four properties: Serie, Segmento, Valor1, Tooltip. Example of one data point:
{
"Serie": "S1",
"Segmento": "C1",
"Valor1": 0.31500380634422465,
"Tooltip": 20,
}
The values of the stack bar are incorrect in chrome but in firefox and ie it's fine.

Here is a live demo: http://trykendoui.telerik.com/anET/9
How can i solve this?
This is a problem with Chrome's implementation of Array.sort; see this discussion.
You can fix it by sorting the data source explicitly:
dataSource: {
data: rawdata,
group: { field: "Serie" },
sort: [{ field: "Serie", dir: "asc"}, { field: "Segmento", dir: "asc"} ]
},

cant add notes to categoryAxis with kendo charts

Is there a possibility to add notes on the categoryAxis in a Kendo Chart.
As seen in the documentation it should be possible, but even after setting every single option i dont see any notes. I couldn't find any example of somebody doing that. Has anybody managed or used this feature?
my try on jsFiddle
categoryAxis: {
field: "age",
justified: true,
majorGridLines: {
visible: false
},
minorGridLines: {
visible: false
},
min: 10,
max: 30,
labels: {
step: 5
},
notes: {
data: [{
value: { age: 15 },
position: "top",
icon: {
visible: true,
size: 16,
type: "circle",
background: "#585858",
border: {
color: "#FFFFFF"
}
},
line: {
length: 16
},
label: {
visible: false,
text: " "
}
}]
}
}
Thank you
The value property for notes on the categoryAxis appears to represent each category value.
Here's an example notes configuration:
notes: {
label: {
template: "Value: #: value #"
},
icon: {
visible: true,
size: 16,
type: "circle",
background: "#585858",
border: {
color: "#FFFFFF"
}
},
line: {
length: 16
},
data: [{ value: 1}, { value: 5 },{ value: 10 }, { value: 15 }, { value: 20 }]
}

Kendo line chart notes aren't shown

I use kendo dataviz chart and want to add notes. This is the code I've written
$("#resultChart").kendoChart({
dataSource: resultsDataSource,
title: {
text: "Results"
},
legend: {
position: "bottom"
},
chartArea: {
background: ""
},
seriesDefaults: {
type: "line"
},
series: [{
field: "Points",
name: "Points",
noteTextField: "EventName",
notes: {
label: {
position: "outside"
},
position: "bottom"
}
}],
valueAxis: {
labels: {
format: "{0}"
},
line: {
visible: false
},
axisCrossingValue: -10
},
categoryAxis: {
field: "EventDate",
majorGridLines: {
visible: false
}
},
tooltip: {
visible: true,
format: "{0}%",
template: "#= series.name #: #= value #"
}
});
Everything is working as needed, i.e. chart is drawn with appropriate data, but notes aren't shown.
Please help me find out why notes aren't shown, if there's data in "EventName" property(I've checked). I want to mention that I am using kendo ui 2013.1.514 version.
Thank you in advance.
In your series definition, you have noteTextField: "EventName", which means you must have the property EventName defined for each item in your DataSource, as #ccsakuweb alluded to.
This means that in your DataSource, the data items should look something like this:
var data = [
{ Id: 1, Name: "Result #1", EventName: "Note 1" },
{ Id: 2, Name: "Result #2", EventName: "Note 2" }
];
Kendo's documentation about the Notes feature is located at http://docs.telerik.com/kendo-ui/dataviz/chart/notes .

kendo grid how to set the schema.model with a foreign key field

need help about adding a new recort in a kendo grid.
I have a grid with a foreign key field. The grid is populated by a json data with subobject, returned from a webmethod. it looks like this:
[
{
"classe_iva": {
"id_classe_iva": 5,
"desc_classe_iva": "Esente",
"note_classe_iva": null
},
"id_iva": 37,
"desc_iva": "bbb",
"codice_iva": "bbb",
"imposta": 2,
"indetr": 2,
"id_classe_iva": 5,
"note": "dddddfsf",
"predefinito": false,
"id_company": 4
},
{
"classe_iva": {
"id_classe_iva": 6,
"desc_classe_iva": "Escluso",
"note_classe_iva": null
},
"id_iva": 52,
"desc_iva": "o",
"codice_iva": "jj",
"imposta": 1,
"indetr": 1,
"id_classe_iva": 6,
"note": "l",
"predefinito": false,
"id_company": 4
}
]
and this is the schema.model used in the kendo datasource:
model = {
id: "id_iva",
fields: {
id_iva: { type: "string", editable: false },
desc_iva: { type: "string" },
codice_iva: { type: "string" },
imposta: { type: "number" },
indetr: { type: "number" },
id_classe_iva: {type: "string"},
note: { type: "string" },
predefinito: { type: "boolean" },
id_company: { type: "number" }
}
}
.. and below is shown the grid columns format:
toolbar = [{
name: "create",
text: "Aggiungi nuova aliquota IVA"
}];
columns = [
{ field: "desc_iva", title: "Descrizione", width: 45 },
{ field: "codice_iva", title: "Codice", width: 45 },
{ field: "imposta", title: "Imposta", width: 45 },
{ field: "indetr", title: "Indetr", width: 45 },
{ field: "classe_iva.desc_classe_iva", title: "Classe IVA", width: 200, editor: categoryDropDownEditor, template: "#= classe_iva ? classe_iva.desc_classe_iva : 1 #", defaultValue: { id_classe_iva: 1, desc_classe_iva: "Acq. Intra-UE" } },
{ field: "note", title: "Note", width: 45 },
{
command: [{
name: "destroy",
text: "Elimina",
confirmation: "Sei sicuro di voler eliminare questa voce?"
} ,
{
name: "edit",
text: {
edit: "Modifica",
update: "Aggiorna",
cancel: "Cancella"
}
}
]
}
];
Theese settings works fine when i edit a row, and the grid shows the right content into the combobox field.
The problem is when i click on the "add new record" button, because when it tries to add a new row, it doesn't find the subobjects field "classe_iva".
if i change the column.field into this
{ field: "id_classe_iva", title: "Classe IVA", width: 200, editor: categoryDropDownEditor, template: "#= id_classe_iva ? id_classe_iva : 1 #", defaultValue: { id_classe_iva: 1, desc_classe_iva: "Acq. Intra-UE" } },
{ field: "note", title: "Note", width: 45 }
the add button works fine, but when the grid is loaded, the column id_classe_iva doesn't shows me the classe_iva.desc_classe_iva field...
how can i fix the issue??^?
thanks in advance.
to fix this issue, i used a workaround:
the error was thrown because, in the declaration of the field.template there where a not declared variable (classe_iva):
{ field: "id_classe_iva", title: "Classe IVA", width: 200, editor: categoryDropDownEditor, template: "#= classe_iva ? classe_iva.desc_classe_iva : 1 #", defaultValue: { id_classe_iva: 1, desc_classe_iva: "Acq. Intra-UE" } },
then, i declared a global variable
var classe_iva;
in this way, when i add a new record, the code doesn't throw any errors, and by the ternary if, the default value is set.
hope it will help someone.
