Give a Linear Gauge custom labels - kendo-ui

I have a kendo linear gauge defined like this...
$("#gauge").kendoLinearGauge({
pointer: {
value: 4.5,
shape: "arrow"
},
scale: {
majorUnit: 1,
minorUnit: 1,
max: 6,
ranges: [
{
from: 0,
to: 1,
color: "#ffc700"
}, {
from: 1,
to: 2,
color: "#ff7a00"
}, {
from: 2,
to: 3,
color: "#c20000"
}, {
from: 3,
to: 4,
color: "#FF0000"
}, {
from: 4,
to: 5,
color: "#00FF00"
}, {
from: 5,
to: 6,
color: "#0000FF"
}
]
}
});
And this produces a gauge that looks like this...
What I want to do is replace the numeric labels with string values like "Unverified", "Verified", "Open", etc so that I end up with something more akin to this...
I'm fairly confident that I should be able to do this using a template, but I can't get even the simplest of examples (including the one shown below from the telerik website) to work.
$("#linear-gauge").kendoLinearGauge({
scale: {
labels: {
// labels template
template: "#= value #%"
}
}
});
Can anyone offer any suggestions?

Create a template function
template: function (rec) {
var label;
switch (rec.value) {
case 0:
label = 'un verified';
break;
case 1:
label = 'verified';
break;
default:
label = 'open';
}
return label;
}

You need to use a second dataset to achieve this:
Then you can fill null values in both datasets where you dont use the values of that dataset, so null values on the places where value is negative in positive dataset and vice versa in other one.
Then you can use the property skipNull to make it so the bars dont take up space:
const options = {
type: 'bar',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, null, 3, 5, null, 3],
backgroundColor: 'green'
},
{
label: '# of Points',
data: [null, -11, null, null, -3, null],
backgroundColor: 'red'
}
]
},
options: {
skipNull: true
}
}
const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<body>
<canvas id="chartJSContainer" width="600" height="400"></canvas>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.7.1/chart.js"></script>
</body>
should be this part
label: ['Attendence', 'newLabel', 'xxx'],
under
const ctx = document.getElementById('chartJsDiv').getContext('2d');

c3js - Grid lines showing on top of content

I've been trying to make the x-axis grid lines to be behind the content of a c3js bar chart.
I toyed with z-index which didn't work. I tried with opacity which didn't work either.
Here is the JSFiddle with the code I was using.
https://jsfiddle.net/chaitanya81/rvhb0fy4/1/
var chart = c3.generate({
bindto: '#chart',
data: {
x : 'x',
columns: [
['x', 'M','T','W','TH','F','SA','SU'],
['revenue', 200, 300, 200, 400, 500, 700, 600.56]
],
type: 'bar'
},
color: {
pattern: ["#ff9900"]
},
axis: {
x: {
type: 'category', // this needed to load string x value
tick: {
outer: false
}
},
y: {
tick: {
outer: false
}
}
},
grid: {
x: {
lines: [
{value: "M"},
{value: "T"},
{value: "W"},
{value: "TH"},
{value: "F"},
{value: "SA"},
{value: "SU"}
]
}
},
bar: {
width: {
ratio: 0.4
}
},
legend: {
hide: true
},
tooltip: {
contents: function (data, defaultTitleFormat, defaultValueFormat, color) {
var $$ = this, config = $$.config,
titleFormat = config.tooltip_format_title || defaultTitleFormat,
nameFormat = config.tooltip_format_name || function (name) { return name; },
valueFormat = config.tooltip_format_value || defaultValueFormat,
text, i, title, value;
for (i = 0; i < data.length; i++) {
if (! (data[i] && (data[i].value || data[i].value === 0))) { continue; }
if (! text) {
title = titleFormat ? titleFormat(data[i].x) : data[i].x;
text = "<div id='tooltip' class='d3-tip'>";
}
value = valueFormat(data[i].value, data[i].ratio, data[i].id, data[i].index);
text += "<span class='value'>$" + value + "</span>";
text += "</div>";
}
return text;
}
},
transition: {
duration: 1000
}
});
Any one tried this with c3js charts?
Thanks in Advance.
You can set grid.lines.front to false
var chart = c3.generate({
bindto: '#chart',
data: {
...
},
grid: {
lines: {
front: false
}
}
});
https://jsfiddle.net/Yosephsol/bwu70xgq/
The grid line layer comes over the chart elements (bars) layer, and SVG the z-index is set by the order of the elements in the document.
You could use your regions to give the same effect. One way is
CSS
.border {
stroke: #000;
fill: transparent;
}
.whiteborder {
stroke: white;
fill: transparent;
}
Script
regions: [
{ axis: 'x', start: -0.5, end: 0, class: 'border' },
{ axis: 'x', start: -0.5, end: 1, class: 'border' },
{ axis: 'x', start: -0.5, end: 2, class: 'border' },
{ axis: 'x', start: -0.5, end: 3, class: 'border' },
{ axis: 'x', start: -0.5, end: 4, class: 'border' },
{ axis: 'x', start: -0.5, end: 5, class: 'border' },
{ axis: 'x', start: -0.5, end: 6, class: 'border' },
{ axis: 'x', start: -0.5, end: 6.5, class: 'whiteborder' },
],
The last line is to get rid of the top border (you can't style different borders of a rect differently - there's an alternative [hack] using stroke-dasharray, but it depends on the relative height and width of your regions)

c3.js how to remove line with tooltip?

I am creating a line chart using c3.js. I want to remove the default indicator line to x-axis with the tooltip.
I have tried tooltip formatting but the line remains same.
How this can be done?
grid:{
focus:{
show:false
}
}
May be at that time when person answer this question config parameter not provided but now you can do it through above mention configuration. Reference http://c3js.org/reference.html#grid-focus-show
Example code below
var chart = c3.generate({
data: {
columns: [
['data1', 30, 200, 100, 400, 150, 250],
['data2', 50, 20, 10, 40, 15, 25]
]
},
grid:{
focus:{
show:false
}
}
});
Just override the following css property in .c3-xgrid-focus class:-
.c3-grid .c3-xgrid-focus {
visibility : hidden !important;
}
I could not quickly find a config parameter to turn this feature off in the api doc.
point: {
show: false
},
False to hide the points and true for show the points
Note:
Make sure that you are going to write this after the loading the data and along with your other settings in c3 Generate function
Here is the Example:
http://c3js.org/reference.html#point-show
In below code I have highlighted the code with a comment:
var chart = c3.generate({
bindto: '#CYCLE_CHART',
data: {
columns: [
["Cycletime"].concat(objCycle.cData), ["Downtime"].concat(objDowntime.dData), ["StdCycletime"].concat(objStdCycle.stdCData), ["StdLoadunloadtime"].concat(objStdLUtime.stdLUData),
],
type: 'spline',
types: {
Cycletime: 'bar',
Downtime: 'bar'
},
names: {
Cycletime: 'Cycle time',
Downtime: 'Load time',
StdCycletime: 'Std Cycle time',
StdLoadunloadtime: 'Std Load time'
},
},
axis: {
x: {
label: {
text: 'Cycles',
position: 'outer-center'
},
max: 10,
min: 1,
},
y: {
label: {
text: 'Seconds',
position: 'outer-middle'
},
max: Y_axis,
min: 1,
}
},
// Here!
point: {
show: false
},
tooltip: {
show: true
}
});
According to BonifatiusK´s comment, you should hide them by editing the chartOptions.
{
tooltip: {
show: false
}
}
Overriding CSS properties of c3 is not a good idea.

In kendo UI how to draw vertical line in a line chart

How to draw a vertical line in a line chart using Html5 and kendo UI ? can anyone help me out to solve this problem ?
Try this:
// let chart be the id
$("#chart").kendoChart({
categoryAxis: {
notes: {
line: {
length: 300
},
data: [{
value: new Date(2012, 0, 3),
label: {
text: "-" //text you want to show
}
}]
}
}
});
Demo: http://jsbin.com/obuweca/26
/* WITHOUT CIRCLE */
$("#chart").kendoChart({
categoryAxis: {
notes: {
line: {
length: 300
},
icon: {
border: {
width: 0
}
},
// Initial notes
data: [{
value: new Date(2012, 0, 3)
}]
}
}
});
DEMO: http://jsbin.com/obuweca/29/
In kendo documentation is example how do draw custom lines on chart. Horizontal and vertical.
http://docs.telerik.com/kendo-ui/controls/charts/how-to/custom-plot-bands
You can customize lines by editing stroke:
stroke: {
color: "red",
width: 1,
dashType:"dash"
}
You can also try to use the column-Chart.
Just extend the series:
series: [{
type: "line",
field: "value",
categoryField: "date"
},
{
type:"column",
field: "valueColumn",
gap: 300
}]
and the dataSource.data with a new field like: valueColumn.

Initializing cytoscape

being new to cytoscapeweb 2, i am following one of the provided example in order to learn how to use the API.
i cant make it work and firebug reports the following message:
Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)
var n = this.nodesGroup.getBBox();
in my html document, the cytoscapeweb div is embedded in a jquery tab widget (just to provide context)
somewhere in my.html
<div id="tabs">
<ul>
<li>Interactors Selection</li>
<li>Interactome Builder</li>

Did i miss something obvious?
If so, all apologies.
(1) Don't put alerts in your code like that even when you're testing. It can break asynchronous code, like initialising Cytoscape Web or doing an AJAX call. Use console.log() instead.
(2) You're probably hiding the Cytoscape Web div, cy, with the tabs. You shouldn't be using display: none;, because the Cytoscape Web viewport will then be 0x0 px. Try something like position: absolute; left: -9999px; or similiar for hiding. This entails modifying whatever class name jQuery uses for hidden tabs (probably .ui-state-hidden or something similar).
(3) I'll look into making the renderer code more tolerant of hidden Cytoscape Web divs.
I have a better solution to this problem:
Execute jquery tab just after all of the graphs are loaded.
http://cytoscape.github.io/cytoscape.js/#core/events/cy.ready
for(var t = 0, tot=pageList.length; t<tot; t++) //draw graph for all pages
{
var currPage = pageList[t];
getData(currPage);
}
function getData(currPage)
{
//initiate graph, do stuff...
//graph ready
window[currPage + "Container"].ready(function(e)
{
if (currPage.indexOf(lastPage) != -1)//executetabsafterlastgraphisdrawn
{
setTabs();
}
});
}
