I am trying to create bar chart using ng2-chart in angular 5. It is creating fine but i think i am missing some configuration due to which i am getting percentage calculation on top of maximum 2 bars. i want to remove these percentage
i am using ng2-charts(1.6.0), chart.js(2.7.2) in package.json.
I have tried configuration available on chartjs.org for bar chart but not able to remove the percentage calculation for those bars.
In html
<canvas baseChart
height='260px'
[datasets]="barChartData"
[labels]="barChartLabels"
[options]="barChartOptions"
[colors]="chartColors"
[legend]= "false"
[chartType]="barChartType">
</canvas>
In Component
public barChartType: ChartType = 'bar';
public barChartOptions: ChartOptions = {
responsive: true,
scales: { xAxes: [{}], yAxes: [{ticks: {beginAtZero: true}}] },
plugins: { datalabels: { anchor: 'end', align: 'end', } }
};
public barChartData = [ { data: [7,4,1,5,3,1,2,1]} ],
public barChartLabels = ['25/03','26/03','27/03','28/03','29/03','30/03','31/03','01/04','02/04',],
public chartColors = [ {backgroundColor: '#fa9cb0'} ]
i want simple bar without those random percentage on top of those bar.
Just for info, it is coming for only small value. For values like
[12,22,34,53,65,73,23,45]
It is fine.
Please let me know, how can i remove those percentage from top of bar. Is there any other configuration i need to use??
I futher looked in the issue and found out that in my project global plugin was created which was wrongly implemented for every type of chart without any configrable property.
Chart.plugins.register({ // plugin implementation });
Refering to this link ChartJs Plugin
You can use the plugin: 'chartjs-plugin-labels' to solve the issue, here is the info to add the plugin to your Angular project:
https://emn178.github.io/chartjs-plugin-labels/
After you have the plugin installed in your project you have to add the library in the .ts file of the chart with this code snippet:
import 'chartjs-plugin-labels';
and in the plugins variable section add this code also:
labels: {
render: false
}
Need to import ChartDataLabels and then unregister 'ChartDataLabels' plugin
import ChartDataLabels from 'chartjs-plugin-datalabels';
Chart.plugins.unregister(ChartDataLabels); // on ngAfterViewInit

I'm working with Docusaurus to create a documentation site for 3 different education courses - all within the docs folder.
So I'm looking for a way to have the version be different across folders in there, or figure out what the best strategy for this is.
Right now, in my docusaurus.config.js I have:
module.exports = {
presets: [
'#docusaurus/preset-classic',
docs: {
lastVersion: 'current',
versions: {
current: {
label: '1.0.0',
path: '1.0.0',
},
},
},
],
};
But I'm not sure how to keep track of 3 different versions across 3 different docs all within the same site.
Swizzle the navbar via wrapping
yarn run swizzle #docusaurus/theme-classic NavbarItem/DocsVersionDropdownNavbarItem -- --wrap
Modify the swizzled component like so:
src/theme/NavbarItem/DocsVersionDropdownNavbarItem.js:
import React from "react";
import DocsVersionDropdownNavbarItem from '#theme-original/NavbarItem/DocsVersionDropdownNavbarItem';
import { useLocation } from '#docusaurus/router';
export default function DocsVersionDropdownNavbarItemWrapper(props) {
const { docsPluginId, className, type } = props
const { pathname } = useLocation()
/* (Custom) check if docsPluginId contains pathname
Given that the docsPluginId is 'charge-controller' and the routeBasePath is 'charge-controller', we can check against the current URI (pathname).
If the pathname contains the docsPluginId, we want to show the version dropdown. Otherwise, we don't want to show it.
This gives us one, global, context-aware version dropdown that works with multi-instance setups.
You want to declare a version dropdown for each plugin in your navbarItems config property for this to work well.
const doesPathnameContainDocsPluginId = pathname.includes(docsPluginId)
if (!doesPathnameContainDocsPluginId) {
return null
}
return <DocsVersionDropdownNavbarItem {...props} />;
}
For this to work, you need to have your documentation (based on products) split up using multi-instances: (https://docusaurus.io/docs/docs-multi-instance#docs-navbar-items)
Note that the preset docsPlugin ID always is "default".
You can try to use
import {
useActivePluginAndVersion,
} from '#docusaurus/plugin-content-docs/client';
const version = activePluginAndVersion.activeVersion.name; // use label instead of name if issues arise.
instead to get the current docsPluginId, name or label.
This would be the more "robust" solution I think. That said, we do use the solution I provided above as-is and it works fine for now.
I'm using the highcharts-vue wrapper within my vue project. Things are going smooth except for the fact that I can't get the viewFullscreen option to work.
I've set things up following the docs and included the following within my main.js
import exportingInit from 'highcharts/modules/exporting'`
exportingInit(Highcharts);
The export function is working within my charts. For every chart I've set up the options as follow:
exporting: {
buttons: {
contextButton: {
menuItems: ['viewFullScreen', 'downloadPNG', 'downloadJPEG', 'downloadPDF']
}
}
}
alle the buttons ar visible and working except for the viewFullscreen button. that one isn't showing.
Following the docs from the highcharts api there isn't anything mentioned about having to include extra options or so to make use of the vieFullscreen mode.
Any thoughts on this?
You need to change the first string from viewFullScreen to viewFullscreen:
exporting: {
buttons: {
contextButton: {
menuItems: ['viewFullscreen', 'downloadPNG', 'downloadJPEG', 'downloadPDF']
}
}
}

I am only a month old with extjs and still experimenting. My question is: I have a grid panel and within it the 'tools' config options. I am using this to enable/disable a Ext.grid.feature.Grouping variable. The 2 handler functions have the logic to disable/enable the 2 views by clicking on the 2 'cross' buttons that appear on the right side of the header. The logic is fine. However, I would like to display my set of custom images in place of the 'cross' buttons. Can this be done? If yes, how? Do I need to make some changes in the css code for that?
I have looked into the documentation and also done a good search but nothing seems to answer my question.
Specify a custom type config on your tools:
Ext.create('Ext.grid.Panel', {
...
tools: [
{
type: 'enable-grouping',
handler: function() {
...
}
},
{
type: 'disable-grouping',
handler: function() {
...
}
}
]
});
Then define the following classes in a stylesheet to style your new tools:
.x-tool-enable-grouping {
background-image: url('path/to/tool/image/enable-grouping.png');
}
.x-tool-disable-grouping {
background-image: url('path/to/tool/image/disable-grouping.png');
}
The size of a tool image should be 15 x 15 px
Within Sencha Touch, is it possible to define a default UI , like "light" or "dark", that applies to all components (unless overwritten explicitly)?
The aim is to avoid having to declare ui: "dark", or any custom UI that is made, for every element.
Cheers!
You can try this:
Ext.apply(Ext.Component.prototype, {
getUi: function() {
var defaultUi = 'light';
// value of [this.config.ui] is ignored here
// we can use something like forcedUi
return (this.forcedUi) ? this.forcedUi : defaultUi;
}
})
The disadvantage of this code is that we need to specify another variable for applying ui different from 'light' (because variable 'ui' via getUi() will always return 'light'):
...
items: [{
xtype: 'button',
forcedUi: 'dark'
}]
...
I am stuck on Touch 1.1 so sunsay's solution didn't work for me, but this did:
Ext.CustomToolbar = Ext.extend(Ext.Toolbar,
{
ui:'app'
});
Ext.reg('toolbar', Ext.CustomToolbar);
So, it's still component-by-component-type, but not component-by-component-instance. And since you can overwrite the "reg", no need for custom x-types all over the place, either.
I assume that you know about sencha touch styles and themes. Otherwise you can download a pdf file from this link which clearly describes about how to do it...
http://f.cl.ly/items/d9df79f57b67e6e876c6/SenchaTouchThemes.pdf
In it they are mentioning about scss file where you can specify the base-color, ie
$base-color: #4bb8f0 ;
$base-gradient: 'glossy';
Then run it ... you can see the toolbars and buttons created with the color and gradient you have mentioned.
I'm trying to create programatically an EnahncedGrid with a menu. I've got the grid to work, but I've been unable to use the menu. It just not shows up. The code is as follows:
<script>
sMenu = new dijit.Menu({});
sMenu.addChild(new dijit.MenuItem({
label: "Delete Record",
iconClass: "dijitEditorIcon dijitEditorIconCancel",
onClick : function(){
alert(1);
}
}));
sMenu.startup();
/**
* El grid propiamente dicho
*/
var grid = new dojox.grid.EnhancedGrid({
id: "grid_"+i,
query: {
idDocument: '*'
},
plugins: {
nestedSorting: true,
indirectSelection: true,
menus: {rowMenu:sMenu}
},
onRowDblClick: openFile,
structure: layout
})
</script>
Any idea what I'm doing wrong?
I haven't used this myself, but I have two possible suggestions:
First, make sure you're dojo.require-ing "dojox.grid.enhanced.plugins.Menu" and are only instantiating the widgets within a dojo.addOnLoad or dojo.ready.
If you've already done that, the second thing I'd suggest is giving your menu an id, and passing that id to the rowMenu property of the menus object (in other words, pass a string, not the widget itself). Although, the way you're doing it seems like it should work, judging from the code.
You can see a test page with working menus here: http://archive.dojotoolkit.org/nightly/dojotoolkit/dojox/grid/tests/enhanced/test_enhanced_grid_menus.html
