Fairly straightforward, but I have a single bar on a barchart that I want to show by itself. I've hidden the axes and their ticks, but there is still all of that space there on the left and top//bottom of chart from the axes and the legend I am presuming.
Is there a way to remove this space without just putting negative margins on the element?
I've tried working with negative padding, but that doesn't work on the top and bottom of the chart.
I made a quick CodeSandbox to show my actual component
Any tips would be greatly appreciated!
Cheers!

This is because you set barThickness to 20 in your datasets. If you remove this it will show as you want:

I have a datatable and i have print button and pdf button.
I can change font size when print page but i can't change font size while exporting pdf file.
{
extend: 'pdfHtml5',
text: 'Save PDF',
exportOptions: {
modifier: {
page: 'current'
}
},
header: true,
title: 'My Table Title',
orientation: 'landscape'
},
{
extend: 'print',
text: 'Print',
customize: function ( win ) {
$(win.document.body)
.css( 'font-size', '15pt' )
$(win.document.body).find( 'table' )
.addClass( 'compact' )
.css( 'font-size', '8pt' );
},
header: false,
title: '',
orientation: 'landscape'
},
can you help me?
If you look at the src of html5.js, it creates a default object literal doc holding default settings :
var doc = {
pageSize: config.pageSize,
pageOrientation: config.orientation,
content: [
{
table: {
headerRows: 1,
body: rows
},
layout: 'noBorders'
}
],
styles: {
tableHeader: {
bold: true,
fontSize: 11,
color: 'white',
fillColor: '#2d4154',
alignment: 'center'
},
tableBodyEven: {},
tableBodyOdd: {
fillColor: '#f3f3f3'
},
tableFooter: {
bold: true,
fontSize: 11,
color: 'white',
fillColor: '#2d4154'
},
title: {
alignment: 'center',
fontSize: 15
},
message: {}
},
defaultStyle: {
fontSize: 10
}
};
You can use the customize callback to change those default settings :
{
extend: 'pdfHtml5',
text: 'Save PDF',
exportOptions: {
modifier: {
page: 'current'
}
},
header: true,
title: 'My Table Title',
orientation: 'landscape',
customize: function(doc) {
doc.defaultStyle.fontSize = 16; //<-- set fontsize to 16 instead of 10
}
},
Changing the header font size:
doc.styles.tableHeader.fontSize = 30
https://jsfiddle.net/2nwqa2jk/12/
Change alignment, set center to all headers, all columns all footers :
doc.defaultStyle.alignment = 'center'

I have a quite a complicated layout for my application, using borders, vbox's and hbox's which all seem to fit quite well except for one annoyance. The bottom of the grid in the southern region is not behaving. I want the grid to take up the height of the panel when the browser is above minHeight/maximized but at the moment it look like this:
And when the browser is shrunk (but not below min size) it looks like this and I am unable to get to the bottom of the grid scrollbar :(
You can see the scrollbar cut of (probable min height on the viewport/grid issue) but not sure how to fix this can someone spot what I need to do resolve these two issues? Code below:

Thank you kindly

I'm referring to lines 87-97 of the syntax highlighted link you posted.
resize: function(){
var programGrid = Ext.getCmp('programList');
if(this.getHeight() < this.minHeight){
console.log("Height: ", this.getHeight());
console.log("minHeight: ", this.minHeight);
console.log("Grid old height: ", programGrid.height);
programGrid.height = (this.minHeight - programGrid.height)-18;
this.setSize(this.getWidth(), this.getHeight());
console.log("Grid new height: ", programGrid.height);
} else {
programGrid.height = 380;
}
}
This is the resize handler for the viewport, so every time the browser is resized, this funciton will explicitly set the grid height. Not sure what the purpose of this code is but it looks like it could be the issue. Generally you shouldn't need code like this - everything should fit together if you have the layouts set up right, and then you can use minHeight/maxHeight for the grid if you want. What happens if you just take this code out?
I think you need to remove the resize event handler completely. It looks like you're trying to create a 'vbox' layout on your center panel, but you're using 'type: vbox'. Try using this:
layout: {
type: 'vbox'
align : 'stretch',
pack : 'start',
}
This was taken from the ExtJS examples (http://docs.sencha.com/ext-js/4-2/extjs-build/examples/layout-browser/layout-browser.html). Then you can just add a 'flex' to your child containers instead of a minheight.
Ext.onReady(function(){
Ext.create('Ext.panel.Panel',{
title:'MAin Panel',
renderTo:Ext.getBody(),
height:600,
width:600,
bodyStyle: {
background: 'yellow',
position:'absolute ',
'z-index': -1
},
items:[
{
xtype: Ext.create('Ext.window.Window',{
height : 500,
width : 500,
id:'abc',
items : [
{
xtype : 'button',
text : 'Open',
handler : function(){
/* w2.showAt(450,300);
w1.disable(); */
}
},
{
xtype:'panel',
title:'Inner Panel',
height:200,
width:200,
style:{
position:'absolute ',
'z-index': 2
}
}
],
bodyStyle:{
background: '#000000',
opacity: 0.7,
},
style:{
position:'absolute',
'z-index': 1
}
})
}
]
});
Ext.getCmp('abc').show();
w1.setTitle('Window 1');
w1.show();
});
I have the above code, and I want that "Inner Panel" should come over window "abc", and the opacity attribute should not apply on "Inner Panel". Child components of window "abc" is also getting the opcaity. I have tried the style:{ position:'absolute', 'z-index': 1}, same code is working html,but not in extjs.
I suggest you to use ZIndexManager.
First, register all of your containers and then use bringToFront method to show the container you want.
var colors = ['url(#v-1)',
'url(#v-2)',
'url(#v-3)',
'url(#v-4)',
'url(#v-5)'];
var baseColor = '#eee';
Ext.define('Ext.chart.theme.Fancy', {
extend: 'Ext.chart.theme.Base',

this.callParent([Ext.apply({

fill: baseColor,

},
axisLabelLeft: {

},
axisLabelBottom: {

I am selecting the first column, and i don't click it, just with the mouse over it. The higlight color is a variante of blue. But in the code i use itemmousedown, and i don't understand why the bar changed color only by passing by the mouse? how can i put it only highlight only in mouse click?
What about highlight: false?
If you just want the bar to be highlighted by a click, you should add a listener which highlights it on clicking the bar.
