Group Kendo ui chart category axis Date label rounding - charts
On my below Kendo UI chart, I always wanted to show exactly 5 category (X) axis labels (which is achieved).
I have 2 questions (refer attached image for more details),
1) These labels have to be properly rounded in near by hour or 30 minute
2) Tooltip has to be formatted in dd.MM.yy HH:tt
Data for this chart is received dynamically. I cannot use the category axis type as 'Date' as I wanted to show all data points on the graph.
My sample code is available below,

For the Tooltip you can use the sharedTemplate to format the category as desired:
sharedTemplate: '<div> #= kendo.toString(new Date(category), "dd.MM.yy HH:mm") # </div># for (var i = 0; i < points.length; i++) { # <div>#: points[i].series.name# : #: points[i].value #</div># } #'
For the label template, add your own rounding logic for the timestamp, e.g.:
labels: {
template: function(e){
var val =new Date(e.value);
var mins = val.getMinutes();
if (mins < 15 ) {
val.setMinutes(0);
} else if (mins < 45) {
val.setMinutes(30);
} else {
val.setHours(val.getHours() + 1);
val.setMinutes(0);
}
var label = kendo.toString(val, "dd.MM.yy HH:mm");
return label.split(" ").join("\n");
}
}

How to force a close spider after adding a new group of markers?
I use the following libraries:
leaflet.js
leaflet.markercluster.js
leaflet.subgroup.js
and my own script.
I have 3 marker types, all in a different subgroups. 11 Markers are on the same location. When I open the cluster the spider is shown, on unchecking 1 marker type, the spider is closed and the counter shows the right value. When I reopen the cluster, modified spider is shown.
Checking the marker type does not put the extra spider-marker on the screen, but also does not close the spider.
How can I force the spider to be closed?

Pasted the code provided in your question into Plunker for a live demo: https://plnkr.co/edit/ZzKRs5NnrJeWfBKWOA3R?p=preview
Hum looks like you are hitting a bug in Leaflet.markercluster.
When you tick in your SubGroup in the Layers Control, the former will use the parent group's (mcg in your case) addLayers method if it exists.
While MCG addLayer (single) correctly unspiderfies, this step is missing in addLayers (batch).
Reproducing the bug with a more simple example: https://plnkr.co/edit/G4GAjax5fi3LUqJRLLPN?p=preview (without Leaflet.FeatureGroup.SubGroup plugin)
Then it should be quite simple to fix this bug: simply unspiderfy, similarly to how it is done in addLayer:
if (this._map && this._unspiderfy) {
this._unspiderfy();
}

Highcharts - How to add background in bar series? And how to print page without lose quality?
I need your help, i try use "pattern" in Highcharts to use background in bars, but the images don't fill the space that i wanna.
Bar Chart Example
I wanna know, how i do to leave the image with -90° than the way that is? And how i do to leave the image with height 100% and width 25%?
And beyond that i wanna of know, how i print the screen without lose the quality in image, because when i press "ctrl+p" i see all all blurred.
Print blurred

1. PATTERN FILL ADJUSTMENT
Refer to this live working example: http://jsfiddle.net/kkulig/opa73k8L/
Full code:
var redrawEnabled = true,
ctr = 0;
$('#container').highcharts({
chart: {
events: {
render: function() {
if (redrawEnabled) {
redrawEnabled = false;
var chart = this,
renderer = chart.renderer;
chart.series[0].points.forEach(function(p) {
var widthRatio = p.shapeArgs.width / p.shapeArgs.height,
id = 'pattern-' + p.index + '-' + ctr;
var pattern = renderer.createElement('pattern').add(renderer.defs).attr({
width: 1,
height: widthRatio,
id: id,
patternContentUnits: 'objectBoundingBox'
});
renderer.image('http://emoticons.topfriends.biz/favicon.png', 0, 0, 1, widthRatio).attr({
}).add(pattern);
p.update({
color: 'url(#' + id + ')'
}, false);
});
ctr++;
chart.redraw();
redrawEnabled = true;
}
}
}
},
series: [{
type: 'bar',
borderWidth: 1,
borderColor: '#000000',
data: [10, 29.9, 71.5]
}]
});
In the redraw event I iterate all the points, create a separate pattern for every point based on its width/height ratio, apply pattern and redraw the chart.
On every redraw new set of patters are created which is not an elegant solution (old ones should be replaced instead). ctr variable is used to create unique name for each pattern.
redrawEnabled serves to prevent infinite recursive loop because chart.redraw() also calls the render event.
In my opinion the easiest way to have the rotated image is to simply provide the already rotated one.

It seems to be a bug reported here: https://github.com/highcharts/pattern-fill/issues/20
Flot charts. Adapt visible chart to the yaxis
Can I adapt the visble data in the chart to the Yaxis when I drag the chart across the x axis?
In the actual example I can drag the chart across the X Axis, but the chart doesnt adapted to the Y Axes. The y min, and the y max options are the same and calculate for all the chart.

Take a look at Flot charts - changing the y axis on the fly You could get the min and max values and set the plot like that: plot.getOptions().yaxes[0].min = 0; plot.getOptions().yaxes[0].max = yourMAXNOW;

As per the above code there is space between col 2 which gives error "col 2" is not a valid ID.. Here is the bin. But when I replace col 2 with col2 it works fine. But in real time I get spaces in data so how to fix it so that it would work with spaces also.
I would guess, that the error comes from the invalid ID of the Column object: id : sColumnId, (the first line after return new sap.ui.table.Column({) and not from the binding.
Like Mark said in his comment Element IDs cannot contain spaces. But the ID is not visible to the User and you can just replace the spaces of the Column.id while assigning or you can skip the id assignment at all to get automaticaly generated ids.
A client who demands spaces in their ID's I would 1) definitely steer clear from, and if that's not possible, 2) educate them that their "requirement" is utter [...]
Nevertheless, I would simply replace the spaces with underscores (it's really simple Javascript):
airsideTableDataOriginal.forEach(function(obj) {
obj.columnId = obj.columnId.replace(/ /g,"_");
});
aColumnData.forEach(function(obj) {
obj.columnId = obj.columnId.replace(/ /g,"_");
});
aData.forEach(function(obj) {
for (var property in obj) {
if (obj.hasOwnProperty(property)) {
if (~property.indexOf(" ")) {
var newProperty = property.replace(/ /g,"_");
obj[newProperty] = obj[property];
delete obj[property];
}
}
}
});
Sencha Ext JS 4 trouble getting drag&drop to work properly
I'm attempting to learn extjs 4 and I've been struggling with drag and drop for the past couple of days. I've attempted to build a simple application with a viewport and 1 panel. I've set the panel to be draggable: true and the viewport to be a dropzone. When I try and drag the panel around the viewport it jumps erratically.
This is a short video clip of the behavior:
http://youtu.be/6WRf5j_CAR0
These are my two files:
app.js
Ext.Loader.setConfig({
enabled: true
});
Ext.application({
name: 'CS',
appFolder: 'ccms/app',
autoCreateViewport: true,
controllers: [
// 'TestCreator',
// 'Primary',
// 'Manager'
],
launch: function(){
var viewport = Ext.ComponentQuery.query('viewport');
if(viewport.length > 0)
viewport[0].add([{
xtype: 'panel',
width: 300,
height: 300,
draggable: true
}]);
}
});
Viewport.js
Ext.define('CS.view.Viewport', {
extend: 'Ext.container.Viewport',
// layout: 'fit',
listeners: {
render: function(sender){
console.log(sender);
sender.dropZone = new Ext.dd.DropZone(sender.container, {
getTargetFromEvent: function(e) {
console.log('getTargetFromEvent');
var temp = {
x: e.getX() - this.DDMInstance.deltaX,
y: e.getY() - this.DDMInstance.deltaY
};
console.log(temp);
return temp;
},
// On entry into a target node, highlight that node.
onNodeEnter : function(target, dd, e, data){
// Ext.fly(target).addCls('my-row-highlight-class');
},
// On exit from a target node, unhighlight that node.
onNodeOut : function(target, dd, e, data){
// Ext.fly(target).removeCls('my-row-highlight-class');
},
onNodeOver : function(target, dd, e, data){
return Ext.dd.DropZone.prototype.dropAllowed;
},
onNodeDrop : function(target, dd, e, data){
console.log('onNodeDrop');
data.panel.setPosition(target.x, target.y, true);
return true;
}
});
}
}
})

Can anyone tell me what is going on?
I've tried this with Ext JS 4.07 and the 4.1 Beta, same results
Make sure to Change your Panel to DOM element though Panel is a component
listener: {
render: function (panel) {
var PanelEl = Ext.get(panel.id);
sender.dropZone = new Ext.dd.DropZone(PanelEl, {
//...
}
}
