This is how I remove data points upon clicking a datapoint:
item.series.data[item.dataIndex].shift()
item.series.data[item.dataIndex].shift()
Whats the code to delete the entire series that the data point belongs to?
I'm guessing you are doing this from a plotclick handler:
$("#placeholder").bind("plotclick", function (event, pos, item) {
if (item){
var someData = plot.getData(); //get the series array
someData.splice(item.seriesIndex,1); //remove the index of the one clicked
plot.setData(someData); //set the data
plot.setupGrid();
plot.draw(); //redraw
}
});
Working fiddle here.
EDITS FOR COMMENTS
Updated fiddle here which deletes from multiple graphs based on series name instead of index position.
$(".chart").bind("plotclick", function (event, pos, item) {
if (item){
var label = item.series.label;
$([plot1, plot2]).each(function(i,plotObj){
var someData = plotObj.getData();
for (var i=0; i<someData.length; i++){
if (someData[i].label == label){
someData.splice(i,1);
}
}
plotObj.setData(someData);
plotObj.setupGrid();
plotObj.draw();
});
}
});

I need to prevent/disable nested lists in text editor implemented in Angular. So far i wrote a hack that undos a nested list when created by the user. But if the user creates a normal list and presses the tab-key the list is shown as nested for a few milliseconds until my hack sets in back to a normal list. I need something like event.preventDefault() or stopPropagation() on tab-event keydown but unfortunately that event is not tracked for some reason. Also the froala settings with tabSpaces: falseis not showing any difference when it comes to nested list...in summary i want is: if the user creates a list and presses the tab-key that nothing happens, not even for a millisecond. Has anyone an idea about that?
Froala’s support told us, there’s no built-in way to suppress nested list creation. They result from TAB key getting hit with the caret on a list item. However we found a way to get around this using MutationObserver
Basically we move the now nested list item to his former sibling and remove the newly created list. Finally we take care of the caret position.
var observer = new MutationObserver(mutationObserverCallback);
observer.observe(editorNode, {
childList: true,
subtree: true
});
var mutationObserverCallback = function (mutationList) {
var setCaret = function (ele) {
if (ele.nextSibling) {
ele = ele.nextSibling;
}
var range = document.createRange();
var sel = window.getSelection();
range.setStart(ele, 0);
range.collapse(true);
sel.removeAllRanges();
sel.addRange(range);
};
var handleAddedListNode = function (listNode) {
if (! listNode.parentNode) {
return;
}
var parentListItem = listNode.parentNode.closest('li');
if (!parentListItem) {
return;
}
var idx = listNode.children.length - 1;
while (idx >= 0) {
var childNode = listNode.children[idx];
if (parentListItem.nextSibling) {
parentListItem.parentNode.insertBefore(childNode, parentListItem.nextSibling);
} else {
parentListItem.parentNode.appendChild(childNode);
}
--idx;
}
setCaret(parentListItem);
listNode.parentNode.removeChild(listNode);
};
mutationList.forEach(function (mutation) {
var addedNodes = mutation.addedNodes;
if (!addedNodes.length) {
return;
}
for (var i = 0; i < addedNodes.length; i++) {
var currentNode = addedNodes[i];
switch (currentNode.nodeName.toLowerCase()) {
case 'ol':
case 'ul':
handleAddedListNode(currentNode);
break;
// more optimizations
}
}
})
};
I want to remove elements based on ID with double click
Tried this but it is not working:
paper.on('cell:pointerdblclick', function (cellView,cell)
{
selectedId = cellView.model.id;
selected = cellView.model;
$.each(cellsAdded, function(index, value)
{
if(selectedId !== cellsAdded[index])
{
selected.remove();
}
});
});
These are the cells in the graph:
var cellsAdded = graph.addCells([sidebar, rect, circle1, circle2, circle3, rectGroup0, diamond]);
All of the above cells have ids and I dont want to remove them, I only want to remove other elements which are not part of the above
I have a geojson file which I'm getting from this website which somehow contains corrupt data, with a coordinate value = null.
http://measuringamsterdam.nl/datalist/kijk/
And I'm using it in my code like this:
//Retrieve all data and add to map
$.each(datalistObject['idlist'], function(key, value) {
$.getJSON('http://measuringamsterdam.nl/datalist/kijk/' + value['id'], function(data) {
textbox = value['name'];
var dataid = L.geoJson([data], {
style: function (feature) {
return feature.properties && feature.properties.style;
},
onEachFeature: onEachFeature,
pointToLayer: function (feature, latlng) {
return L.marker(latlng, {
icon: value['icon']
});
}
}).addTo(jsonGroup);
console.log(jsonGroup);
},function(xhr) { console.error(xhr); });
});
Now somehow I need to filter out the features/objects where the coordinates have a null value.
I really need to filter the data that point in my code since I need the + value['id'] part in the getJSON code.
Ane ideas?
Using the following code you will generate a new array. Which will include only the filtered data.
var newArray = data.filter(function (el) {
return el.value != 'null';
});
You can also apply multiple filters, for example:
return el.value_a != 'null' && el.value_b > 100;
Hopefully this will work!
Was wondering if there is a plug-in already available for FLOT chart legend to be interactive like in highcharts
Providing the example out here
http://jsfiddle.net/yohanrobert/T3Dpf/1/
However, in a turn of event I tried my hand on mouseover event through jquery
$(".legendLabel").mouseover(function(){
// Unhighlight all points
console.log($(this))
plot.unhighlight();
// The X value to highlight
var value = parseInt($(this).context.innerText.replace('Series ',''))-1;
// Retrieve the data the plot is currently using
var data = plot.getData();
// Iterate over each series and all points
for (var s=0; s<data.length; s++) {
var series = data[s];
if(s==value){
for (var p=0; p<series.data.length; p++) {
plot.highlight(s, p);
}
}
}
});
Can anyone help me achieve the interactivity like in the example?
Extended togglePlot function for different plot types (we save the original plot type in the hidden property):
togglePlot = function (seriesIdx) {
var plotTypes = ['lines', 'points', 'bars'];
var someData = somePlot.getData();
var series = someData[seriesIdx];
$.each(plotTypes, function (index, plotType) {
if (series[plotType]) {
if (series[plotType].show) {
series[plotType].show = false;
series[plotType].hidden = true;
}
else if (series[plotType].hidden) {
series[plotType].show = true;
series[plotType].hidden = false;
}
}
});
somePlot.setData(someData);
somePlot.draw();
}
For highlighting a data series like in highcharts add a highlightPlot function like this (here only for line series):
highlightPlot = function (seriesIdx) {
var someData = somePlot.getData();
$.each(someData, function (index, series) {
someData[index].lines.lineWidth = (index == seriesIdx ? 4 : 2);
});
somePlot.setData(someData);
somePlot.draw();
}
I also changed the inline event handlers to jQuery event handling to make it cleaner:
$(document).on({
click: function () {
togglePlot($(this).data('index'));
return false;
},
mouseover: function () {
highlightPlot($(this).data('index'));
},
mouseout: function () {
highlightPlot(-1);
},
}, 'a.legend');
See this updated fiddle for the full example.

Hi, I am relatively new to flash and action script as well and I am having a problem getting the sprite to be removed after another is called. I am making emission spectrum's of 3 elements by dynamically generating the mask over a picture on the stage. Everything works perfectly fine with the code I have right now except the sprites stack on top of each other and I end up with bold lines all over my picture instead of a new set of lines each time i press a button.
I have tried using try/catch to remove the sprites and I have also rearranged the entire code from what is seen here to make 3 seperate entities (hoping I could remove them if they were seperate variables) instead of 2 functions that handle the whole process. I have tried everything to the extent of my knowledge (which is pretty minimal # this point) any suggestions?
Thanks ahead of time!
My AS3 knowledge is rather rudimentary right now but I think two things may help you.
You could use removeChild before recreating the Sprite. Alternatively, just reuse the Sprite.
Try to add this[spriteName].graphics.clear(); to reset the sprite and start redrawing.
function generateMask_Emission (dataArray : Array) : void {
var spriteName:String = "Mask"+index;
trace(spriteName);
// Don't recreate if sprite object already created
if (this[spriteName] == null)
{
this[spriteName] = new Sprite();
// Only need to add sprite to display object once
addChild(this[spriteName]);
}
for (var i:int= 0; i < dataArray.length; i+=2)
{
this[spriteName].graphics.clear();
this[spriteName].graphics.beginFill(0x000000, dataArray[i+1]);
this[spriteName].graphics.drawRect(dataArray[i],constY,constW, constH);
this[spriteName].graphics.endFill();
}
index++;
}
Just in case anyone was curious or having a similar problem. Extremely simple fix but here is what I did.
Also should mention that I don't think that the graphics.clear function actually fixed the problem (though I didn't have the sprite being cleared properly before), but I believe the problem lies in the beginning of the onloaded function where 3 of those variables used to be outside of the function.

var constY = 291; //this value represets the Y value of the bottom of the background spectrum image
var constW = 2; //this value represents the width of every emission line
var constH = 40; //this value represents the height of every emission line
//Create Button Labels
hydrogenBtn.label = "Hydrogen";
heliumBtn.label = "Helium";
lithiumBtn.label = "Lithium";
//These listen for the buttons to be clicked to begin loading in the data
hydrogenBtn.addEventListener (MouseEvent.CLICK, loadHydrogen);
heliumBtn.addEventListener (MouseEvent.CLICK, loadHelium);
