Im using Stacked area chart of nvd3-angularjs
This is my html
<div ng-controller="Eth2GraphController">
<nvd3-stacked-area-chart
data="GraphData"
noData="No Data For You!"
id="eth2Graphs"
showXAxis="true"
showYAxis="true"
showLegend="true"
interactive="true"
tooltips="true"
objectEquality="true"
margin="{left:100,right:100}"
useInteractiveGuideline="true"
tooltipcontent="toolTipContentFunction()"
xAxisTickFormat="xAxisTickFormatFunction()"
yAxisTickFormat="yAxisTickFormatFunction()"
color="colorFunction()"
legendColor="colorFunction()"
>
<svg></svg>
</nvd3-stacked-area-chart>
</div>
Now, I have a function that should format the tooltipcontent, but its not working. Maybe it has something to do with the useInteractiveGuideline attribute. I used the same tooltipcontent function to edit the tooltip of my other charts, its working on those charts the only difference is that those chart dont use useInteractiveGuideline.
$scope.toolTipContentFunction = function() {
return function(key, x, y, e, graph) {
return '<h3>' + x + '</h3>' +
'<p>' + key + ' ' + y + '</p>';
}
};
I want x to be in the center, and other formatting for the data. How would I do that? Am I using the correct attribute that would format the tooltip?
Change tooltipcontent="toolTipContentFunction()" to:
tooltipContent="toolTipContentFunction"
useInteractiveGuideline must be set to false for the tooltipContent to work. I believe it is because useInteractiveGuideline uses it's own popup.

I have a null value in my HighCharts line chart. I set connectNulls: true so that the line does not disconnect when the data is null. However I cannot hover over that null value. When I try to, it automatically jumps to the nearest non-null point.
Fiddle: https://jsfiddle.net/wmoxLy4r/2/
What I am trying to do is to:
1/ Allow hovering over null values
2/ When hovering over null values, I would like to show the value of the closest non-null value to the left. In this case it would show 129.2.
I thought about imputing the null value with the closest non-null value to its left but then the plot will be flat at that section due to 2 periods with the same values. I want the plot to looks like it does right now. Appreciate any help
You can preprocess your data and calculate the middle points. A null point doesn't have a marker and it's not possible to show a tooltip for it.
const data = [...];
const processedData = data.map((dataEl, index) => {
if (!dataEl) {
return {
y: (data[index - 1] + data[index + 1]) / 2,
isCalculatedValue: true,
marker: {
fillColor: 'red',
radius: 1
}
}
}
return dataEl;
});
By using tooltip.formatter function, you can show the previous point value in a tooltip.
tooltip: {
formatter: function(tooltip) {
let point = this.point;
if (point.isCalculatedValue) {
point = this.series.points[point.index - 1];
}
return "<span style='font-size: 10px'>" + point.category + "</span><br/>" +
"<span style='color:" + point.series.color +
"'>●</span> Line series: <b>" + point.y + "</b><br/>";
}
}

I am attempting to customize my Highcharts legend to html with in line style tag in order to change the color using this.color
I am using
labelFormatter: function () {
return "Total amount of <b style='" + this.color + ">" + this.name + " Percentage"
}
in attempt to accomplish this. I would like the legend of graph to display "Total amount of LOW Percentage" I am able to accomplish this but I am now trying to add styling to "LOW", "MEDIUM" or "HIGH" which is coming from this.name; I would like to make that color the same color that it is in the graph such as :
LOW = Green,
MEDIUM = Orange
HIGH = RED
I attempted to accomplish this by using this.color but it did not have any affect on my legend.
Here is a jsfiddle with my code: https://jsfiddle.net/uyr2tb7n/3/
The returned string should look like this:
legend: {
...,
labelFormatter: function() {
return "Total amount of <span style='color:" + this.color + "'>" + this.name + "</span> Percentage"
}
}

I created a sunburst chart with highcharts. I set the config object given to Highcharts.chart('type', config) in python. I want to have one different tooltip for each level of the sunburst chart.
I can do a big js function that search the level of the point in my data then give the level to the tooltip formatter to display the specific data, but that is not suitable I think.
Is there any highcharts function to get the point's level or to define the tooltip in series.levels[]?
You could get this based upon the slice's level property. You can do something like:
tooltip: {
formatter: function () {
console.log(this); // see what each slice's properties are
if (this.point.node.level == 4) {
return 'Population of <b>' + this.point.options.name +
'</b> is <b>' + this.point.options.value + '</b>';
} else {
return 'Level <b>' + this.point.node.level + '</b> has no tooltip';
}
}
}
Example jsFiddle
Tank you for your answer wergled. In fact what help me is the console.log(this)! I don't know why but this refers directly to the point in my code. And since I code in python, I have to format a js function into a python string, this is quite difficult.
So I ended with something like:
config['tooltip']['pointFormatter'] = (
"function(){"
"var level = this.node.level;"
"return"
f" {myValues}[level] + '<span style=\"text-transform: uppercase;font-weight:bold\">{myPythonVar}:</span> '"
f"+ {myJsFormatter}.call(this) + '<br>'"
"}"
)
It mixes python and js, it hard to read but needed in my case.
Is there a more efficient way for displaying a tool tip once a cell is hovered? Using the structure attribute to format the datagrid, is there a way to use formatter to display a dijit toolTip rather than using the html title attribute.
Here is the column in which the toolTip is displaying.
var subscriberGridLayout = [
{
name: " ",
field: "ExpirationDate",
formatter: function(value){
if(value){
expDate = formatDateIE(value);
return toolTip();
}
else
return " ";
},
styles: "text-align: center;",
width: "30px"
},
Here is the function that displays a tooltip icon through the image tag but instead of a dijit toolTip it simply uses html's title to display a popup.
function toolTip(){
src = "'/Subscriber/resources/images/icons/icon_error.gif'/>";
if(dojo.date.difference(today, expDate) <= 0 ){
message = "Credential expired.";
return "<img title='"+ message + "' src=" + src + "";
} else if(dojo.date.difference(today, expDate) <= 60) {
message = "This Subscriber will expire in " + dojo.date.difference(today, expDate) + " days."
+ "
To prevent an interruption in the Subscriber’s access, please sumbit a request to " +
"renew the Subscriber within 30 days of the expiration date.";
return "<img title='"+ message + "' src=" + src + "";
} else {
return " ";
}
}
I would do something like:
new Tooltip({
connectId: grid.domNode,
selector: "td",
getContent: function(matchedNode){
return matchedNode.innerText
}
});
With grid.domNode you can get the generated DOM of your widget. A grid generates a table-structure, so you can get the cells by using the selector and getContent properties.
I must say it's not really the correct way to do it because now you're playing with the internal structure of the Dojo widget. If they once decide not to use a table as DOM structure your code won't work.
But I don't think there is a better way to achieve this, in the end you will always have to translate the Dojo cell to a DOM node (because tooltips are DOM based). You can of course connect a tooltip to each cell, but I tried that before and it was a little buggy (sometimes the tooltip didn't pop up).
I also made a JSFiddle to show you a working example.
I am creating a JQuery Mobile application that has a listview. I am populating that listview with the results of a web service. Because of this, the items in the list view are being populated as shown here:
$.each(results, function (i, result) {
var s = "<li><h2 style='padding-left:40px;'>" + result.title + "</h2><p style='padding-left:40px;'>";
s += result.subTitle;
s += "</p><span class='ul-li-count'>" + result.count + "</span></li>";
$("#resultListView").append(s);
});
$("#resultListView").listview("refresh");
My listview is being populated correctly. The value for the count bubble is showing. However, the UI does not render the bubble. Is there a way to dynamically build a result set with count bubbles in a list view? If so, how?
Thank you!
Your way should work. The only thing I can think of is that the HTML is not valid.
Anyway, I created a simple version to show that it's possible. http://jsfiddle.net/kiliman/HDUqp/
Basically, just build up the HTML for <li/> and append to the list, then call .listview('refresh')
$('#page1').bind('pageinit', function(e, data) {
var n = 0;
$('#addResult').click(function(e) {
var $list = $('#resultListView');
n++;
$('<li/>')
.append($('<h2>', { text: 'Title ' + n }))
.append($('<p>', { text: 'SubTitle ' + n }))
.append($('<span />', { text: n, class: 'ui-li-count'}))
.appendTo($list);
$list.listview('refresh');
});
});
