Found a couple of posts that came close to solving this. I'm loading a chart into a widget and it's not filling it, instead it's centered and extended past the widget - about only 1/3 of the pie chart shows for example.
I found the resize options for gridster and it gets me almost there... the same problem exists when I load the page, but when I resize the widget the chart fills it in perfectly.
I've tried aligning the chart, removing width and height settings, addeing resize and stop elements to gridsters..
var gridster = null;
$(document).ready(function () {
gridster = $(".gridster ul").gridster({
widget_base_dimensions: ['auto', 140],
autogenerate_stylesheet: true,
min_cols: 1,
max_cols: 6,
widget_margins: [5, 5],
resize: {
enabled: true,
resize: function (e, ui, $widget) {
Highcharts.charts[0].reflow(); // reflow the first chart...
},
stop: function(e, ui, $widget) {
Highcharts.charts[0].reflow(); // reflow the first chart...
}
}
}).data('gridster');
$('.gridster ul').css({'padding': '0'});
});
Highcharts.chart('container', {
chart: {
type: 'pie'
},
title: {
text: 'User data',
style: {"fontSize": "15px" , "color":"red"},
},
subtitle: {
text: 'Source: Click the slices to view categories.'
},
plotOptions: {
pie: {
showInLegend: false,
dataLabels: {
formatter: function(){
console.log(this);
if (this.percentage > 5)
return this.key + ': ' + this.y;
else
this.point.visible = false;
return '';
}
}
},
series: {
dataLabels: {
enabled: true,
}
}
},
tooltip: {
headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
when page loads the pie chart is sized to fit into the gridster widget.
Add one div wrapper around widget and add class which having height and width of that widget. It will render your highchart graph in that wrapper only.
<div class="size-1x1">
Render your graph code here
</div>
CSS:
.size-1x1 {
height:100px;
width: 120px;
}

I am using HighChart library to show Pie Chart on my page, I am keeping showTable always true to show every time.
The problem is whenever data binds to charts using JQuery Ajax post dynamically, i see proper data in chart but also it keeps adding new data table everytime at the bottom. E.g. First time there will be only one table, after another call there will be two tables added and so on. Why Hightcharts not updating the same table again or is there a way to kill any existing table.?
hc = Highcharts.chart(chartName, {
chart: {
type: 'pie',
options3d: {
enabled: false,
alpha: 45
},
style: {
color: '#575962'
}
},
title: {
text: title,
style: {
color: '#575962',
fontweight: '400'
}
},
subtitle: {
text: 'Current Month(Top 10)'
},
plotOptions: {
pie: {
innerSize: 100,
depth: 45,
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: false
},
showInLegend: true
}
},
credits: {
enabled: false
},
exporting: {
showTable: true
},
series: [{
name: 'Price',
data: [],
dataLabels: {
formatter: function () {
//const point = this.point;
//return '<span style="color: #575962;font-size:11px;font-weight: 400">' +
// point.name + ': $' + point.y + '</span>';
}
}
}]
});
Why Hightcharts not updating the same table again or is there a way to kill any existing table.?
I have achieved this by removing the series on each call and adding them again with new data. Hope this helps if anyone else looking and couldn't find any other answer.
//Removing Series
while (hc.series.length > 0) {
hc.series[0].remove(false);
}
//Adding new Series
hc.addSeries({
name: 'Price',
data: [],
dataLabels: {
formatter: function () {
const point = this.point;
return '<span style="color: #575962;font-size:11px;font-weight: 400">' +
point.name + ': $' + point.y + '</span>';
}
}
});
//Binding Series data
var res = result.Data.slice(0, 10);
res.forEach(function (element, index) {
hc.series[0].addPoint({
name: element.ResourceGroupName,
y: element.TotalMonthlyPrice,
});
});
I want to make some tooltips visible in my d3 map. The tooltips are column charts generated by Highcharts regarding the chosen city. The trick is that everything is displaying correctly (axis, labels ...) except that the columns are not visible!
Here my d3 code (only the relevant parts):
var tooltip = d3.select("body")
.append("div")
.attr("id","tooltip")
.style("position", "absolute")
.style("visibility", "hidden");
cities.on("mouseover", function(d, i) {
d3.select(this).style('fill', '#95a5a6');
tooltip.html(zoomCityComm(d))
return tooltip.style("visibility", "visible")})
.on("mousemove", function(d, i){
return tooltip.style("top", (d3.event.pageY - 130) + "px").style("left",(d3.event.pageX - 120) + "px");
})
}
The function zoomCityComm is HighCharts (example of data: [5,10]):
function zoomCityComm(d) {
chart = new Highcharts.Chart({
chart : {
renderTo: 'tooltip',
type: 'column',
width:200,
height:200,
plotBackgroundColor: '#FCFFC5',
zoomType: 'xy'
},
title: {
text: "TOTO"
},
legend: {
enabled: false
},
xAxis: {
categories: ['In','Out']
},
yAxis: {
title: {
text: 'Sum',
style: {
color: '#4572A7'
}
},
labels: {
style: {
color: '#4572A7'
}
},
},
series:[{color: '#4572A7',data: res}]
});
return document.getElementById("tooltip").innerHTML;
}
When the graph is displayed in a "normal" div within the document, it appears correctly.
Sorry if my explanations are not clear but ask me for some details if needed.
Thanks
Cyril
You're setting the HTML content of the div twice, as highcharts renders it itself. In your mouseover handler function, it is enough to do
zoomCityComm(d);
instead of
tooltip.html(zoomCityComm(d));
For the interested, here's what's happening. Setting the HTML of the tooltip div from the return value of the function captures the first animation frame that highchart uses to grow the bars. As it is the first frame, the height of the bars is still 0 -- that is, the bars are there, but not visible because they have essentially no height. Replacing the HTML of the div means that the animation won't work anymore, as the elements that would be animated have been replaced.
I'm trying to apply the new threshold/negativeColor features of Highcharts v3.0.2 to essentially the 'spline updating each second' example.
During the animation of the chart updating, I'm seeing weird artifacts in the series line - it looks like it's animating to a different set of control points.. and then it snaps back to the correct configuration when the animation (of the new data point coming in) is done.
Commenting out the threshold/negativeColor features makes this visual artifact go away.
Am I seeing a bug?
UPDATE: I'm posting the following code as an example, which is the stock highcharts demo (my local jquery is v1.10.2) with the threshold/color/negativeColor lines (first lines under series) added by me. This code seemingly misbehaves.

Indeed it looks like a bug, reported here. At this moment you can only disable animations.
Steps to reproduce.
We have a chart that display 4 series of data, and we have the corresponding legends with each series.
THe initial chart is loaded with 1 years worth of data.
We then remove all data-series from the chart by clicking on the 4 legends
We then change the Zoom level of the chart - e.g. going from a 6 month zoom, to a 3 month zoom. (NOTE: We change Zoom with no data-series being displayed).
We then re-enable the data-series by clicking on the legends.
The chart does not redraw correctly. To get the chart to redraw we have to reload the entire page.

JsFiddle Example
It looks like a bug, so I've reported it to our devs here: https://github.com/highslide-software/highcharts.com/issues/1568
A simple workaround :
After some trial and error, I found out that if you do not disable the navigator, the above bug is not exhibited. (Navigator is enabled by default.)
Comment the line as shown below:
navigator: {
//enabled: false
}
Js Fiddle : http://jsfiddle.net/msjaiswal/FDXBu/1/
Certainly this is a bug in Highcharts but we can live with this above simple workaround.
This issue has been resolved in version 1.3.2 of HighStock.
I am new to highchart and am using it to render bar chart on my webpage. But the chart is not getting displayed while printing. Only the X and Y axis is printing with values but not the bars on it.
I am using IE8. The bar chart is visible(on print) in IE8 mode but its not visible in IE8 Compatible mode. I need to make it work on IE default mode i.e. IE8 compat. mode.
Can anyone help me in this issue.
I am adding a code chunk of my js function where I am printing my highchart in a lightbox window.
var chart = new Highcharts.Chart({
chart: {
renderTo: 'containerDivID',
type: 'column'
},
title: {
text: ''
},
xAxis: {
categories: xDataValues
},
yAxis: {
min: 0,
title: {
text: ''
}
},
tooltip: {
formatter: function() {
return ''+
this.x +': '+ this.y +' kr';
}
},
plotOptions: {
column: {
stacking: 'normal',
borderWidth: 1,
dataLabels: {
enabled: false,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
}
}
}
,
yAxis: {
labels: {
formatter: function() {
return this.value;
}
},
title:{
text: ''
}
},
series: [
{
name: 'YAxis',
color: '#37789F',
data: yDataValues
}
],
credits:{
enabled: false
}
});
In this lightbox I have a print button on pressing this button I am calling window.print() to print the page. On my print page I can see the y and x axis and there data but cannot see my bar charts. But If I change IE8 mode from Compatible to IE8 standard mode then I can see my chart on printing.

Andi
For me I didn't use the print() function to print the chart as I need to print extra data with the chart; As my chart is part of a report.
kindly find the custom print function I wrote:
function printReport() {
w = window.open();
var svg = myChart.getSVG();
//clone the div you want to print which contains your chart
var toprint = $('#bs-results') .clone();
//replace the chart with the svg
toprint.find('#graph_div').html(svg);
//right the output to print it
w.document.write(toprint.html());
w.print();
w.close();
}
