I'm trying to add images in chart using Highcharts.I doubt whether highcharts support images .i want to import image in empty content.Any help would be appreciated.Thank you in advance.
Highcharts.chart('container', {
chart: {
type: 'bubble',
plotBorderWidth: 1,
zoomType: 'xy'
},
title: {
text: 'No Date Availavle'
},
});

Here's an updated jsfiddle, you just have to add
renderer.image('https://www.highcharts.com/samples/graphics/sun.png', 100, 100, 30, 30)
.add();
To your chart, put the url, x position, y position and height, width as parameters.

In jqplot, why is the auto scaling on bar charts so very different from on line charts?
Using the exact same data, I get these two plots:
The options I use for the two plots are:
var bar_options = {
axesDefaults: { labelRenderer: $.jqplot.CanvasAxisLabelRenderer },
seriesDefaults: { renderer: $.jqplot.BarRenderer, rendererOptions: { highlightMouseOver:false, barMargin:5, shadowOffset:1 } },
axes: { xaxis: { renderer: $.jqplot.CategoryAxisRenderer }, yaxis: { tickOptions:{show:false} } },
};
and
var line_options = {
axesDefaults: { labelRenderer: $.jqplot.CanvasAxisLabelRenderer },
seriesDefaults: { rendererOptions: { smooth: true } },
axes: { xaxis: { min:1, max:30, tickInterval:1, pad:0 }, yaxis: { tickOptions:{show:false} } },
};
The line plot looks really good, but the bar chart is next to useless with the scaling shown.
Why is the default scaling so different between the two plots, and how can I get the scaling on the bar plot to be the same as the line graph?
EDIT:
I have created a simpler example, with data as follows:
[38.23, 39.33, 41.67, 40.21, 45.01, 44.47, 37.04]
And the resulting graph shown is this:
Adding a y-axis scale, shows that the data is starting from 0.
I changed my plot code to this...
var home_bar_options = {
axesDefaults: { labelRenderer: $.jqplot.CanvasAxisLabelRenderer },
seriesDefaults: { renderer: $.jqplot.BarRenderer, rendererOptions: { highlightMouseOver:false, barMargin:5, shadowOffset:1 } },
axes: { xaxis: { renderer: $.jqplot.CategoryAxisRenderer }, yaxis: { min:30, max:50 } }
};
But the plot doesn't change, and completely ignores the 'min' and 'max' values that I have entered for the y-axis scale.
Why is this?
I have not found any 'proper' way to move the axis on the bar chart, but I have managed to find a workaround.
My page is in PHP, and the data is coming from a mysql database.
So, after I have the data, and before I draw the bar chart plot, I get the minimum data value, and subtract that value from all my data!
So if my data is
35, 38, 36, 42, 40
I subtract 35 from all data, giving a new data set of
0, 3, 1, 7, 5
The bar chart will then plot this in a much better looking way!
Because I don't need to see actual data numbers, just the trend, this works ok for me - but wouldn't work if you needed a y-axis with a scale.
If anyone has a 'proper' way to properly adjust the bar plot y-axis away from zero, then I would be very happy to hear it!
But, for now, my workaround will suffice!
How can I set to always show the labels in my sunburst chart? I have this plunker like in the demo: http://plnkr.co/edit/emCcNv?p=preview
$scope.options = {
chart: {
type: "sunburstChart",
height: 450,
duration: 250,
width: 600,
mode: "size",
groupColorByParent: true,
labelThreshold: 0.04,
showLabels: true,
key: function (d,i){return d.name;},
labelFormat: function (d){if(mode === 'count'){return d.name + '#' + d.value}else{return d+ ' '}},
}
doesn't do the job for me, but here http://krispo.github.io/angular-nvd3/#/sunburstChart it somehow works if you check the "showLables" checkbox
Same problem here, solved by updating your nvd3 lib to 1.8.5.
im using google api for line graph in my web application. in that line chart i dont want x axis line and y axis line, but i cant to fine how to remove the lines except the graph. could you please help me. i used this example for my practice
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales', 'Expenses'],
['2004', 1000, 400],
['2005', 1170, 460],
['2006', 660, 1120],
['2007', 1030, 540]
]);
var options = {
title: 'Company Performance'
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
you cant remove or disable your x and y axis in google api the alter way is to set the baselineColor and gridlineColor same as the background color and set the textPosition to none.
vAxis:{
baselineColor: '#fff',
gridlineColor: '#fff',
textPosition: 'none'
}
With the current version of Google Charts, the following removes axis lines:
hAxis: {
baselineColor: 'none',
ticks: []
},
vAxis: {
baselineColor: 'none',
ticks: []
}
I'm new to jqplot, when I want to draw a bar chart, x axis is date, interval is 1 day. This is part of my code:
axesDefaults:{
tickRenderer: $.jqplot.CanvasAxisTickRenderer,
tickOptions:{
fontSize:'10pt',
},
},
axes:{
xaxis:{
renderer:$x_renderer,
tickOptions:{
formatString:'%Y-%#m-%#d',
},
rendererOptions:{
tickOptions:{
angle:-90,
}
},
label:'$label',
tickInterval:'86400000',
},
yaxis:{
tickOptions:{
formatString:'%.2f',
},
autoscale:true
},
},
highlighter:{
show:true,
},
But I find the width of each bar is too large to cover each other. How to fix it?
Thanks!
The AnthonyLeGovic answer is indeed correct, but if you need to change the column width according to the number of data points you can do the following:
// Get the size of the container of the plot
var width = jQuery(containerName).width();
// Divide by the number of data points.
width = width / number_of_data_points;
// Reduce the width to a % of the total for each data point.
width = (width * 20) / 100;
// Set the value
$.jqplot(containerName, [data],
{
// whatever
// ...
seriesDefault:
{
renderer: $.jqplot.BarRenderer,
rendererOptions: { barWidth: width }
}
// whatever
// ...
}
Note that I'm not taking into account the width of the legend. The legend width can only be obtained after plotting, so if you want to reduce the column width considering even the width of the legend you must do it after plotting, and then replot.
I've prepared a fiddle that shows an example.
Hope it helps.
You can specify it in your series options :
seriesDefault:{
renderer: $.jqplot.BarRenderer,
rendererOptions: {
barWidth: 5
}
}
Don't forget to include barRenderer plugins.
For more documentations about bar chart on jqplot please take a look at : Jqplot documentation
I added below code and I got the result.
The reason behind my width was coming too large because of bar-width were not set in series Default block.
seriesDefault:{
renderer: $.jqplot.BarRenderer,
rendererOptions: {
barWidth: 5
}
}

I'm running jqPlot and for some reason the color-coded squares that should show up inside the pie renderer's legend are not appearing. I'm wondering if it has anything to do with the fact that I'm using twitter bootstrap? I'm not using any other css libraries.
var plot1 = jQuery.jqplot('chartdiv', [graphData],
{
grid: {
shadow: false,
background: '#FFFFFF',
},
seriesDefaults: {
// Make this a pie chart.
renderer: jQuery.jqplot.PieRenderer,
rendererOptions: {
// Put data labels on the pie slices.
// By default, labels show the percentage of the slice.
showDataLabels: true,
padding: 20,
startAngle: 270
}
},
legend: {
show: true,
location: 'e',
fontSize: 11,
marginTop: 10,
}
});
Are you sure you are loading the CSS of the jqPlot correctly (i.e. the url/href is pointing into the right location)?
This is your code with jquery.jqplot.css loaded.
This is your code without the css.
This one is with both the jquery.jqplot.css and the bootstrap (downloaded without jQuery plugins and not linking the img folder that comes with the download). Here all appear correctly, thus you must double check the href of the jquery.jqplot.css.
