I am using jqplot 1.0.8 and experience problems with the CategoryAxisRenderer. The y-axis displays numeric values and the x-axis displays either numeric values or string values. That is why I chose the CategoryAxisRenderer. Basically, everything is rendered correctly except for the highlighter. If I hover over a point, I do not get the value for the x-axis, but instead, I get only the index of the value.
Initialization
PLOT = $.jqplot(that.getId() + '-CONTENT', [array], {
width: $('#' + elemId).width() - 30,
height: 500,
axesDefaults: {
tickRenderer: $.jqplot.CanvasAxisTickRenderer ,
},
axes: {
xaxis: {
renderer: $.jqplot.CategoryAxisRenderer,
tickOptions: {
angle: -90,
fontSize: '8pt'
}
},
yaxis:{
min:1
}
},
highlighter: {
show: true,
tooltipLocation: 'ne',
sizeAdjust: 7.5,
useAxesFormatters: false,
formatString: '%s, %d'
},
cursor: {
show: false
}
});
Output
Expected results
1) 1978, 1
2) University of Ljubljana, 37
I got the exactly same problem and my own solution is that customize the tooltip using tooltipContentEditor.
highlighter: {
tooltipContentEditor: function (str, seriesIndex, pointIndex, plot) {
var content = plot.axes.xaxis.ticks[pointIndex] + ", " + str.split(',')[1];
return content;
}
},
If you want to display the categorized x-axis values, you have to follow this workaround: https://groups.google.com/d/msg/jqplot-users/ZeXgxATxMyI/Fs3DnBAecu0J

I am using jqplot to create a graphic.
I have an issue about the nonexisting values.
I create a graphic with 5 lines as shown http://www.popularjava.net/wp-content/uploads/statisticGraphic.png
As you see from the picture, there is only one value for some lines such as orange line.
However, I would like to show such nonexisting values with y=0.
I mean, I want to put y=0 for all dates if there is no point for any date.
Here is my code.
var minGraphicXValue = response.minGraphicXValue;
var maxGraphicXValue = response.maxGraphicXValue;
var dataSeriesList = response.dataSeriesList;
var plot1 = $.jqplot('countGraphicGrid', response.countArray, {
title: 'Count/Time Graphic - ' + selectedItemType + ":" + itemValue + " - " + StatisticGraphic.selectedGraphicPeriod,
axes: {
xaxis: {
label: "Time",
labelRenderer: $.jqplot.CanvasAxisLabelRenderer,
labelOptions: {
fontFamily: 'Helvetica',
fontSize: '14pt'
},
renderer: $.jqplot.DateAxisRenderer,
tickRenderer: $.jqplot.CanvasAxisTickRenderer,
tickOptions: {
formatString: StatisticGraphic.tickFormatPattern,
angle: -30
},
tickInterval: StatisticGraphic.tickIntervalTime,
min: minGraphicXValue,
max: maxGraphicXValue,
drawMajorGridlines: false
},
yaxis: {
label: "Count",
tickOptions: {
formatString: '%d'
},
min: 0,
max: 100,
autoscale: true
}
},
legend: {
show: true,
placement: 'outside'
},
seriesDefaults: {
rendererOptions: {
smooth: true,
animation: {
show: true
}
},
showMarker: true
},
series: dataSeriesList,
highlighter: {
show: true,
sizeAdjust: 7.5,
tooltipOffset: 9
},
grid: {
background: 'rgba(57,57,57,0.0)',
drawBorder: false,
shadow: false,
gridLineColor: '#666666',
gridLineWidth: 1
}
});
I think the best way to do it is to format your data before your render them on your plot.
I mean add values for your nonexisting ones. You can use your (min|max)GraphicXValue and set them to 0 if non existing.
I am using jqplot charting library to draw the bar chart in my application.
I have used following code to draw the horizontal bar chart.
var plot = $.jqplot('chart', [dataSlices], {
seriesDefaults: {
shadow: false,
renderer: $.jqplot.BarRenderer,
pointLabels: { show: true, location: 'e', edgeTolerance: -55 },
rendererOptions: {
barDirection: 'horizontal',
barMargin: 5,
highlightMouseOver: false,
fillToZero: true
}
},
axesDefaults: {
},
axes: {
grid: {
drawBorder: false
},
xaxis: {
pad: 0,
tickOptions: {
show: true,
mark: 'cross',
thousandsSeparator: ',',
formatString: "%d"
},
numberTicks: null,
min: null,
max: null,
showTickMarks: true
},
yaxis: {
renderer: $.jqplot.CategoryAxisRenderer,
ticks: yAxisLabels,
tickOptions: {
showMark: false,
showGridline: false
}
}
},
grid: {
gridLineColor: '#ffffff', /**/
borderColor: '#509790',
background: 'rgba(0,0,0,0)',
shadowWidth: 0,
borderWidth: 0,
shadow: false
},
series: [{ color: '#f39f02' }]
});
$.jqplot.thousandsSeparator = ',';
//$.jqplot.formatString = "%'d";
gridCanvas = $($('.jqplot-grid-canvas')[0])
seriesCanvas = $($('.jqplot-series-canvas')[0])
gridCanvas.detach();
seriesCanvas.after(gridCanvas);
plot.replot({ resetAxes: true });
I am getting the chart without grid lines.
Is there any idea, how to do this?
Call the following lines after replot, you will get the expected result
gridCanvas = $($(item + ' .jqplot-grid-canvas')[0])
seriesCanvas = $($(item + ' .jqplot-series-canvas')[0])
gridCanvas.detach();
seriesCanvas.after(gridCanvas);
I tried its working fine for me,.
GridLineColor set to white (#FFFFFF) explains why you aren't wiewing vertical lines.
BorderWidth set to 0 explains why you aren't viewing borders of your plot (drawn with a size of 0px)
If you doesn't need particular color and/or size of your grid (vertical lines and border) remove the grid part of your code.
If you need particular color and/or size choose carefully your values (#FFFFFF if your background if already white - or a borderWidth of 0px) :
grid: {
gridLineColor: '#FF0000',
borderColor: '#509790',
background: 'rgba(0,0,0,0)',
shadowWidth: 0,
borderWidth: 2,
shadow: false
},
Please see working example here (I have delete yAxisLabels and add fictional data in order to draw a plot)
I want a pie chat using jqplot which will show the exact number (not percentage) inside each slice of pie chat.
$(document).ready(function(){
var s1 = [['Sony',200], ['Samsumg',40]];
var plot8 = $.jqplot('chart1', [s1], {
seriesColors: [ "#533E6A","#B4150C"],
grid: {
drawBorder: false,
drawGridlines: false,
background: '#ffffff',
shadow:false
},
axesDefaults: {
},
seriesDefaults:{
renderer:$.jqplot.PieRenderer,
rendererOptions: {
showDataLabels: true,
// sliceMargin: 2,
startAngle: -90
// diameter:30
}
},
legend: {
// show: false,
rendererOptions: {
numberRows: 1
},
location: 's'
}
});
});
Below is the jsfiddle(http://jsfiddle.net/JWhmQ/2032/) but it is showing the slice in percentage..instead i want the actual number(like 200 and 40).
You need to add
dataLabels='value'
, in the rendererOptions, as described here. I fixed your jsfiddle here.
The labels I use on axis for my graph contains text with more than one word. Like this:
and it looks bad. I tried (as you can see on the graph) to replace the wit spaces with brs or with \n in order to render the text in multiple lines. The result is not what I was expected to get.
How to split the ticks text into words and to draw each word on a row?
The <br/> is working will trying to split your text into two lines. See a working example here.
In order to make it work, don't forget to load some jqplot plugins : CanvasAxisTickRenderer, CategoryAxisRenderer.
You then need to apply tickRenderer: $.jqplot.CanvasAxisTickRenderer to your serie(s). You need as weel to apply renderer: $.jqplot.CategoryAxisRenderer onto your yaxis.
For me, <br/> didn't work and \n did.
My configuration:
jQuery.jqplot(element, configuration.series, {
stackSeries: true,
animate: false,
captureRightClick: false,
seriesColors: ['green', 'blue', 'yellow', 'orange', 'red'],
seriesDefaults: {
renderer: jQuery.jqplot.BarRenderer,
rendererOptions: {
shadowOffset: 0,
barDirection: 'horizontal',
highlightMouseDown: false,
barWidth: 20,
},
pointLabels: {
show: false
}
},
axesDefaults: {
min: 0,
minorTicks: 0,
tickOptions: {
formatString: '%d'
}
},
highlighter: {
show: false
},
axes: {
yaxis: {
renderer: jQuery.jqplot.CategoryAxisRenderer,
ticks: configuration.labels
},
xaxis: {
ticks: configuration.ticks,
label:'Hours',
labelOptions:{
fontFamily:'Helvetica',
fontSize: '10pt'
},
}
}
});
I have a jqPlot hor. barchart like this one. jq plot - getting linear x axis ticks
I want to be able to put y-axis tick labels (like software and services, israel in the pic)
on top of respective bars using some parameters or renderer instead of fiddling with css.
Is there an easy way to do that? Thanks in advance.
so far, my code looks like below.
`
function drawChart() {
var data = new Array(3);
for (var i = 0; i < data.length; i++) {
data[i] = new Array(2);
data[i][0] = Math.random() * 100;
data[i][1] = 'text-' + (i + 1);
}
var plot2 = $.jqplot('votingresult', [
data,
], {
seriesDefaults: {
renderer: $.jqplot.BarRenderer,
pointLabels: { show: true, location: 'e', edgeTolerance: -15 },
shadow: false,
rendererOptions: {
barDirection: 'horizontal',
barPadding: 20,
barMargin: 0,
barWidth: 20,
varyBarColor: true,
}
},
gridPadding: { top: 0, right: 0, bottom: 0 },
grid: {
drawGridLines: false,
drawBorder: false,
shadow: false
},
axesDefaults: {
showTicks: false,
shadow: false
},
axes: {
yaxis: {
renderer: $.jqplot.CategoryAxisRenderer,
tickRenderer: $.jqplot.CanvasAxisTickRenderer,
tickOptions: {
fontSize: '10pt',
mark: 'inside',
showLabel: false
}
}
}
});
}`

Jeroen: I have looked into point labels. But, here, I am talking about axis label to be inside the graph.
I had the same challenge and ended up just writing a function to append content to the graph DIV rather than try and fiddle with JQPlot. You just have to adjust the barMargin option to account for the spacing.
function makeSectionLabels(jsonObject, domObject, topPadding, spacing) {
var html = "<div class='bar-chart-sections' style='padding-top:"+topPadding+"'>";
$.each(jsonObject, function(index, value){
html += "<h5 style='margin-bottom:"+spacing+"'>"+value+"</h5>"
});
html += "</div>"
$(domObject).append(html);
};
