I'm working on putting together a pretty basic stacked bar chart using Primefaces. The chart itself seems to build just fine. However, the legend is being placed over the chart data. I know you can move the legend to any compass ordinal (n, s, w, e, se, sw, ne, nw), but I'd actually like to move it OFF the data.
The code to get it in:
<p:barChart id="stackedKWH" value="#{kwhSalesBeanManager.kwhSalesChart}" legendPosition="e" style="height:300px;width:800px" title="kWh Sales by Type" stacked="true" barMargin="10" min="0" max="125000000" />
And what it currently looks like. Would like to move that legend off the chart to the right.
Try to add this :
function extLegend()
{
this.cfg.legend= {
show: true,
location: 's',
placement: 'outsideGrid'
};
}
and add this inside your barChart component :
extender="extLegend"
Now the best solution would be defining the placemant on chart model:
...
modelChart.setLegendPlacement(LegendPlacement.OUTSIDE);
...
Looks like you should use javascript for this purpose.
something like that:
var legend = $('table.jqplot-table-legend')[0];
legend.setAttribute('style', 'position: absolute; z-index: 3; right: -100px; top: 25px;');
I tested it on this page: http://www.primefaces.org/showcase/ui/barChart.jsf

I am trying to remove the label in the linechart. For that i have tried by giving empty label but in the graph it dispayed color box without the label .
ChartSeries boys = new ChartSeries();
boys.setLabel("");
If i tried without setting the label. It displayed color box with "null" as label.
I don't know if this is an option for you, but you could hide the entire legend box using css. Something like this:
.jqplot-table-legend {
display: none;
}
Solved my issue
yourChart.options = {
legend: {
display: false,
}
};
I've got two series in an Highchart graph. Both are handling event like mousemove (to show tooltip) and mouse click.
Unfortunatly one of those series is an area serie which block any event to be triggered by the other one.
Let's say I've got those series with those plot options :
plotOptions: {
series: {
cursor: 'pointer',
point: {
events: {
click: function() {
alert ('Category: '+ this.category +', value: '+ this.y);
}
}
}
}
},
series: [{
color:'red',
data: [29.9, 51.5, 16.4, 19.2, 44.0, 16.0, 35.6, 48.5, 26.4, 4.1, 9.6, 54.4]
},
{
type:'area',
data: [39.9, 75.5, 120.4, 150.2, 130.0, 120.0, 140.6, 158.5, 216.4, 194.1, 95.6, 54.4]}
]
}
as seen in this JSFiddle
I can never click or see the tooltip on the red series points.
What I could do is to change the order of the series so the red one is over the blue one.
( like this). But I've got situations where I've got several area graphs over each other like that. In this case, change the order won't help.
Is there a way I can handle events through the fill area?
Ok I found a way that suit my need : manimulating SVG element order as indicated in this topic :
SVG re-ordering z-index (Raphael optional)
I'm using this code in the redraw event of the chart :
redraw : function(){
//get a reference on the first series svg element.
var svgSeriesParent = document.querySelectorAll('.highcharts-series')[0];
//loop on all the path drawn by highchart
var pathArray = document.querySelectorAll('path');
for (var pathIndex = 0; pathIndex < pathArray.length; pathIndex++) {
var pathObj = pathArray[pathIndex];
//if attribute fill is not "none", this is an area path.
if ($(pathObj).attr('fill') !== "none") {
//move the current fill path before the first series svg element.
svgSeriesParent.insertBefore(pathObj, svgSeriesParent.firstChild);
}
}
}
See the result in this JSFiddle
Limitation :
The fill area doesn't have the same svg group anymore thus, hidding / showing the series is broken : all the fill area are considered being part of the first series. (click in the legend to see it).
In my case I don't need to hide series so I'll go on with this solution.
The svg order manipulation is not complicated that's why I would expect highchart to manage this case : add a fillZIndex parametter doesn't seem difficult and could be pretty usefull...
Only what comes to my mind is using 4 series, 2 area and 2 lines and use index.

I'm trying to write a topbar for my application that should contain mainly the app logo (a small image) and the app title (just text). Moreover, I'd like this topbar to automatically resize according to the window's height.
I'm new to QML, but I suppose that I should wrap these components inside a Row or a RowLayout component. This is my sample code:
import QtQuick 2.0
import QtQuick.Layouts 1.0
Rectangle
{
id: mainwindow
width: 1024
height: 600
Row
{
id: rowlayout
height: logoimage.height
spacing: 5
property int count: 3
anchors
{
left: parent.left
right: parent.right
top: parent.top
}
Image
{
id: logoimage
source: "qrc:/images/resources/images/icon.png"
height: mainwindow.height / 20
anchors.top: parent.top
anchors.left: parent.left
}
Text
{
id: logotext
text: qsTr("This is my logo text")
font.pixelSize: parent.height
font.family: "Sans Serif"
height: parent.height
verticalAlignment: Text.AlignVCenter
anchors.top: parent.top
anchors.left: logoimage.right
}
/*
Rectangle
{
id: otherrect
height: parent.height
color: "lightgreen"
anchors.top: parent.top
anchors.left: logotext.right
anchors.right: parent.right
}
*/
}
}
I tell to the Row component that its height should follow the logo's height, and to the Image (logo) component that its height should be 1/20th of the Rectangle (mainwindow) component.
Using a Row container, the code behaves as expected but I get an annoying warning (QML Row: Cannot specify left, right, horizontalCenter, fill or centerIn anchors for items inside Row. Row will not function.) and I have to do a lot of anchoring. Conversely, if I use a RowLayout container, I can remove most of the anchors but the Image completely ignores its height attribute (but the text still resizes correctly). So the questions are:
is this a bug of the RowLayout component? I'm using Qt-5.1.0-Beta with Android support, so this could be an explanation
how can I use a Row component without using anchors in its children and thus avoid the warning?
I'm missing something important or I'm almost on the right track but I have to bear with this beta of Qt until a stable version is released?
You said that you get the expected behavior with Row, so you should probably use it. The warning that Row is giving is asking you to remove the vertical anchors (top and bottom) from its child elements.
The Row element provides horizontal (left and right) anchor-like behavior for its child elements, but it doesn't mind if you use top and bottom anchors (notice that top and bottom were not in the warning).
In other words remove "anchors.left" and/or "anchors.right" lines from "logoimage", "logotext", and "otherrect" (if you plan on uncommenting it at some point), but not the "anchors.top" lines, and that should stop the warning and keep the correct behavior.
An alternative is to just remove the Row element and use Item or FocusScope (if you plan on having input elements in your "top bar" area), which will not try to take over anchoring operations, and that may be a better fit for you if you really like anchors.
You need to give a width to your layout if you want it to strecht its children, either with width: parent.width, or better, with anchors { left: parent.left; right: parent.right } and no anchors on vertical lines inside childrens of the layout.
1) NO, it is no a bug of RowLayout
2) Consider that RowLayout is preferred to Row because is most expressive for components placing. The Row component is better that Rowlayout only for graphics or animation apps
3) The stable version is now available, but your errors are not bugs ;)
When using the JavaFX 2.0 scatter chart the plotted dots are graphed with the top left corner of the dot touching the point rather than the center of the dot on the point. So rather than it looking like it is plotting at the point (1, 1) it looks more like it's at (1.1, 0.9). Does anyone know how to fix this?
There is a bug in a way ScatterChart draws shifting plotted dots.
Until fix as a workaround you can override dots style class. To perform that add new file "style.css" to the same package with your main class and next content:
.chart-symbol { /* solid circle */
-fx-background-color: #f9d900;
-fx-background-radius: 5px;
-fx-translate-x: -4px;
-fx-translate-y: -4px;
}
In the code where your main scene is created add next line:
scene.getStylesheets().add("style.css");
I have just changed my version of Flot from 0.6 to 0.7, however, when I do this, the legend in my Flot graph changes style. Previously, I had used the "LabelClass" attribute to change the style but on reading the source for 0.7 I see that "labelClass" is no longer an option and I appear to be forced to use the "table" CSS definition that is used throughout the site that I'm working on. Because of this I can't change the site's CSS "table" definition.
Is there another good method for changing the definition of a legend or am I stuck?
Apologies in advance is this is just a newbie question
Kind Regards
It has changed names is all, the new class is legendLabel for the labels and legendColorBox for the color box.
You can see this in jquery.flot.js.
EDIT in response, it seems that the question is how do you style the whole table. Assume your flot placeholder is something like this:
<div id="foo" style="width:600px;height:300px"></div>
Then you can define CSS like this:
#foo > div.legend > table {
border: 2px red solid;
}
See it here in action: http://jsfiddle.net/ryleyb/YkDpG/1/
Another way to style the legend is to use the jQuery .css() (http://api.jquery.com/css/) method after the chart has been plotted.
For example:
$.plot($("#chartFoo"), pieChartData, options);
$("#chartFoo div.legend table").css("border", "1px solid #888888");
$("#chartFoo div.legend table").css("background", "#ffffee");
or:
$.plot($("#chartFoo"), pieChartData, options);
$("#chartFoo div.legend table").css({ border: "1px solid #888888", background: "#ffffee" });
