I have lots of svg element containing each one a line chart. I'd like to display these charts at groups of four. If I understand well from the documentation, it'd be better to use a grid for this purpose since I can select position I want (single box of the grid) for a specific graph. Is it true, or is there another better way to do this?
NB: charts are built each one from different datasets and using d3.js and so javascript.
Thank you so much for the help.
If it's possible, I'd like you to show me a code snippet just to understand better.
Thank you again.

I want to create a better visualization than the one you can see in the image:
Currently, this is a HTML page with spans as rectangles. Of course I got follow this way to get a more dynamic presentation of the data. But I'm curious, if this can be done with D3.js in a better way.
Is there a chart/visualization type that can be used to achieve this?
I have 3 similar pie charts. They use same dimension but different groups so, their legends look the same. Instead of having 3 same looking legends, I'd like to bind only a single legend to those charts. I tried creating a legend separately and assign it to the charts, however, it didn't work. Is there actually a way to do such thing?
This is not directly supported by dc.js, but it is very similar to a legend on a composite chart. I think if you were willing to do some hacking, you could override the legendables function on the chart you want to put the legend with, and have it accumulate the legendables from its sibling charts.
Take a look at pieChart.legendables:
https://github.com/dc-js/dc.js/blob/master/src/pie-chart.js#L419
And then compositeChart.legendables
https://github.com/dc-js/dc.js/blob/master/src/composite-chart.js#L363
for inspiration.
If this is too much hacking for you, please file an issue. It would certainly be nice to support!
I am looking into trying to stack completely different series/charts on top of each other but on the same chart. For instance I could have two charts stacked vertically and when I move the cross-hair on one, it will move on the other almost as if the charts are linked. As well, I'd when I zoom in one, it would trigger the other to zoom. Please see the image at the bottom I "doctored" to give you an idea of what I'm trying to accomplish.
Things I've tried:
creating two completely separate charts and stacking them.
This is the closest I've gotten to what I need but they are still separate entities so it won't work for what I need, cross-hairs/zooming/etc. all need to work as though the charts are linked/combined.
In the options I tried the "stacking" option.
this won't work because it "stacks" or groups data, I want to literally have two separate series that might not have anything in common with each other.
Rendering muliple y-axis.
the only issue with this is that it's overlapped data, I'd like it to be offset so we can see it in a stacked layout.
I'm pretty new to using this library so if any of my terminology or explanation doesn't sound right, please sound off and I'll elaborate.
Thanks everyone!
I'm replacing DotNet Charting charts with KendoUI. I need to be able to put a multiple line label on a line chart. See the image below with the red circle on the label. Any suggestions would be greatly appreciated.
See my current chart and the DotNet Cart I need to replace:
Short answer: you can't.
Long answer: You can't, but you there is a bug in Kendo that will let you... sort of.
Kendo is creating an SVG on the fly for your chart. SVGs are just XML, and you can inject XML into the element via the javascript config.
For your label, you have to use elements to position text. See the SVG spec for this element: http://www.w3.org/TR/SVG/text.html#TSpanElement
The problem here is that Kendo uses left-justified text, and you can't change the parent element with this bug. That means you have to offset everything by hand, one pixel at a time. If your text is static, this might work; if it is dynamic, I wouldn't even attempt it.
You might be able to hack something together via JS, and manipulate the SVG on the fly each time Kendo modifies it... but you may as well write a charting library if you're going to that much work.
EDIT: For your use, it might be better to rotate the labels, if you don't have to mirror the old display exactly.
I am trying to create a pie chart and am customizing the example here: http://raphaeljs.com/pie.html
I need to draw lines from the labels to the slices but IE is giving me trouble and I'm not sure what to do about overlapping lines and labels.
Has anyone done this before?
this maybe useful to you:
Overlapping issues can usually be solved by using:
a) ".toFront()" on the raphael element, that should appear in foreground
b) ".getBBox()" at your label and use its parameters to figure out the starting point.
those functions can be looked up in the raphaeljs reference.
.getBBox() should be a good way to start, when you try to connect elements. you can easily figure out its meassurements and use those values (x,y,width,height) to calculate the entry point of your path
that makes it easier to avoid any overlapping at all. but keep in mind the end SVG elements are directly placed within the dom and therefor are meant to work in layers.
overlapping / partially hiding elements often offer you a great animation potential and are not really a bad thing to work with.
