I am very curious of how tooltip in Cubism.js works. http://square.github.io/cubism/
Since i am quite new to javascript, I will appreciate if someone gives me any hint. I am really interested in making tooltip in which data value shows by hovering cursor around the graph.
I have seen the library but could not find anything regarding the tooltip..
Thank you so much
The tooltips showing on the graph itself there are just spans above the canvas showing the graph.
The axis labels at the top is built using svg.

I need your help!
I have to show a tooltip on the curve using d3, I already have that functionality and it does work, but now I have to show two separated tooltips on one curve.
Let me explain, I used to use this curve appearance, it is a simple d3 curve, and the tooltip works perfectly. And now need to use this curve appearance -
https://github.com/d3/d3-shape#curveLinearClosed
And I'd like to know how to show one tooltip on the bottom of the curve and a second on the top.
So far my implementation of the tooltip works only on the top, I think that happens because d3 draws the bottom line on its own.
So did anybody have a similar problem?
This is a picture how it should look like:
I do not need the code, I'd like to hear any thoughts or ideas about that.
I'm looking to make a responsive donought chart with CanvasJS but my client wants a "broken" donought. Like with a piece missing.
Can it be done? If so, how?
Or else, if it cannot be done, could another responsive graph library be recommended that can do this?
Thanks
EDIT:
I managed to "fake" a gap in it my setting one datapoint to transparent. However, it's not "real" as the transparent part is still a part.

I don't know about canvasJS, but you can draw a polygon with inner rings in canvas, see the answer here: Polygon with a hole in the middle with HTML5's canvas
You can also do it with SVG which some web mapping libs used for this purpose before the advent of the canvas element.
Can someone please let me know how should I implement this kind of chart? I need to use a javascript library for implementing a chart which has a big circle (100%) inside which there are small semi-circles which divide the bigger circle. Its kind of pie chart but not exaclty pie chart. I want semicircles inside a big circle It looks like a bubble chart to me but it is enclosed within a circle. I am not quite sure which library should I use for this?
Any help would be appreciated!
write your own.
you can make divs into circles with css(border-radius), even into triangles(3d transform within div dat gives no overflow) if you try hard.
then you could utilise absolute positioning to place them where you want them.
That way you dont even need javascript or a library.

Just a small example what you can do with google and some inventive thinking ;-)
I'd like to add a vertical line which will display a tooltip when hovering on it. I'd like to flag a company event this way however I can't really find a way to that with JqPlot.
Thanks in advance,
Lashus.
I think for this one you might use the approach I used to provide a line highlight option in jqPlot, details of which are in this answer. There you have the algorithm for detection when the mouse is over a line.
When you detect that the mouse just entered a line and the tooltip is not visible then build it and show it. Also do not forget to hide the tooltip when mouse moves out of the line. When implementing this part you will certainly find useful the code from this answer.
It shows how to add a custom tooltip on a stacked bar chart, but the code could be easily adopted to your needs.
PS: I assumed that the vertical line will be at some point drawn on some canvas by you (your code). If it is something else that you had on your mind saying vertical line then please explain. Otherwise good luck. :)
I've been using the chart API to draw a cross sectional profile of a landmass, using a slightly modified version of the chart example shown here.
however, I now need to draw a line of sight between the two end points, as well as a Fresnel(1) zone between the two. can this be done through the interactive chart API? or is there a better way to get this done?
also, I would like to 'select' the first and last entries to display their elevation, however my code doesn't appear to do anything:
Chart.setSelection([{row:0,column:null},{row:Results.length - 1, column:null}]);
After finding some other problems with the visualization API, I just gave up and did the whole thing using Raphael instead, works way better :D
EDIT: didn't know you couldn't answer your own posts within two days :| kinda of annoying since I've spent like a week straight trying to fandangle the bleeding chart -.-
