I'd like to plot a bar graph but in such a way that the bar graph isn't contained within a square/rectangle, but rather have the bottoms of the bars follow a spline. How can I get seaborn to output something like this? seaborn.bargraph doesn't have any parameters that would take a spline, which makes it really hard to combine data visualization and art.

I have a set of polygons where the position of their vertices (corners) are defined as latitude/longitude values.
I want to use D3 to draw these. I don't want anything fancy (like a background containing the world map, etc). The only thing I want to do is to draw the polygons.
I have looked up on Google for a solution, but what I find is things like http://datamaps.github.io or https://github.com/mbostock/d3/wiki/Geo-Paths and they all show a background of the world map or the like which is what I don't want to do.
Suggestions are welcome.
In your particular case, using the geo functionality of D3 seems like overkill -- all you need to do is use the D3 scales to convert the coordinates to screen coordinates, i.e.
var scale = d3.scale.linear().domain([minCoord, maxCoord]).range([minScreen, maxScreen]);

I am using Dimple.js to plot several data series and I need to add a candlestick or hi/lo series on to my existing chart. After some analysis, I have found two possible approaches to do this:
1) Use the floating bar option in Dimple.js. Since the "widths" (heights on the chart, but widths for the floating bar) would be all different, I would need a different data series for each candlestick. This feels like a hack, but the one advantage is that this would be using Dimple to do all the rendering. I would probably not go this route unless some had a thought on how to make this less of a hack.
2) Drop down to D3 to draw lines between the points. I can use Dimple.js to graph both the top and bottom elements of the candlestick, then use D3 to draw the line between the points. I would do a selectAll() on one of the series, and then draw a path to the related point in the other series.
If there are other suggestions on an approach, please let me know. Thanks!
You can use this example to build candlestick charts using d3.js
I'm new to JavaFX and implemented a scatter chart with various data series. That works well so far, but I want to highlight the data in a specific area as these are ok and all outside the area are bad. so my plan is to draw two lines in the chart, for example one at y=80 and one at y=120. is there a comfortable way to accomplish this? I wanted to avoid drawing the lines with a LineBuilder or so.
If I have a plot like
RevolutionPlot3D[Piecewise[{{x^2,0<x<1},{x^(-1),1<x<3}}],{x,0,3}]
is there anyone to add labels within the plot?
For example, if I wanted to label specifically the position x=1 as something like "Enters magnetic field," is there any way I could do it?
So I am using jqPlot to display distance (y-axis) over time (x-axis) in a simple line graph.
However, while I have actual distances as the underlying data used to position the points, I'm not interested in displaying those distances on the y-axis.
Instead, there are a series of landmarks at given distances, that I want to appear on the y-axis as a 'tick' next to the appropriate point for the distance to that landmark. That way the line appears to "pass" each landmark as it travels upward.
Currently I'm "faking" this by hiding the ticks and putting a manually-created series of labels next to the graph. This works well enough, but I had to disable vertical zooming because if the user chose to zoom in, the labels would not match up with the actual distances. My users would really like to zoom in vertically, however, and I want to allow them to.
Therefore, does anyone know of a way (a plugin or similar) that would allow me to associate custom labels with given tick marks in jqPlot, that will match up nicely and respond to zooming? It would be necessary to hide some of the landmarks if the graph is zoomed out too much, so that would have to be a feature.
Alternatively, if someone knows of a "zoom event" that passes in the min and max y values, I could probably recreate my manual labels with that data, so let me know if you know of a way to get that information. I haven't been able to find one.
I would need to see a bit of your code to customize it to the distance but to start with you could label the ticks and it will display over the size of the chart.
axes:{yaxis:{ticks:['DiscanceA','DiscanceB', 'DiscanceC', 'DiscanceD', 'DiscanceE'],
renderer: $.jqplot.CategoryAxisRenderer,},
Let me know how it goes and if you have any code lets see it!
