How would you go about reproducing this d3 code in Bokeh?

I am attempting to plot several great circles between points on a world map. I am using sf to generate the great circles, largely following the method outlined here. I am able to generate the plot and lines all ok, except several of the lines wrap around behind the globe so to speak, and I end up with a horizontal line connecting the two points where the great circle paths wrap around - see "Correcting gcIntermediate" here for a visual explanation and a solution for gcIntermediate. Looking at the sf dataframe that has been created, my guess is that I need to split the items where absolute longitude difference is greater than 180 degress into two sf lines. I can kind of see a method that involves many lines of code brute forcing the sf dataframe to resolve this issue, but would very like to see if there are any other better ideas to solve this elegantly.
st_wrap_dateline to the rescue!
path.sf <- st_wrap_dateline(path.sf,
options=c("WRAPDATELINE=YES", "DATELINEOFFSET=180"))
Then plotting this with ggplot2 seems to plot all ok.
I'm trying to do something like this:
In d3.js. I can draw the donut chart fine but I'm struggling on how I can have multiple colors within an arc. Is there a way I plot multiple arcs within the same arc and style them independently?
Rather than putting multiple colors within a single arc, I would recommend having a single arc for each color. This way, if your data changes, you can just change the lengths of each arc, rather than changing the gradient you're using.
A good example of this is here: d3 gallery donut chart
I'm using fusion chart free and facing one issue that chart lines overlap each other when there are same values for those lines. Please see below the image where you can see four graph lines (Reputation, Quality of Instruction, Value of Job, Would seek repeat work) overlaps as there are same values for all four lines.
Is there any ways to convey internet Users graphically that there are same values for all four lines and that's why showing only one line?
If the values of the data plot in the MSLine chart are same then then lines will overlap and the resultant viewable plot will be a single line.
However, you can notice the number of data sets by viewing the Legend element in the chart.
I am hoping someone can help me with an issue setting points on a bar graph with multiple start and stop points along each series. Note the first and last bars each have multiple starting and ending points.
Any tutorials or sample code would be greatly appreciated. sorry the image is so small.
What you are looking for are range bar charts
chart.Series[0].ChartType = SeriesChartType.RangeBar;
as always with MSchart, I'd recommend you take a look at the samples provided HERE. It has a section that demonstrate how to use RangeBar charts to achieve what you described.
I want a chart that has several separate series running in rows across. They are largely separate charts and should not overlap, but all share the same horizontal datetimeaxis. They don't share the same y-axis, however and that's where I'm getting stuck.
I have tried having a linechart series and then a plotchart series, but it will only allow a single <mx:series> per chart without having them inside the same series which as far as I can tell will place the charts on top of each other in the z-axis. I can stack them and have them completely separate charts, but it was proving to be somewhat irritating having them align correctly.
Is there any reasonable way of combining multiple charts into one like this? Basically having rows in a table where each row is a different chart but the columns are consistent. or am I going to be best served just by stacking separate ones?
an illustration of what i'm going for is here: http://i.stack.imgur.com/8Renf.png
As far as I'm aware, the only way to do this is to stack separate charts. With a little care, it is possible to set things up so that the x-axes line up properly -- the project my team is working on has this.
