QUESTION
I have a VueJS component which is a svg map image of the united states. I previously used jquery to create hover effects to display the information bubble. I am trying to convert this to a pure Javascript solution. It seems a click event is the easiest to implement given vuejs mousemove seems to be less reliable. I have added the click event in method and I am trying to capture the SVG path location and steal the top and left position to enable the info box there. I have tried this.offsettop and this.offsetleft but they return undefined.
Jquery code I am trying to convert:
...ANSWER
Answered 2021-Apr-30 at 17:11The solution was found in the comments on the question.
In summary, the issue was understanding how to position the #info-box
element. Using the getBoundingClientRect()
function, we can get the position of any element relative to the entire document. To get the position of the clicked path element, simply subtract the top and left of the #us-map
from the top and left of the path. This will give the position for the top left corner of the path, relative to the containing element. We can then use that to position the #info-box
.

QUESTION
My question is very similar to D3 V4 Properly placing a bubble in the US Map, but the map I'm using is a map of Scotland's local authority districts instead so I can't quite see how to apply either of the solutions.
I'm creating a bubble map on top of a choropleth map of Scotland, with circles at specified locations which I'm providing as latitude/longitude coordinates.
However, the locations of the circles are completely out - the circle for Aberdeen is in the sea!
Based on D3 V4 Properly placing a bubble in the US Map, I think perhaps the GeoJSON is pre-projected so I'm using two different projections, one for the map and one for the circles. Ideally I think I would find a different GeoJSON that didn't cause this problem, but I think the one I'm using from https://martinjc.github.io/UK-GeoJSON/ is the only one available.
So my question is, is there a sensible method for figuring out what projection this map is, in order that I can use the same projection for the circles?
...ANSWER
Answered 2020-Oct-24 at 15:54I have some bad news for you, the actual reason the points are wrong is that you're missing a minus sign in front of the latitude. Ayr has a latitude of -4.6, not 4.6. Just adding a -
in front of the points fixed it for me.

QUESTION
I am trying to display a floorplan to my webapp using d3.js and vue js. The data comes from a .json file and is in a geojson format. I generated some test data from this geojson website. I was thinking I could use the d3.js path function to plot each different object to a svg element. Would this be the correct way to go about doing this? I have looked at this tutorial to make a united states map from geojson data. I was thinking this would be the right way to do it if you inputted different data. However my program spits out random rectangles to the webapp. I think this may be becauseof the projection I am using but Im not sure. I havent used d3.js like this before so its all new to me. I included my code in below. Any help is greatly appreciated and im open to possibly using a different java script library but d3js is preferred.
...ANSWER
Answered 2020-Jul-22 at 05:10My apologies, I mislead you when commenting on your last question. I read the code and saw an obvious issue - but missed the reference to a floor plan - which for the coordinates given was unlikely to be measured in latitude/longitude pairs. The answer below would be appropriate for a floor plan in lat/long pairs (as would be exported from geojson.io and because projection is less relevant at the building scale) or a geojson floor plan with coordinates in meters/feet.
Geojson in an arbitrary Cartesian coordinate system
You don't have geographic coordinates consisting of latitude/longitude pairs measured in degrees (as I thought when commenting), you have coordinates consisting of x,y values measured in some unit like metres or feet.
To project these corodinates we do not want to use d3.geoSomeProjection
because these project latitude/longitude pairs on a sphere to a 2d plane. Nor do we want to use a null projection (the default projection for d3.geoPath) because that treats geojson coordinates as pixel coordinates (we can use a null projection when the coordinates in the geojson have been already been converted to pixel values - we know we don't want a null projection here because we have negative values).
Instead we can use d3.geoIdentity
(the geo
prefix indicates it is just part of the geo
module of D3 but it doesn't require geographic coordinates). This "projection" allows us to apply some projection methods to the data, namely .center()
or .scale()
. D3 also has two convenience methods that set both simultaneously: fitExtent and fitSize which stretch and translate specified geojson to given dimensions:

Using the guide_legend
argument, even without specifiying any further arguments, changes my legend from a continuous legend to a discrete one.
I need to correct this (e.g. to use this: Add a box for the NA values to the ggplot legend for a continous map and then order the legends.)

The right command here would be guide_colorbar()

QUESTION
I am writing a script to go to the NYT website on Corona, get the US data, extract numbers (total, death), and to send me a notification. I am close, but when I extract numbers and display them, they are put together (ie 700021 instead of 7000,21). My question is:
How do I extract the numbers so that they are delineated?
Here is the code:
...ANSWER
Answered 2020-Mar-18 at 22:29You are getting a list of numbers from the returnNumbersInString
handler, but just coercing the list to text doesn't normally provide any kind of formatting. One solution would be to use text item delimiters
to specify the text to use when joining the list items. For example, when converting to text for the notification you could do something like:
