It is designed for python and has the ipython kernel.

QUESTION
I want to create a timeline plot that roughly resembles the example below: lots of overlap at some points, not a lot of overlap at others.
What I need: overlapping images should repel each other where necessary, eliminating or reducing overlap. Ideally I'd be able to implement either a vertical or horizontal repel.
...ANSWER
Answered 2021-Oct-30 at 11:01Here is the solution I’ve been able to come up with, repurposing the circleRepelLayout
function from the awesome packcircles
package
into the repel_vector
vector function that takes in your overlapping vector and a "repel_radius", and returns, if possible, a non-overlapping version.
I demonstrate the solution with the richtext
geom since this is a geom I’ve always wished had repel functionality.

ANSWER
Answered 2021-May-20 at 11:50I'm not sure your issue is a date issue, as I couldn't get the image on the plot using layout.image
, even when I used 1:7
instead of the dates, but then again I'm not a plotly expert.
That said, I'm sure there are a few methods to get the image on the plot without using geom_image
, here's one way which is not very clean - and could be inefficient with big dataframes- but it works with plotly:
QUESTION
I'm trying to build a visualisation with both drawn shapes (e.g. using geom_circle) and images. In both cases, I want to be able to position them on the page specifically with coordinates, rather than using one of the built in chart types.
See update further down...
However, I can either get the circles with the correct aspect ratio (i.e. round not oval) or the images, but not both. In the example below, you can see the image is not shown as square when it is.
I have tried various things including coord_fixed, scale_size_identity and coord_cartesian, but to no avail. The overall output will be landscape, which is why I have set the cartesian limits as I have.
This is a simplified version. In the full version, I'll get the coordinates from the data (which I'm fine with).
...ANSWER
Answered 2021-Feb-14 at 10:43I strongly feel you may have seen this thread: Can geom_image() from the ggimage package be made to preserve the image aspect ratio? - this was asked and answered by ggplot2 gurus such as Claus Wilke, Baptiste and Marco Sandri - it seems that ggimage is scaling to the device. Thus if you would like a square, you need to save to a device of square dimensions. Or, if you don't have a square image, of course, dimensions relative to your image used.
I used see::geom_point2
(no weird border), because I got the strong feeling that you have not used ggforce::geom_circle
. Also mild changes where I added the aes
call.
QUESTION
Trying to make it so that I can add the bars on one by one for a bar chart in R. I know that there is a function called transition_layers, but haven't been able to make it work for the life of me. In the reproducible example below I have the bar moving over the years, but what I want is a new bar added one by one over the years and for each older bar to stay.

...ANSWER
Answered 2021-Jan-14 at 12:58You need to explicitly tell gganimate
that each column in the x-axis is in a different group by setting group=Year
inside geom_col
(I changed geom_bar
to geom_col
because I think it is more intuitive, but it is basically the same thing). Otherwise, gganimate will treat all of them as the same group and the column will slide through the x-axis. This has happened to me before with other types of animations. Explicitly setting the group
parameter is generally a good idea.
QUESTION
I am trying to use images (e.g. country flags) in a ggraph network. I was looking to use ggimage's geom_image
, however I reckon that the function needs to be adapted to work with ggraph where we do not specify the x and y coordinates.
ANSWER
Answered 2020-Dec-27 at 16:34It's true that ggraph
does not require you to specify X and Y coordinates, but this is a convenience. The variable names are x
and y
. You can be explicit:
QUESTION
I am new on learning HTMl coding, and I wanted to train my self by rproducing the https://www.google.com/ page. Thus, I've added inputs to let the user making is researches.
There are two different types of reshearches I want to provide (jus as like in the Google's page). In the first one, by clicking on the "Google Search" submit input, the user is doing a classic research. While in the second one, when the user clicks on the "I'm Feeling Lucky" submit input, the user is directly taken to the first link that would have appeared if the ser would have done a classic research.
But the problem is that both of the two submit inputs are giving me a "classic research"and after looking for many answers in this forum, and also other ones, I still don't understand why does my html code doesn't work:

Answered 2020-May-26 at 02:08You didn't provide any of your data nor did you specify where or how you want the image to be placed so I can't reproduce your plot. However, you should be able to do what you want to do with cowplot. For example:
