kandi X-RAY | graphs Summary

graphs is a C++ library typically used in User Interface, WebGL, Example Codes applications. graphs has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

In mathematics and computer science, graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of vertices or nodes or points and edges or arcs or lines that connect them. A graph may be undirected, meaning that there is no distinction between the two vertices associated with each edge, or its edges may be directed from one vertex to another. Graphs are one of the prime objects of study in discrete mathematics. You can read about this here:

So, this is a good opportunity to use purrr::map. You are half way there by applying code to one dataframe.

You can take the code that you have written above and put it into a function.

Hatch an area in two colors with `pyplot.fill_between`

Asked 2021-Jun-15 at 14:21

I have a red and a blue area between some graphs. Where the two areas overlap, I want the area to be hatched in red and blue, i.e. red and blue stripes (like in the picture, but blue and red instead of white and red). So I want to pass the two colors by their color code onto the function. Is this possible with matplotlib.pyplot.fill_between? Or how could I do this?

Answered 2021-Jun-15 at 14:21

You need to add the hatch argument to your function call to fill_between

As you have not provided an example, it will look something like this:

Pandoc loading images but not latex files from input subfolder

Asked 2021-Jun-12 at 06:57

I've got a latex document that I publish as a pdf, but I need to share it with reviewers in Word .docx format. I've got some images and a bunch of graphs in tikz format in a separate .tex files in a figures subfolder. I've defined input@path{{figures/}} so that I don't have to put the path into each \input{blah.tex} call. This works just fine when I publish the document as a pdf, but when I try to use pandoc to create the docx I get a [WARNING] Could not load include file error for the .tex files, though the images load fine.

As far as I can tell, pandoc should be able to load files from subfolders and the input@path should set it up (this post discuses how to use pandoc parameters to define the input@path).

I'm sure this is some basic lack of understanding on my part, but here's a minimum non-working example:

ANSWER

Answered 2021-Jun-12 at 06:57

Pandoc does not support the \input@path parameter. You could open a feature request here.

I suggest to use TeX to compile the TikZ packages into proper graphics, e.g. with the method described in this Q&A, then use \renewcommand to change \input to \includegraphics, which pandoc will understand. This will also allow to make use of the --resource-path option.

useState results in shallow copy of initial value

Asked 2021-Jun-11 at 19:43

I would like to pass data (which is saved as a state) to a react component that graphs that data. That graph should also be able to filter the data.

The data is a nested object structured as follows.

ANSWER

Answered 2021-Jun-11 at 19:43

Primitives, such as integers or Strings are passed down by their value, while Object data-types such as arrays are passed down by their reference. Here in your example - data is by passed reference. which makes it mutable.

In React - props should be immutable and top-down. This means that a parent can send whatever prop values it likes to a child, but the child cannot modify its own props. From ReactJS documentation

Whether you declare a component as a function or a class, it must never modify its own props.

One solution is is to pass a copy of your original data object.

Updated Codepen. You're still mutating props - not a good idea but it works.

Edit: JSON.stringify is NOT recommended due to it's issues with dates & non-primitive data types. Other ways to deep clone in JS - How to Deep clone in javascript

QUESTION

python plotly - hovering shows more than one value sometimes

Asked 2021-Jun-11 at 10:24

The Problem

I have a plotly graph (figure) composed of multiple go.Scatter graphs, added to the graph using fig.add_trace().

Some scatters share the same indices, and some don't. When hovering above a connection between two graphs which don't share the same incides I see more than one label.

In the picture you can see an example of this: instead of seeing just the green label or just the blue+red (they compose one unit because they share the same incides), I see both. How can I make it show only one of them?

NOTES:

When hovering above a spot which isn't a connection between two segments, I do get the desired result: green if I'm above green, and blue+red if I'm above blue+red.
I tried changing the hovermode parameter from the default 'x', but couldn't find a mode that works. The closest option was closest, but using it only shoes one color: green or blue or red and not green or blue+red as desired.
When zooming in enough, it shows the desired labels (but making the user zoom in all the time is, of course, not a solution).

The Code ...

You can set the hoverdistance manually. Setting it to 2 pixels should solve the problem for you:

How to print multiple plots using a single renderPlot() function in shiny app?

Asked 2021-Jun-11 at 08:52

I have an app which outputs multiple plots. The app essentially takes some data in a specific form and then splits it and then calculates some proportion tables. It then makes graphs of these various tables. In the app below I am printing out only 'one' plot and it works. The issue comes when I have multiple plots(read below).I did find some answers online on how to do this but I failed to implement them in my code. This is my first shiny app so I am not really able to figure it out.

For other readers here, it seems like this is the implementation being asked about in this question.

The method you are using to try to predict labels works with labels for nodes, not edges. To visualize this, I plotted your example data and colored the plot by your Weight and Label columns (code to produce plot appended below) where Weight is the line thickness of the edge and Label is the color:

In order to use this method, you will need to produce data that looks like this, where each node (denoted by ID) gets exactly one node_label:
