graph

问题 I want to plot a graph, where one node for each document exists and then other nodes for each word in it. This way I want to visualize words, that are occuring in multiple documents. Unfortunately the labels for the nodes overlap, so that they aren't very readable oftentimes. I have tried to increase and decrease the k variable, but it is not really helping. I noticed that the graph changes if its plotted again, and sometimes the labels are more readable, but its not very helpful because I

问题 Problem Statement: Given a matrix of people(denoted by small alphabets) and bikes(denoted by capital alphabets), find the nearest bike for a given person. How will you change your solution if you have to find bikes for a set of people? (assuming multiple bikes can be at the same distance from 1 person)? I know Dijkstra's algorithm and Bellman Ford's algorithm, but curious about the implementation here. Or can it be solved by BFS(Breadth First Search)? 回答1: To assign a single bike to a single

问题 I am trying to adjust the y-axis of this graph so that it starts at 1 instead of 0. What's the best way to do this? The solution offered here cuts off the bottom of the graph. I would like for the bars to look pretty much identical to the graph below, but with the lower y-limit at 1 and each bar moved down 1 unit to match. I would like to preserve the small amount of gray space below each bar. Code: groups %>% ungroup() %>% mutate(message = fct_relevel(message, "Personal", "General"),

问题 I have successfully created a chart with HighChart's HighStock. I'm trying to add vertical lines to the chart. I've searched everywhere in HighStock's docs, Stackoverflow and Google on how to do this, but to no avail. I tried HighStock's "flags" but can't create vertical lines with them. I basically want to turn this chart... ... into something like this: Is this even possible? If yes, how? Thanks! 回答1: Yes, These are called plotLines and are easily added like: xAxis: { plotLines: [{ value:

问题 I am trying to create a bar graph. When I set the limits as (0,7), the bars appear. However, I would like the lower limit to be 1, not 0. When I set the lower limit to 1, the bars do not appear. I get the following error message: Removed 8 rows containing missing values (geom_bar). It doesn't matter how I set the limits. I have used both of the following options: ylim(1, 7) scale_y_continuous(limits = c(1, 7)) Does anyone know how I can fix this? I'd like a graph that looks like this, but

问题 I am using NetworkX and Matplotlib to draw nodes, but the nodes are sometimes being cut off at the edge of the graphic. Is there a setting to increase the margins or prevent them from being cut off? Image: Nodes being cut off at the edge of the graphic Example program: import networkx as nx import matplotlib.pyplot as plt import numpy as np adjacency_matrix = np.array([[1,0,0,0,0,0,1,0],[0,1,1,1,1,0,0,0],[0,1,1,0,0,0,0,0],[0,1,0,1,0,0,0,0], [0,1,0,0,1,1,0,0],[0,0,0,0,1,1,1,1],[1,0,0,0,0,1,1,0
