visualization

问题 As illustrated below, I am looking for an easy way to combine two or more heat-maps into one, i.e., a heat-map with multiple colormaps. The idea is to break each cell into multiple sub-cells. I couldn't find any python library with such a visualization function already implemented. Anybody knows something (at least) close to this? 回答1: The heatmaps can be drawn column by column. White gridlines can mark the cell borders. import numpy as np from matplotlib import pyplot as plt a = np.random

问题 I'm trying to plot a kind of Riemann's surface of a function (I'm not sure if it's the right name for the thing), as shown below: Here's what I tried: r = (0:1:15)'; % create a matrix of complex inputs theta = pi*(-1:0.05:1); z = r*exp(1i*theta); w = z.^(1/2) ; % calculate the complex outputs figure('Name','Graphique complexe','units','normalized','outerposition',[ 0.08 0.1 0.8 0.55]); subplot(121) surf(real(z),imag(z),real(w),imag(w)) % visualize the complex function using surf xlabel('Real

问题 I am new in R . This moment I am going to draw some visualization using ggplot2 (Everything is done). My visualization has an image as a background. When I am going to use renderPlotly on the server and plotlyOutput in UI, but background is always white. If I use renderPlot on the server and plotOutput in UI, it works fine. I really need to use renderPlotly . Also, I tried to use ggplotly . ggplotly(ggplot2_object) but background is still white. Any ideas ? Thanks ! 来源： https://stackoverflow

问题 I am new in R and trying keras in Rstudio . All the accuracy , loss interactive plots by running fit() are appearing in Viewer pane instead of Rmarkdown file. All other plots usually plot inside Rmarkdown files but not with keras. I have also checked Global settings in Rstudio Tools>Global Options>R Markdown>Show output preview in "Window" . How do I make them plot in Rmarkdown instead of Viewer Pane. How do I make this mandatory for all plots to create inside Rmarkdown files only and now in

问题 I am trying to work with plotly, specifically ploty express, to build a few visualizations. One of the things I am building is a scatterplot I have some code below, that produces a nice scatterplot: import plotly.graph_objs as go, pandas as pd, plotly.express as px df = pd.read_csv('iris.csv') fig = px.scatter(df, x='sepal_length', y='sepal_width', color='species', marker_colorscale=px.colors.sequential.Viridis) fig.show() However, I want to try and change the colorscheme, i.e., the colors
