plotly

问题 I am working on creating basketball shot charts in R using the library plotly, although I am currently stuck. For reference, the type of graph I'm creating will hopefully look a bit like this when they're complete: From a plotly perspective, I need to use a trace type that will allow me to place hexagons (or some other shape) on the entire graph. I'm confident that I'll be able to appropriately tune the color and size parameters of the hexagons to account for which hexagons should be red vs.

问题 I am fairly new to python and ploty (<3 months of actual coding at this point). I am trying to create subplots in plotly. I have created graphs in plotly using the code below(code snippets attached below as well), but I can't seem to get them to work using subplots I create many of these types of data graphs and any help in tightening my code would be much appreciated. Here is a sample dataset (below is the only way I know how to line it up on this site??) [NOTE: it is not the exact same

问题 I am trying to resize a plotlyOutput in a shiny app but changing the height parameters doesnt seem to affect the plot size, after updating today to R 3.4 and updating shiny, and plotly (plotly_4.7.0, ggplot2_2.2.1.9000, shiny_1.0.3 ) I realized that the size of the plot does not change dynamically when resizing the window. I have tried modifying the size of the plot directly using height in plotlyoutput, as well as modifying the $layout$height property from the plotly object,t but it doesnt

问题 I am new to programming. I am only fairly experienced with R. I am struggling to generate a large table where cell contents would expand from hovering mouse cursor on a relevant cell. This is similar to the proposed in this other question: Show a tooltip or popover in Shiny datatables for each cell? However in this other example two tables are used, where Table 2 as a reference for tooltip cell content, and both are shown. I'd like to have just one table showing, thus making a large table

问题 Is there a way to change the legend size in plotly for R? I have not come across this option. I have looked at the docs on legends, https://plot.ly/r/legend/, but it does not mention this. 回答1: Use layout(legend = list(font = list(size(30)))) : plot_ly(data = mtcars, x = as.character(mtcars$cyl), y = mtcars$mpg, type = "box", color = as.character(mtcars$cyl)) %>% layout(showlegend = TRUE, legend = list(font = list(size = 30))) 来源： https://stackoverflow.com/questions/37245004/change-legend

问题 I have a shiny app like the following: server.R : shinyServer(function(input, output) { output$trendPlot <- renderPlotly({ plot_ly(movies, x = length, y=rating, mode='markers', color=as.factor(year), colors = c("#132B43", "#56B1F7")) -> plott plott }) }) ui.R : library(shiny) library(plotly) library(ggplot2movies) # Needed for the 'movies' data set shinyUI(fluidPage( titlePanel("Movie Ratings!"), mainPanel( plotlyOutput("trendPlot") ) )) This produces a warning: Warning in RColorBrewer:

问题 How can I left-align the chart title in a plot_ly object (as created from ggplotly )? library(ggplot2) library(plotly) p <- ggplot(mtcars, aes(mpg, cyl)) + geom_point() + ggtitle("My Title") + # Not necessary by default: theme(plot.title = element_text(hjust = 0.0)) p ggplotly(p) Output of p (intended title alignment): ggplotly(p) (title alignment not preserved): 回答1: You could do ggplotly(p) %>% add_annotations( yref="paper", xref="paper", y=1.15, x=0, text="My Title", showarrow=F, font=list

问题 I'm using plotly::ggplotly() and I need the user to be able to both select a single point and to select multiple points with brushing. I want both selection options to exist in parallel. The user should be able to click on a point and to lasso select several points, and both of those pieces of information should be recorded. The problem I'm having is that if I click on a point, then the lasso selection gets reset. But the opposite is not true: if I lasso select and then click on a point, then

问题 I am using plotly.js to plot graph in my web app. The modeBar is placed at top right corner by default. Is there any way I can place it at the top center? 回答1: This should work: .js-plotly-plot .plotly .modebar { left: 50%; transform: translateX(-50%); } 回答2: .js-plotly-plot .plotly .modebar{left: 40%} 来源： https://stackoverflow.com/questions/45173726/place-the-modebar-at-top-center-using-plotly-js

问题 I'm trying to customize some subplots, but I don't understand what the axis 'anchor' attribute means. Some examples where this attribute is used are here: https://plot.ly/javascript/subplots/ . What does yaxis2: {anchor: 'x2'} mean? What does anchor=false , or anchor=free mean? I haven't been able to find an explanation in the online docs. 回答1: To answer my own question, I found the documentation on the axis anchor attribute here. An x axis can be anchored to a y axis, for example xaxis2:
