heatmap

问题 I am in the circuit board manufacturing industry, and we measure the temperature at a variety of locations on our circuit boards in an effort to identify if certain components are exceeding their required temperatures. I have some exposure to .js visualization libraries, RStudio and Shiny . I would like to implement this application into an existing R or ShinyDashboard that I am developing. What I would like to accomplish is to have a 2d or 3d image of my circuit board, and a heatmap that

问题 In the R d3heatmap package, is there a way to rotate the x axis label to be 90 degrees (perpendicular to the axis) instead of 45? 回答1: I couldn't find an easy option to pass a rotation value to the function, but you can go into the innards of the d3heatmap package and change the rotation in the javascript code. Run ".libPaths()" in R to find where your R packages and their data are stored. In my case I found the d3heatmap package in '/home/nick/R/x86_64-suse-linux-gnu-library/3.1/d3heatmap/'.

问题 I've created an heat map on Google Maps API for Android. The problem is when I increase zoom, the heat map "looses" radius and the look is not that good. There`s a way to increase radius above 50 (Probably the maximum)? :/ 回答1: From the documentation: Radius: The size of the Gaussian blur applied to the heatmap, expressed in pixels. The default is 20. Must be between 10 and 50. Use the Builder's radius() to set the value when creating the heatmap, or change the value later with setRadius().

问题 I have a dataset generated in this way: aa = linspace(A - 5, A + 5, n_points) bb = linspace(B - 1.5, B + 1.5, n_points) z = [] for a in aa: for b in bb: z.append(cost([a, b])) I would like and head map where z define the color in the point (a,b) . I need this to analyze local minimum. I am using matplotlib but I do not know exactly how to proceed. 回答1: Typically you'd use imshow or pcolormesh for this. For example: import numpy as np import matplotlib.pyplot as plt n_points = 10 aa = np

问题 I have plot quite easily a matrix (thus giving a heatmap) with ggplot like this: test <- data.frame(start1=c(1,1,1,1,2,2,2,3,3,4),start2=c(1,2,3,4,2,3,4,3,4,4),logFC=c(5,5,1,0,8,0,5,2,4,3)) ggplot(test, aes(start1, start2)) + geom_tile(aes(fill = logFC), colour = "gray", size=0.05) + scale_fill_gradientn(colours=c("#0000FF","white","#FF0000"), na.value="#DAD7D3") Since I have only the lower part of the heatmap, it gives this plot: But I would like to rotate the matrix 45 degrees, just like I

问题 I have a working solution but am. I've been using the mtcars data set and trying to color by the "disp" variable as my reproducible example. > library(gplots) > m<-cbind(mtcars[,3],mtcars[,3]) > rownames(m)<-rownames(mtcars) > heatmap.2(x=m,dendrogram="none",trace="none",Colv=FALSE,Rowv=FALSE,cellnote=cbind(rownames(m),rownames(m)),notecol="black") I can always cut out the extra row of the pdf, replace with a representation of the p-value in my actual data set (plotting ratios and p-value is

问题 I am having trouble removing the white lines between tiles in my heat map. Below is my code and picture. Has anyone encountered this before? t <- ggplot(Drug_heatmap_df_final, aes(x=reorder(Drug,Total_Deaths), y=Start_Date, fill=Total_Deaths)) + geom_tile() + labs(title="Heatmap of Total Deaths per month by Drug", x="Drug", y="Month") + theme(plot.title = element_text(hjust=.5)) + scale_y_date(date_breaks="1 year" , labels = date_format("%b-%Y")) + theme(axis.text.x = element_text(size=13))

问题 Below is my dataframe df a b c d 1 0 0 0 0 2 0 0 0 1 3 0 0 0 0 4 0 1 0 0 Here is the code which generated heatmap. It uses the library highcharter in R. hchart(as.matrix(df), "heatmap", hcaes(x = variable, y = name, value = value)) %>% hc_colorAxis(stops = color_stops(2, c("yellow","blue")))%>%hc_size(height = 500) My question is, how can I change color of the values/numbers that are being displayed in the heatmap. OR, how do I remove the values from heatmap? 回答1: You may just change your

问题 Ok so I'm working on implementing a heatmap off of data pulled from a server. I'm basing it on the official Google heatmap api and I've based my code off of their code demos. However, my code doesn't work. Sometimes it displays the heatmaps but more often than not it displays nothing. I've double checked to make sure the data is coming in, so lack of data isn't a problem. I can play makers on the map fine, it just seems that heatmaps, or maybe overlays, dont work properly. mOverlay and
