heatmap

I can create and n by n heatmap using the following code, for example let n be 10: random_matrix = np.random.rand(10,10) number = 10 incrmnt = 1.0 x = list(range(1,number +1)) plt.pcolormesh(x, x, random_matrix) plt.colorbar() plt.xlim(1, number) plt.xlabel('Number 1') plt.ylim(1, number) plt.ylabel('Number 2') plt.tick_params( axis = 'both', which = 'both', bottom = 'off', top = 'off', labelbottom = 'off', right = 'off', left = 'off', labelleft = 'off') I would like to add a 2 row heatmap one near each of the x and y axis, from say row1 = np.random.rand(1,10) and col1 = np.random.rand(1,10) .

I have a set of 3-tuples, each 3-tuple consists of (var1, var2, result). Example of a list of 9 3-tuples: <type 'list'>: [(4, 0.7, 0.8530612244898, 0.016579670213527985), (4, 0.6, 0.8730158730157779, 0.011562402525241757), (6, 0.8, 0.8378684807257778, 0.018175985875060037), (4, 0.8, 0.8605442176870833, 0.015586992159716321), (2, 0.8, 0.8537414965986667, 0.0034013605443334316), (2, 0.7, 0.843537414966, 0.006802721088333352), (6, 0.6, 0.8480725623582223, 0.01696896774039503), (2, 0.6, 0.84693877551025, 0.010204081632749995), (6, 0.7, 0.8577097505669444, 0.019873637350220318)] Now I'd like to

I'm trying to plot a heatmap using R 's plotly package, where I'd like to have specific colors to specific labels of the y-axis tick text. Here's an example dataset: set.seed(1) df <- reshape2::melt(matrix(rnorm(100),10,10,dimnames = list(paste0("G",1:10),paste0("S",1:10)))) And here's what I'm trying: library(plotly) library(dplyr) plot_ly(z=c(df$value),x=df$Var2,y=df$Var1,colors=grDevices::colorRamp(c("darkblue","gray","darkred")),type="heatmap",colorbar=list(title="Scaled Value",len=0.4)) %>% layout(yaxis=list(title=list(color=c(rep("darkred",5),rep("darkblue",5))))) It's not working since

I need to generate the heat map of a object based on its position example: the detected green ball in a video frame . If it stays in a position for a long duration then that place should be red and the positions in the frame where the ball has passes for a short duration must be in blue in that way i need to generate a heat map . Thanks in advance Well what you can do here is 1) First define a heatmap as the size of the image heatmap = np.zeros_like(img[:,:,0]).astype(np.float) 2) Since you already have the detected object and its position, in the heatmap, add 1 to all pixels in the bounding

I am very new to R and recently I have been playing around with the pheatmap library to generate, well, heatmaps. My problem is that I want to color my heatmap in a specific way. I'll describe below: Values < 1 should be a color ramp (e.g. dark blue to light blue) A value exactly equal to 1 should be dark grey Values > 1 should be a color ramp (e.g. dark red to light red) I have played around with the breaks parameter and the color parameter with various palettes but I can't seem to nail a good solution. the closest I've come is something like this: pheatmap(mtx, color = c('#4444FF','#F4FF4F',
