heatmap

问题 I have this heatplot that I've generated using ggplot2. What I would like to do is to add white space between the variables listed in capital letters and the variables listed in lower case letters so as to separate these two categories. I still want the tiles to be of equal width. The code I've used to generate the plot is: ggplot(mockdata, aes(variable, Measurement)) + geom_tile(aes(fill = mockdata$plotval), colour = "dark red") + scale_fill_gradient2(limits=c(-20, 20),high = "firebrick3",

问题 Android SDK 2.3.3 Google Maps V2 Currently I'm drawing circles overlays and adding them to a MapView. The size is dictated by a certain value and I'm looking to determine the RadialGradient color of the circle by something else. circle.setShader(new RadialGradient(pt.x, pt.y, 40, Color.argb(150, 252, 5, 5), Color.argb(60, 234, 231, 0), TileMode.MIRROR)); canvas.drawCircle(pt.x, pt.y, radius, circle); It works, however I'd prefer the edges to look more similar to the classic heatpoint map.

What is the best suggested approach for graphically displaying this on a

问题 I want to plot a heatmap of fold changes in matplotlib, where the colors are plotted on a log2 scale, and customize which ticks are shown in the colorbar. I tried the following: import matplotlib.pylab as plt import numpy as np import matplotlib.colors from matplotlib.colors import SymLogNorm, LogNorm mat1 = np.clip(np.random.normal(20, 10, [20, 20]), a_min=0, a_max=500) mat2 = np.clip(np.random.normal(10, 5, [20, 20]), a_min=0, a_max=500) mat = np.clip(mat1 / mat2, a_min=0, a_max=500) plt

问题 I use an heatmap to visualize a confusion matrix. I like the standard colors, but I would like to have 0s in light orange and highest values in dark purple. I managed to do so only with another set of colors (light to dark violet), setting: colormap = sns.cubehelix_palette(as_cmap=True) ax = sns.heatmap(cm_prob, annot=False, fmt=".3f", xticklabels=print_categories, yticklabels=print_categories, vmin=-0.05, cmap=colormap) But I want to keep these standard ones. This is my code and the image I

问题 I am trying to take my dataset which is made up of protein dna interaction, cluster the data and generate a heatmap that displays the resulting data such that the data looks clustered with the clusters lining up on the diagonal. I am able to cluster the data and generate a dendrogram of that data however when I generate the heatmap of the data using the heatmap function in R, the clusters are not visible. If you look at the first 2 images one is of the dendrogram I am able to generate, the

问题 I've made a heatmap in R using heatmap.2 and the only thing I can't figure out is how to control the presence and labeling of tick marks on the color key. I have an example below. What I would like to do is have tick marks at the beginning and end of the color key to indicate the range of values (in this case 0-1), rather than 6 tick marks with labels at 0, 0.4 and 0.8. I'm sure there is a simple way to control this but I can't seem to find it. library('gplots') data <- c(0, 0.1, 0.1, 0.2, 0
