I am attempting to generate map overlay images that would assist in identifying hot-spots, that is areas on the map that have high density of data points. None of the approaches that I've tried are ...

I would like to use Matplotlib to generate a scatter plot with a huge amount of data (about 3 million points). Actually I've 3 vectors with the same dimension and I use to plot in the following way. ...

I want to use a color map for my matplotlib heat map. I tried doing this: myHeatMap.imshow(heatMap, extent=ext, cmap=get_cmap(cm.datad["Spectral"])) However, the Python interpreter ...

My question is almost exactly similar to this one. However, I'm not satisfied with the answers, because I want to generate an actual heatmap, without explicitely binning the data. To be precise, I ...

I'm trying to use matplotlib to plot 3D heatmap with results of my simulations. I've read this topic and tried to use imshow. Unfortunately, when I save the figure in SVG or EPS formats, it converts ...

Given some data in three lists, for example: latitudes = [50.877979278564,48.550216674805,47.606079101562,50.772491455078,42.451354980469,43.074657440186,44.044174194336,44.563243865967,52....

I'm trying to learn how to do a heatmap in Python using matplotlib. I'm going to be plotting a series of locations in a huge X,Y grid based off of an array of tuples. I found this code example which ...

How can one create a heatmap from a 2D scatterplot data in Python, where for each (x,y) point in the scatterplot one has a z value associated to it? The z value will be the value used to color the ...

I am trying to plot a heat map. The data that I use has Geo coordinates and time in seconds. The nature of data is edges encounter each other at certain geo location and spend some time connected. ...

I am trying to generate heat map, or probability map, for Whole Slide Images (WSIs) using probability values. I have coordinate points (which determine areas on the WSIs) and corresponding probability ...

I recently stumbled upon a similar question about how to generate a heatmap of frequencies in Python using the MatPlotLib module. This post was very useful and I could get the individual scripts to ...

I have two lists, x and y, that I wish to plot together in a scatter plot. The lists contain too many data points. I would like a graph with much less points. I cannot crop or trim these lists, I ...

I am interested in constructing a sunflower scatter plot (as depicted in, for example, http://www.jstatsoft.org/v08/i03/paper [PDF link]). Before I write my own implementation, does anyone know of an ...

I have a set of (x, y) data points, and each point has an attached value to it. I'd like to create a heatmap that uses the attached value to determine color, and uses color intensity/transparency to ...

I want to produce a heatmap image akin to the one in this answer. The difference is that I want to do it from a 2d array of values between 0 and 1. What I have tried: def generate_x_y_vectors(...
