scatter-plot

问题 I am trying to draw some objects with the fabulous Matplotlib package for Python. These objects consist of points implemented with plt.scatter() and patches implemented with Poly3DCollection . I would like to have the patches with a slight transparency so that the points and edges behind the patches can be seen. Here the code and plot I already generated. Seems I am almost there, just missing the feature of transparency. Interestingly, if I first plot the Ploy3DCollection and afterwards the

问题 What I want is to display 2 figures next to each other in one row, so that the first one is square and the second one takes all the remaining width, it should be wider than the first one (I use knitr and LaTeX). I tried using r layout and specify out.width and out.height in a figure chunk options, but I could not get it right and I'm not sure this is the right approach. And in general, it is better to configure figure size in chunk options, right? But what's the best approach for more complex

问题 I am using CorePlot for Scatter plot and would like to know how to obtain the circles of the scatter plot with such a color effect as it is here http://i.stack.imgur.com/7ZcqY.jpg I would like to get the color as in CPTXYScatterPlot - Can I set the Z order of plot symbols?. 回答1: In your symbolForScatterPlot implementation, create a circlePlotSymbol with a gradient fill, like so: CPTPlotSymbol *circlePlotSymbol = [CPTPlotSymbol ellipsePlotSymbol]; // Obviously for a real bubble chart you'll

问题 Situation: Scatter points/date, each month could contain a variable-number of data (points). Desired: Have fixed-width months along x-axis whose columns contain their respective points (i.e. same-number of points/month). Can Core-Plot extrapolate missing data points to equalize the distribution of data/month? How would that be done? I want the fixed-width months to coincide/sync with their respective data points (and hence, may necessitate the filling in of missing data points; i.e., months

问题 I need to plot a cell array with the following format in Matlab: {[vector1], [vector2], ...} Into a 2D graph with the index of the vector as the y and the vector as the x ([vector1], 1), ([vector2], 2), ... 回答1: Here's a simple option: % some arbitrary data: CellData = {rand(10,1)*50,rand(10,1)*50,rand(10,1)*50}; % Define x and y: x = cell2mat(CellData); y = ones(size(x,1),1)*(1:size(x,2)); % plot: plot(x,y,'o') ylim([0 size(x,2)+1]) so you plot each vector of x on a separate y value: It will

问题 I'm currently attempting to generate a 3d scatterplot for my project. As you can see below I've subset the species column into three different subsets to seperate out the three species. I'm managing to generate the scatterplot fine with one of the three data sets but I'm having problems adding points to the existing scatterplot from the other two data sets. Is there something I'm doing wrong or something I'm missing? Thanks in advance Brooke Data: Species Mid_X Mid_Y Mid_Z Cod -226.483 290
