legend

I am producing four plots using xyplot (lattice) and further combine them with grid.arrange (gridExtra). I would like to obtain a graph with a common global legend. The closest that I have reached is the following. They have to be in a matrix layout, otherwise an option would be to put them in a column and include only a legend for the top or bottom one. # Load packages require(lattice) require(gridExtra) # Generate some values x1<-rnorm(100,10,4) x2<-rnorm(100,10,4) x3<-rnorm(100,10,4) x4<-rnorm(100,10,4) y<-rnorm(100,10,1) cond<-rbinom(100,1,0.5) groups<-sample(c(0:10),100,replace=TRUE)

Hey I am trying to fit a legend onto a plot so that it doesn't obscure the graph. import numpy as np import matplotlib.pyplot as plt X = np.linspace(0,100,11) plt.plot(X,-X, label='plot 1') plt.plot(X,-2*X, label='plot 2') plt.plot(X,-3*X, label='plot 3') leg=plt.legend(ncol=2) leg.get_frame().set_visible(False) plt.show() So in the minimum working example, above, what I want to be able to do is move the 'plot 2' label in the legend into the right column, i.e. directly under 'plot 3'. Any help would be appreciated, thanks. The legend is filling in the columns from left to right. In other words

I plotted some data using scatter plot and specified it as such: plt.scatter(rna.data['x'], rna.data['y'], s=size, c=rna.data['colors'], edgecolors='none') and the rna.data object is a pandas dataframe that is organized such that each row represents a data point ('x' and 'y' represents the coordinate and 'colors' is an integer between 0-5 representing the color of the point). I grouped the data points into six distinct clusters numbered 0-5, and put the cluster number at each cluster's mean coordinates. This outputs the following graph: I was wondering how I can add a legend to this plot

I am using matplotlib In plot() or bar() , we can easily put legend, if we add labels to them. but what if it is a contourf() or imshow() I know there is a colorbar() which can present the color range, but it is not satisfied. I want such a legend which have names(labels). For what I can think of is that, add labels to each element in the matrix, then ,try legend(), to see if it works, but how to add label to the element, like a value?? in my case, the raw data is like: 1,2,3,3,4 2,3,4,4,5 1,1,1,2,2 for example, 1 represents 'grass', 2 represents 'sand', 3 represents 'hill'... and so on.

I want to independently move two legends on a map to save save and make the presentation nicer.

I am working on customizing the layout of a Silverlight Toolkit Chart. I have two requirements: 1) Move the Legend area to the bottom of the chart (solved). 2) change the layout of elements within the legend to be displayed next to each other, ie. {legend 1},{legend 2},{legend 3}, rather than the default column format. 1) was easy to solve with a ControlTemplate (see below). 2) How do I change the layout of legend items? Can it be done by further customizing the Chart's ControlTemplate, or does the Legend need its own ControlTemplate? The Chart itself is defined as: <chartingToolkit:Chart Name
