legend

I need to make multiple contours plots of several variables on the same page. I can do this with MATLAB (see below for MATLAB code). I cannot get matplotlib to show multiple legends. Any help would be much appreciated. Python code: import numpy as np from matplotlib import cm as cm from matplotlib import pyplot as plt delta = 0.25 x = np.arange(-3.0, 3.0, delta) y = np.arange(-2.0, 2.0, delta) X, Y = np.meshgrid(x, y) Z1 = X*np.exp(-X**2-Y**2) Z2 = Y*np.exp(-X**2-Y**2) plt.figure() CS = plt.contour(X, Y, Z1, colors='k') plt.clabel(CS, inline=1, fontsize=10) CS = plt.contour(X, Y, Z2, colors='r

I have some data points, and I want to single out some of the points in my visualization. I would do it like this: df = data.frame( x = 1:4, y = 1:4, special = c('normal', 'normal', 'normal', 'special') ) ggplot(df) + geom_point(aes(x, y, color = special)) + scale_color_manual(values = c('red', 'black')) + labs(color = "") + theme_bw() My issue here is that the black points are very self explanatory and don't need a label. I want just the red "special" label to appear. Is there a way I can hide the "normal" label? If you are open to having any color other than red: ggplot(df) + geom_point(aes

I'm new to Leaflet/JavaScript and have been struggling to get legends a map to show only when a specific layers is selected from the layer control. I have three layers, one of which I would like to have no legend and two others that have a corresponding legend. I came across an example, but have not been able to make it work: // Add and remove legend from layers map.on('overlayadd', function (eventLayer) { // Switch to the Permafrost legend... if (eventLayer.name === 'Permafrost') { this.removeControl(legend1); legend2.addTo(this); } else { // Or switch to the treeline legend... this

My question combines two separate issues posted on before on Stackoverflow: i. Adding multiple legends to ggplot and ii. Add line legend to geom_sf . I would like to add multiple legends to ggplot2 (as in the first post), but am using sf . This complicates filling up the aesthetic space. The answer suggested in i. above does not work well with multiple types of geometries -- we cannot assign points and lines to a single class and then use factors. In my case, I have several line and point shapefiles, and simply want to add a separate legend entry for each shapefile added. There seems to be no
