legend

I think cex doesn't work. Cex will change the whole scale of the legend. But I just want to enlarge the text size. any command will help? Yes!, set pt.cex = 1 and change cex as you want as in: plot(c(1,1)) legend("topleft", "Legend", cex=1.3, pch=1, pt.cex = 1) You can set the cex for the points separately from the rest of the legend. This would still make the box small, though. A more specific example of what you're trying to do might help. However, see if this solves your problem: plot(rnorm(10)) legend("top", legend="test", pch=21) #everything is normal sized (cex=1 default from par())

I want to plot two functions in different colors and point styles with a corresponding legend, in plain R . I have several questions: I am using pch=21 and pch=22 . My understanding is that they are "filled" symbols. They do appear filled as expected in the legend, but they appear hollow on the graph itself. What's wrong? Can I get more space between the points without specifying a grid manually? maybe by selecting the number of points to be printed? Feel free to add any kind of advice you'd like. I'm very new to R. In particular, is there a better way to plot two functions? e.g. by defining

I have a plot with a horizontal legend: legend("bottomleft", inset = c(0, -0.3), bty = "n", x.intersp=0, xjust=0,yjust=0, legend=c("AAPL", "Information Technology", "Technology Hardware and Equipment", "S&P 500"), col=c("black", "red", "blue3", "olivedrab3"), lwd=2, cex = 0.5, xpd = TRUE, ncol = 4) The problem is that there is a huge spacing between the first item of the legend, "AAPL", and the second item "Information Technology". I tried adjusting the spacing using txt.width() , but it didn't work at all. Or maybe I am not using this option as directed. This is how I have introduced the txt

I have a pandas DataFrame and I want to plot a bar chart that includes a legend. import pylab as pl from pandas import * x = DataFrame({"Alpha": Series({1: 1, 2: 3, 3:2.5}), "Beta": Series({1: 2, 2: 2, 3:3.5})}) If I call plot directly, then it puts the legend above the plot: x.plot(kind="bar") If I turn of the legend in the plot and try to add it later, then it doesn't retain the colors associated with the two columns in the DataFrame (see below): x.plot(kind="bar", legend=False) l = pl.legend(('Alpha','Beta'), loc='best') What's the right way to include a legend in a matplotlib plot from a

Using the legend() function is it possible to have the point and line be different colors? I feel like I'm missing something fairly obvious. The pt.bg option can change the background color, but I'm not seeing a pt.fg option The arises in the case when you use the lines() and points() command separately with different colors and want the legend to represent what is plotted. I thought it might be possible with the merge options, but I clearly don't quite understand what that is for. Example: plot( 0, type="n", xlim=c(0,5), ylim=c(0,5) ) A <- matrix( c( c(1,2,3,4), c(2,1,2,4)), ncol=2 ) B <-

I try to solve this problem several times and give up. Now, when I have met him again, I decided to ask for some help. I have this code for my Legend: legend: { layout: 'vertical', align: 'right', verticalAlign: 'top', x: -10, y: 100, borderWidth: 0, labelFormatter: function() { if(this.name!='Series 1') { return this.name; } else { return 'Legend'; } } } If I change the return from 'Legend' to '' the text is not shown but still there is a 'dash' on the top of the legend. If I do not use label formater function I have 'Series 1' + 'dash' like a first row in my legend. How to hide them? Please,

I currently am plotting a stacked bar graph of a large amount of taxonomic data, and only wish to show significant species in the legend (out of ~500 I wish to show ~25). Is there a simple way to do this? Below is the code I have: labels=['0','20','40','60','80','100','120'] ax1=subj1df.plot(kind='barh', stacked=True,legend=True,cmap='Paired', grid=False) legend(ncol=2,loc=2, bbox_to_anchor=(1.05, 1), borderaxespad=0.) label1=['Baseline','8h','24h','48h','96h','120h'] ax1.set_yticklabels(label1, fontdict=None, minor=False) plt.title('Subject 1 Phyla',fontweight='bold') plt.savefig(

I have a graph whose left upper corner is quite blank. So I decide to put my legend box there. However, I find the items in legend are very small and the legend box itself is also quite small . By "small", I mean something like this How can I make the items ( not texts! ) in the legend box bigger? How can i make the box itself bigger? To control the padding inside the legend (effectively making the legend box bigger) use the borderpad kwarg. For example, here's the default: import matplotlib.pyplot as plt import numpy as np x = np.linspace(0, 10, 100) fig, ax = plt.subplots() for i in range(1,
