问题 Is it possible to automatically generate multiple subplots in matplotlib? An example of the process I want to automate is: import matplotlib.pyplot as plt figure = plt.figure() ax1 = figure.add_subplot(2, 3, 1) ax2 = figure.add_subplot(2, 3, 2) ax3 = figure.add_subplot(2, 3, 3) ax4 = figure.add_subplot(2, 3, 4) ax5 = figure.add_subplot(2, 3, 5) ax6 = figure.add_subplot(2, 3, 6) The subplots need unique names, as this will allow me to do stuff like: for ax in [ax1, ax2, ax3, ax4, ax5, ax6]: ax

问题 Say I have this dataframe: Type Cat1 Cat2 Cat3 0 A 0.384000 0.393000 0.458000 1 B 0.603337 0.381470 0.299773 2 C 0.585797 0.452570 0.317607 3 D 0.324715 0.765212 0.717755 That I plot like this (from here): axes = df.set_index('Type').plot.bar(subplots=True, legend=False) plt.subplots_adjust(hspace=0.35) My problem: how can I set a different ylim for each subplot? And how can I modify things like the font size of the Cat titles? 回答1: the plotting method returns an array of axes in your axes

How can I programmatically select a specific subplot in Matplotlib?

问题 So in a figure where three vertical subplots have been added with add_subplot, how can I select let's say the middle one? Right now I do this list comprehension: [r[0] for r in sorted([[ax, ax.get_geometry()[2]] for ax in self.figure.get_axes()], key=itemgetter(1))] where I can simply select the index I want, with the corresponding axes . Is there a more straightforward way of doing this? 回答1: From the matplotlib documentation: If the figure already has a subplot with key (args, kwargs) then

How to manually position one subplot graph in matplotlib.pyplot

How do I reposition the graph in the second row such that it is center aligned with respect to the WHOLE figure. On a more general note how to manually reposition the graph anywhere in the same row? import matplotlib.pyplot as plt m=0 for i in range(0,2): for j in range(0,2): if m <= 2: ax = plt.subplot2grid((2,2), (i,j)) ax.plot(range(0,10),range(0,10)) m = m+1 plt.show() Thank you. Using GridSpec , you can create a grid of any dimension that can be used for subplot placement. import matplotlib.gridspec as gridspec import matplotlib.pyplot as plt gs = gridspec.GridSpec(4, 4) ax1 = plt.subplot

问题 I have variables x and y def function(a,b): x = x[(x>a)*(x<b)] y = y[(y<a)*(y>b)] # perform some fitting routine using curve_fit on x and y fig = plt.figure() ax = fig.add_subplot(111) phist,xedge,yedge,img = ax.hist2d(x,y,bins=20,norm=LogNorm()) im = ax.imshow(phist,cmap=plt.cm.jet,norm=LogNorm(),aspect='auto') fig.colorbar(im,ax=ax) fig.show() All works fine. But I have 6 pairs of different input parameters a and b . I would like to somehow call function(a,b) using a loop and plot the six

How to remove duplicate legend entries w/ plotly subplots()

问题 How can I remove the duplicates in my legend when using plotly's subplots()? Here is my MWE: library(plotly) library(ggplot2) library(tidyr) mpg %>% group_by(class) %>% do(p = plot_ly(., x = ~cyl, y = ~displ, color = ~trans, type = 'bar')) %>% subplot(nrows = 2, shareX = TRUE, titleX = TRUE) %>% layout(barmode = 'stack') 回答1: Another workaround using the tidyverse . The following steps are added to the original MWE: Convert the trans column to a factor. Use tidyr's complete to fill (non-NA)

问题 I am plotting two subplots that share the same x-axis but when I plot I only see the x-axis ticks on the second subplot. How can I make the x-ticks visible on both subplots? Also I would like to set y-labels for both subplots but only the second is visible. Can you please help in displaying the y-label on both subplots?

问题 I have problem to set the position of subplots. I'm using subplot inside a loop. But when I try to make special position to the subplots it doesn't work. This is my code: h=subplot(2,2,3); set(h,'position',[0.15 0.15 0.4 0.4]); plot(d3,S3,'*','Color',colors(i,:)); I tried different methods but can't see the third subplot, and sometimes the plot shows only one iteration. How can I fix this? 回答1: This create 3 subplots. Position is [left bottom width height]). I usually try to make sure that
