Adding errorbars in ggplot Python

阅读更多关于 Adding errorbars in ggplot Python

问题 Can't find a way of adding errorbars to a Python ggplot plot. The following issue has been neglected for over a year. Nothing in the docs. 回答1: I had this same problem and found no solution. However I did find a way around it. You can use matplotlib in the style of ggplot. From there it's much easier to use error bars. I've attached an example of some code I used. plt.style.use('ggplot') This is an extract of one of my codes df2.gLongCrFiltered['mean'].plot(kind='bar', yerr=df2

Accessing axis or figure in python ggplot

阅读更多关于 Accessing axis or figure in python ggplot

问题 python ggplot is great, but still new, and I find the need to fallback on traditional matplotlib techniques to modify my plots. But I'm not sure how to either pass an axis instance to ggplot, or get one back from it. So let's say I build a plot like so: import ggplot as gp (explicit import) p = gp.ggplot(gp.aes(x='basesalary', y='compensation'), data = df) p + gp.geom_histogram(binwidth = 10000) No problems so far. But now let's say I want the y-axis in log scale. I'd like to be able to do

Is it possible to plot multiline chart on Python ggplot?

问题 I need to plot 3 columns of a Pandas dataframe on python ggplot, with the same index. Is that possible? Thank you 回答1: I'm assuming you want something in ggplot that replicates something like this in matplotlib. import pandas as pd df = pd.DataFrame({'a': range(10), 'b': range(5,15), 'c': range(7,17)}) df.plot() ggplot expects the data to be in 'long' format, so you need to do a little reshaping, with melt . It also currently does not support plotting the index, so that needs to made into a

when I tried to plot a timeseries with ggplot, the x axis lables became too crowded and overlapped each other: The code is: plot = ggplot(df, aes(x=df.index, weight='COUNT')) + \ geom_bar() + \ xlab('Date') + \ ylab('Incidents') I tried to add the following line + theme(axis.text.x = element_text(angle = 90, hjust = 1)) to the plot, but it doesn't work. And this extra line gives me error: SyntaxError: keyword can't be an expression close failed in file object destructor: sys.excepthook is missing lost sys.stderr Any idea how this happened and how should I fix it? Thanks!! (Old question,
