matplotlib: change timestamp format of x-grid in a bar-chart

由 痴心易碎 提交于 2019-12-11 03:15:11
问题 I have the following code: my_df.plot(x='my_timestamp', y='data_count', kind='bar') and the output looks like this: I am wondering is it possible to change the x-grid format, so it will just show 2016-03-14 instead of 2016-03-14 00:00:00 Thanks! 回答1: There might be a more elegant solution, but what definitely works is to loop over the xticklabels, split them up and only use the first part of the string as a new ticklabel. ax = df.plot(x='my_timestamp', y='data_count', kind='bar') ax.set

Using JSON in d3v4 stacked bar chart

由 我们两清 提交于 2019-12-11 02:57:39
问题 I have found a d3v3 stacked bar chart example that I would like to use because it uses json data. There is also a d3v4 canonical bar chart example that loads and uses a csv. I want to make a d3v4 stacked bar chart but I want to use json data to create it rather than load from a csv. I am not sure how to upgrade the v3 version or to modify the v4 version to accomplish this. This is my data structure: [{ "hospitalName": "hospital1", "category": "Injury & Poisoning", "Females": "0", "Males": "4"

问题 In difference to nearly 99.9% of all Gnuplot bar chart examples I don't have a data file but a function I want to visualize as a bar chart. Let us take for example take the simple function f(x) = x I want a bar char that creates one bar for every value of x between 0 and 20 (step size 1). Therefore I used the following code, but it does not create 20 bars - it creates a lot more (about 100?). set xtic 1 set xrange [0:20] set boxwidth 1 set style fill solid f(x)=x plot f(x) with boxes How to

I would like to have an Y Axis value increasing logarithmically, that show something like this (see the y Axis) : I tried to change yAxis scale, yAxis Domain, but didn't find any working solution (FYI: I use nvd3 through angularJs directives) 回答1: This will work for you chart

How to organize error bars to relevant bars in a stacked bar plot in ggplot?

问题 I stacked the bar plots from three different treatment together for comparison. However, I am having trouble putting the error bars in the right position. I am not sure if my codes are correct since I have a feeling that this should be an easy fix. Any help would be appreciated. dff <- structure(list(month = structure(c(1L, 1L, 1L, 2L, 2L, 2L, 3L, 3L, 3L, 4L, 4L, 4L), .Label = c("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"), class = c("ordered", "factor")
