can't get xticks to work

[iFunKtion]

Hi,

having a little difficulty getting xticks to work, but I can't find syntax for what I am doing. As it happens, I think the syntax is accepted by the interpreter, it's just that I haven't seem to put the parameters in correctly. As my data has strings as the xaxis, I have created a range of integers as Matplotlib does not seem to support the use of strings for this. The two print statements are just to make sure that I have two lists one of integers and the other of the names taken from the data:

#!/usr/bin/python3 # aniMat.py # Testing out updating live charts with MatPlotLib library. import matplotlib.pyplot as plt import matplotlib.animation as animation from matplotlib import style style.use('ggplot') fig = plt.figure() ax1 = plt.subplot2grid((8,1), (0,0), rowspan=3, colspan=1) ax2 = plt.subplot2grid((8,1), (4,0), rowspan=1, colspan=1) bar_width = 0.6 def animate(i):     pullData = open('./data_sets/sample.txt', 'r').read()     dataArray = pullData.split('\n')     xar = []     xar_labels = []     yar = []     xhar = [0, 1]     yhar = [40, 0]     t_used  = 0     n = 0     rflag = False     aflag = False          rag_array = []     for eachLine in dataArray:         if len(eachLine)>1:             x, y = eachLine.split(',')             xar_labels.append(str(x))             xar.append(int(n))             print(xar)             print(xar_labels)             yar.append(int(y))             t_used = t_used + int(y)             n = n + 1             if int(y) < 4:                 rag = 'green'             elif int(y) == 4:                 rag = 'orange'                 aflag = True             else:                 rag = 'red'                 rflag = True             rag_array.append(rag)     ax1.clear()     ax2.clear()          ax1.bar(xar, yar, bar_width, align='center', color=rag_array)     ax1.set_xticks(xar, xar_labels)          ax1.set_title('P1GTR Tyres')     ax1.set_ylim(0, 6)     ax1.set_ylabel('Tyres Used')     ax1.set_xlabel('VIN Number')     yhar = [40, t_used]     if rflag:         rag_sets = 'red'     elif aflag:         rag_sets = 'orange'     else:         rag_sets = 'green'              ax2.barh(xhar, yhar, color=['grey', rag_sets])     ax2.set_xlabel('Number of Sets')     ax2.set_xlim(0, 50)     ax2.set_ylim(0, 2)   ani = animation.FuncAnimation(fig,animate, interval=1000) plt.show()

I was hoping to be able to attach the text file I am drawing the data from, but couldn't work out how to do that on here, essentially, these are anywhere from 8 - 40 customers, so the x axis range is only ever going to be between 8 and 40 lines. The data I have taken is 8 lines of text in the following format of a name, a comma and a number from 1 to 5:
    James,2
    Paul,1
    etc.
If there is a simpler way to do this that would really help, as I am not confident that my code is going to get very slow over time. Eventually, all the data will be taken straight from a NoSQL database if I can work out how to do it.

Hi,

I have solved this, I had the set_xticks, but not the set_xticks labels, that part of the code now looks like this and works;

ax1.clear() ax1.bar(xar, yar, bar_width, align='center', color=rag_array) ax1.set_xticks(xar) ax1.set_xticklabels(xar_labels) ...

Kind regards
Rob
