Matplotlib表格式 [英] Matplotlib table formatting

问题描述

由于文本本身非常局促，因此似乎无法在文档中找到如何增加单元格的行高.

Can't seem to locate in the documentation how to increase the line-height of the cells, as the text itself is very cramped.

感谢您提供任何有关代码的帮助！表格式似乎没有很好的记录...

Any help with code is appreciated! Table formatting doesn't seem to be well documented...

    # Plot line width
    matplotlib.rc('lines', linewidth=3)

    ind = np.arange(len(overall))

    fig = pyplot.figure()
    ax = fig.add_subplot(211)
    ax.set_title('Overall Rating of Experience')
    ax.set_ylabel('Score (0-100)')

    # Plot data on chart
    plot1 = ax.plot(ind, overall)
    plot2 = ax.plot(ind, svc_avg)
    plot3 = ax.plot(ind, benchmark)

    ax.yaxis.grid(True, which='major', ls='-', color='#9F9F9F')
    ax.set_ylim([min(overall + svc_avg + benchmark) - 3, 100])
    ax.set_xlim([-.5,1.5])
    ax.get_xaxis().set_ticks([])
    ax.set_position([.25, .3, 0.7, 0.5])

    colLabels = ['July', 'August']
    rowLabels = ['Average', 'Service Average', 'Benchmark']
    cellText = [overall, svc_avg, benchmark]
    the_table = ax.table(cellText=cellText, rowLoc='right',
                         rowColours=colors, rowLabels=rowLabels,
                         colWidths=[.5,.5], colLabels=colLabels,
                         colLoc='center', loc='bottom')

感谢Oz的回答-遍历表的属性可以轻松修改height属性:

Thanks to Oz for the answer-- Looping through the properties of the table allows easy modification of the height property:

    table_props = the_table.properties()
    table_cells = table_props['child_artists']
    for cell in table_cells: cell.set_height(0.1)

推荐答案

matplotlib文档说

The matplotlib documentation says

向当前轴添加表格.返回matplotlib.table.Table实例.为了对表进行更精细的控制，请使用Table类，然后使用add_table()将其添加到轴中.

Add a table to the current axes. Returns a matplotlib.table.Table instance. For finer grained control over tables, use the Table class and add it to the axes with add_table().

您可以执行以下操作，查看表的属性(该属性和属于该类Table的对象):

You could do is the following, look at the properties of your table (it's and object belonging to that class Table):

print  the_table.properties() # hint it's a dictionary do: type(the_table.properties() <type 'dict'> 

按照您认为正确的方式编辑该词典，并使用以下方法更新表格:

edit that dictionary the way you see right, and the update your table, with:

the_table.update(giveHereYourDictionary)

提示:如果您使用IPython或交互式shell，则足以完成help(objectName)，例如help(the_table)查看所有对象的方法. 希望应该可以.

Hint: if you work with IPython or interactive shell it's enough to do help(objectName), e.g. help(the_table) to see all the object's methods. This should, hopefully, work.

好的，我在这里向您介绍如何处理此类内容.我承认，这并不简单，但是我使用matplotlib已有3.5年了，所以...

OK, I'm adding here a walk through of how to to that kind of stuff. I admit, it's not trivial, but I am using matplotlib for 3.5 years now, so ...

在IPython中执行您的代码(我之前说过，但是我必须再次强调)，它确实有助于检查对象具有的所有属性(键入对象名称，然后键入键):

Do your code in IPython (I said it before, but I must emphasize again), it really helps to examine all the properties that objects have (type object name and then the key):

和TA DA:

现在，我挑战您使用for循环来更改所有单元格的高度. 不应该那么难. 赢取赏金会很高兴;-)

Now, I challege you to change the height of all the cells, using a for loop. Should not be so hard. Would be nice to win that bounty ;-)
