Of instance to Handler as a keyword to legend. On the legend() function for convenience). Which accepts a numpoints argument (numpoints is also a keyword Sake of simplicity, let's choose legend_handler.HandlerLine2D The simplest example of using custom handlers is to instantiate one of theĮxisting legend_handler.HandlerBase subclasses. With the value in the handler_map keyword.Ĭheck if the handle is in the newly created handler_map.Ĭheck if the type of handle is in the newly created handler_map.Ĭheck if any of the types in the handle's mro is in the newlyįor completeness, this logic is mostly implemented inĪll of this flexibility means that we have the necessary hooks to implementĬustom handlers for our own type of legend key. The choice of handler subclass is determined by the following rules: In order to create legend entries, handles are given as an argument to an legend ( handles =, loc = 'lower right' ) plt. add_artist ( first_legend ) # Create another legend for the second line. legend ( handles =, loc = 'upper right' ) # Add the legend manually to the Axes. plot (, label = "Line 2", linewidth = 4 ) # Create a legend for the first line. plot (, label = "Line 1", linestyle = '-' ) line2, = ax. To keep old legend instances, we must add themįig, ax = plt. To call legend() repeatedly to update the legend to the latest This has been done so that it is possible The legend() function multiple times, you will find that only one Whilst the instinctive approach to doing this might be to call Sometimes it is more clear to split legend entries across multiple plot (,, label = 'test' ) for loc in : fig. subplots ( figsize = ( 6, 4 ), layout = 'constrained', facecolor = '0.7' ) ax. legend ( loc = loc, title = loc ) fig, ax = plt. plot (,, label = 'TEST' ) # Place a legend to the right of this smaller subplot. The legend is drawn outside the Axes on the (sub)figure. Specifying "outside" at the beginning of the loc keyword argument, Sometimes it makes more sense to place a legend relative to the (sub)figure legend ( bbox_to_anchor = ( 1.05, 1 ), loc = 'upper left', borderaxespad = 0. plot (, label = "test2" ) # Place a legend to the right of this smaller subplot. 102 ), loc = 'lower left', ncols = 2, mode = "expand", borderaxespad = 0. plot (, label = "test2" ) # Place a legend above this subplot, expanding itself to # fully use the given bounding box. subplot_mosaic (, ], empty_sentinel = "BLANK" ) ax_dict. This isn't utterly important though, and I'm just trying to learn using python, and the actual work has been done in excel.Fig, ax_dict = plt. I have come across a few other posts related to this issue, but not seen one that specifically addresses the renaming of individual labels. This is the error I get when using the above code.ĪttributeError: 'Series' object has no attribute 'set_ylabel' For x-axis : () For y-axis : () To create a list of ticks, we will use numpy.arange (start, stop, step) with start as the starting value for the ticks, stop as the non-inclusive ending value and step as the integer space between ticks. I have tried to rename the x-axis labels using the code below. Pd.set_option('display.mpl_style', 'default')įixed_data = pd.read_csv('audit-rep.csv',sep=',',encoding='latin1',index_col='Index', parse_dates=,dayfirst=False) This is the code I have used, and except for the label names, I am happy with the result. Instead of having these verbose reasons though, I would like to rename the X-Axis labels to just numbers or alphabets so that the graph reads somewhat like this: Vendor Registration not on record.another 300 words - 9.No contract with vendor.another 300 words - 14.Not approved by regional committee.another 300 words - 17.The problem I am facing is renaming the X-Axis labels.Įssentially, the chart is trying to plot a count of different types of Audit Violations, but has really long descriptions of the said violations. I have a CSV file that I am trying to read using Python, and looking to come up with charts. I'm running my code on iPython Notebooks, on a Macbook Pro Yosemite 10.10.4
