What is the reason for matplotlib for printing labels multiple times?

I hope this helps . You're plotting them all on the same figure so the labels are repeating because you are putting 3 different plots with identical labels on the same figure (so you'd see each label three times). You can see this by calling plt.show() at the end which gives you just a single figure that looks like this (I scrunched it down to fit my computer screen).

import pandas as pa
from datetime import datetime
import matplotlib.pyplot as plt



data = [['2018-10-29', 53, 'Anna Smith'],['2018-10-30', 118, 'Anna Smith'],['2018-10-31', 142, 'Anna Smith'],['2018-10-31', 7, 'Dominic Smith'],['2018-10-30', 1, 'Unknown Name'],['2018-10-29', 33, 'Jade Smith'],['2018-10-30', 103, 'Jade Smith'],['2018-10-31', 105, 'Jade Smith'],['2018-10-29', 41, 'Joanna Smith'],['2018-10-30', 169, 'Joanna Smith'],['2018-10-31', 220, 'Joanna Smith'],['2018-10-29', 31, 'John Smith'],['2018-10-30', 61, 'John Smith'],['2018-10-31', 79, 'John Smith'],['2018-10-29', 44, 'Nataly Smith'],['2018-10-30', 100, 'Nataly Smith'],['2018-10-31', 120, 'Nataly Smith'],['2018-10-30', 25, 'Sebastian Smith'],['2018-10-31', 47, 'Sebastian Smith'],['2018-10-29', 52, 'Veronica Smith'],['2018-10-30', 74, 'Veronica Smith'],['2018-10-31', 77, 'Veronica Smith']]
resultRunningTotal = pa.DataFrame(data, columns = ['date', 'runningTotal','name']) 
resultRunningTotal['date'] = pa.to_datetime(resultRunningTotal['date']).dt.date
print(type(resultRunningTotal))
print(resultRunningTotal.dtypes)

plt.figure(figsize=(24,13.5))
TuniqueDates = resultRunningTotal['date'][~resultRunningTotal.duplicated(['date'])]
dfUniqueDates = pa.DataFrame(TuniqueDates)
dfUniqueDates.sort_values(by=['date'], inplace=True, ascending=True)
startDate = min(dfUniqueDates['date'])

def savePlot (tDF, fig):
   listOfUniqueNames = tDF['name'].unique() 
   #print(tDF) #print_no_2
   for n in listOfUniqueNames:
      tDF2 = tDF[tDF.name == n]
      plt.figure(fig)
      tDF2.plot(kind='line',x='date',y='runningTotal',ax=plt.gca(),linewidth=3,label = n)

for d in dfUniqueDates['date']:
    mask = (resultRunningTotal['date'] >= startDate) & (resultRunningTotal['date'] <= d)
    tempDF5 = resultRunningTotal.loc[mask]
    fig_num = dfUniqueDates['date'].tolist().index(d)
    savePlot(tempDF5, fig_num)
    plt.savefig(str(d)+'plot.png')
plt.show()

How do I assign multiple labels at once in matplotlib?

Hope that helps It is not possible to plot those two arrays agains each other directly (with at least version 1.1.1), therefore you must be looping over your y arrays. My advice would be to loop over the labels at the same time:

import matplotlib.pyplot as plt

x = [0, 1, 2, 3, 4]
y = [ [0, 1, 2, 3, 4], [5, 6, 7, 8, 9], [9, 8, 7, 6, 5] ]
labels = ['foo', 'bar', 'baz']

for y_arr, label in zip(y, labels):
    plt.plot(x, y_arr, label=label)

plt.legend()
plt.show()

How to create ASP.NET labels multiple times by clicking a button multiple times

help you fix your problem Solution 1: You are just replacing the new label with old one but not adding to existing labels that's why you are not able to see the multiple labels even when you clicked a button multiple times.
Replace this:

lbl_homeCarouselAdd.Text = strDiv.ToString();

lbl_homeCarouselAdd.Text += strDiv.ToString();

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Diagnostics;
using System.Text;

namespace addlabels
{
    public partial class WebForm1 : System.Web.UI.Page
    {

        int pressNumberOfTimes;
        Label lbl_homeCarouselAdd = new Label();
        static StringBuilder strDiv = new StringBuilder();
        protected void Page_Load(object sender, EventArgs e)
        {

        }


        protected void add_click(object sender, EventArgs e)
        {
            // Add the panel
            pressNumberOfTimes++;



            // Set the label's Text and ID properties.
            lbl_homeCarouselAdd.ID = "lbl_homeCarouselAdd" + pressNumberOfTimes;


            strDiv.Append(string.Format(@"<p class='style'>Hello world</p>"));

            lbl_homeCarouselAdd.Text += strDiv.ToString();


            Panel1.Controls.Add(lbl_homeCarouselAdd);
        }
    }
}

Multiple labels in Matplotlib

Any of those help 'the initial state' already is a string, so you do not need to cast it again.
I do not see a syntax error for the moment, but surely you cannot set the label twice.

the_initial_state = 'the initial state {}'.format(t[0])
plt.plot(x,Pd[0],'r',label= the_initial_state)

Matplotlib is printing the line plot twice/multiple times

it fixes the issue This is because plotting df[1:] is plotting the entire dataframe as the x-axis.
