Scatter plot is skiping some data

Dash Python
1

Hi all,
I just started working with Dash and I developed a simple app for plotting some data from JSON file (almost 6000 data points). Unfortunately, it seems that I cannot plot last 100 entries in the dataset somehow. Has anyone encountered that kind of problem?

import dash
import dash_core_components as dcc
import dash_html_components as html
import pandas
import json
import time
from time import mktime
from datetime import datetime

import plotly
import plotly.graph_objs as go

def readJson_file():
    with open(r"C:\Users\KWierzbowski\Documents\CPU_MONITOR_SCRIPTS\test_cpu\database_split_crontab_date_test.bk.json", 'r') as f:
        readJson = json.load(f)
    data = {'Monitor':{'service':{'cpu':{'usage': [], 'total': [], 'time':[]},'memory':{'usage': [], 'total': [], 'time':[]}}}}
    for i in readJson['Monitor']:
        if 'cpu' in i['service']:
            data['Monitor']['service']['cpu']['usage'].append(i['service']['cpu']['data']['cpu usage'])
            data['Monitor']['service']['cpu']['total'].append(i['service']['cpu']['data']['total cpu usage'])
            data['Monitor']['service']['cpu']['time'].append(datetime.fromtimestamp(mktime(time.localtime(float(i['service']['cpu']['date'])))))
        elif 'memory' in i['service']:
            #data['Monitor']['service']['memory']['usage'].append(i['service']['memory']['data']['cpu usage'])
            #data['Monitor']['service']['memory']['total'].append(i['service']['memory']['data']['total cpu usage'])
            data['Monitor']['service']['memory']['time'].append(datetime.fromtimestamp(mktime(time.localtime(float(i['service']['memory']['date'])))))
    return  data

app = dash.Dash()

df_json = pandas.DataFrame(readJson_file())


app.layout = html.Div([
    dcc.Graph(
        id='cpu usage vs date',
        figure={
            'data': [
                go.Scatter(
                    x=sorted(df_json['Monitor']['service']['cpu']['time']),
                    y=df_json['Monitor']['service']['cpu']['usage'],
                    text='Cpu',
                    )
			],
            'layout': go.Layout(
				title='CPU monitor',
                xaxis={'title': 'Date'},
                yaxis={'title': 'CPU usage'},
                legend={'x': 0, 'y': 1},
                hovermode='closest'
            )
        }
    )	
])

    app.run_server()`Preformatted text`
