I am trying to make a chart where every first of each month the chart updates its self if anyone who has a solution or an idea i would be so grateful.
def create_bar(self): # The QBarSet class represents a set of bars in the bar chart. # It groups several bars into a bar set set0 = QtCharts.QBarSet("markup") set1 = QtCharts.QBarSet("liabil") # set data # initial data = current sales and expenses if datetime.now().day == datetime.now().month: set0 << self.total_sales() set1 << self.total_expenses() else: set0 << self.total_sales() set1 << self.total_expenses() # load data to chart series = QtCharts.QBarSeries() series.append(set0) series.append(set1) # initialize chart chart = QtCharts.QChart() chart.addSeries(series) chart.setAnimationOptions(QtCharts.QChart.SeriesAnimations) categories = datetime.now().strftime('%b') axis = QtCharts.QCategoryAxis() axisY = QtCharts.QValueAxis() axis.append(str(categories), 0) chart.addAxis(axisY, QtCore.Qt.AlignLeft) series.attachAxis(axisY) axisY.setRange(0, 10000) chart.setAxisX(axis, series) chart.legend().setVisible(True) chart.legend().setAlignment(Qt.AlignBottom) self.place = QtWidgets.QVBoxLayout(self) self.place = QtWidgets.QVBoxLayout(self.ui.widget_2) self.place.setContentsMargins(0, 0, 0, 0) self.chartview = QtCharts.QChartView(chart) self.chartview.setRenderHint(QPainter.Antialiasing) self.chartview.setContentsMargins(0, 0, 0, 0) self.place.addWidget(self.chartview)

Where is your question?
if the current month is over the chart updates
Cant you just replace this statement with
"every first of each month"? When it is the first of any month, the last month is most likely over ;-)
Since you updated your question... I meant this literally. You could check
if datetime.now().day == 1.
What kind of program is this? Should it keep on running all the time or do you want to update, when you start your program?

Update itself when/in response to what? You have to clarify what you are looking to do.
