Hi
I have created the following plot. But i cannot figure out how to set a text for the y-axis values. Meaning, instead of displaying value 0 in the y-axis, i want it to display the text Offline; for the value 1, i want to display Present etc.
This is my form code:
from ._anvil_designer import Form1Template
from anvil import *
import plotly.graph_objects as go
import anvil.tables as tables
import anvil.tables.query as q
from anvil.tables import app_tables
import anvil.server
import datetime
class Form1(Form1Template):
# Status mapping to numerical values for the y-axis
status_mapping = {
'Offline': 0,
'Present': 1,
'Busy': 2,
'Ringing': 3
}
def __init__(self, **properties):
# Set Form properties and Data Bindings.
self.init_components(**properties)
# Any code you write here will run before the form opens.
def button_1_click(self, **event_args):
app_tables.table_2.add_row(Column1=datetime.datetime.now())
def button_1_copy_click(self, **event_args):
# This button presumably fetches the data and updates the plot
start_time = "03:00"
end_time = "10:00"
rows_between_dates = anvil.server.call('get_rows_between_dates', start_time, end_time)
# Process the data into a plot-friendly format
plot_data = self.process_data_for_plot(rows_between_dates)
# Plot the data
self.plot_status_data(plot_data)
def process_data_for_plot(self, data):
# This function transforms the data into a format that can be plotted
plot_data = {}
for record in data:
timestamp = record['dt']
for item in record['data']:
if item['name'] not in plot_data:
plot_data[item['name']] = {'x': [], 'y': []}
plot_data[item['name']]['x'].append(timestamp)
# Use the mapping for statuses
status_value = self.status_mapping.get(item['status'], -1) # Default to -1 if status is not found
plot_data[item['name']]['y'].append(status_value)
return plot_data
def plot_status_data(self, plot_data):
# Clear any existing data
self.plot_1.data = []
for name, series in plot_data.items():
trace = go.Scatter(
x=series['x'],
y=series['y'],
mode='lines+markers',
name=name
)
self.plot_1.data = self.plot_1.data + [trace]
# Update the layout for the y-axis to display custom tick labels
self.plot_1.layout.yaxis = {
'tickvals': list(self.status_mapping.values()),
'ticktext': list(self.status_mapping.keys())
}
# Update other layout properties
self.plot_1.layout.title = 'Status Over Time'
self.plot_1.layout.xaxis.title = 'Time'
self.plot_1.layout.yaxis.title = 'Status'
The data which i am displaying looks like this:
Any help is appreciated
