4. Support for wxPython. | ||
___ | ||
|
||
### 1. Display data from a csv: | ||
|
||
```python | ||
import pandas as pd | ||
from lightweight_charts import Chart | ||
|
||
|
||
if __name__ == '__main__': | ||
|
||
chart = Chart() | ||
|
||
# Columns: | time | open | high | low | close | volume (if volume is enabled) | | ||
df = pd.read_csv('ohlcv.csv') | ||
chart.set(df) | ||
|
||
chart.show(block=True) | ||
|
||
``` | ||

___ | ||
|
||
### 2. Updating bars in real-time: | ||
|
||
```python | ||
import pandas as pd | ||
from time import sleep | ||
from lightweight_charts import Chart | ||
|
||
if __name__ == '__main__': | ||
|
||
chart = Chart() | ||
|
||
df1 = pd.read_csv('ohlcv.csv') | ||
df2 = pd.read_csv('next_ohlcv.csv') | ||
|
||
chart.set(df1) | ||
|
||
chart.show() | ||
|
||
last_close = df1.iloc[-1] | ||
|
||
for i, series in df2.iterrows(): | ||
chart.update(series) | ||
|
||
if series['close'] > 20 and last_close < 20: | ||
chart.marker(text='The price crossed $20!') | ||
|
||
last_close = series['close'] | ||
sleep(0.1) | ||
|
||
``` | ||
|
||

import pandas as pd | ||
from time import sleep | ||
from lightweight_charts import Chart | ||
|
||
|
||
if __name__ == '__main__': | ||
|
||
df1 = pd.read_csv('ohlc.csv') | ||
|
||
# Columns: | time | price | volume (if volume is enabled) | | ||
df2 = pd.read_csv('ticks.csv') | ||
|
||
chart = Chart(volume_enabled=False) | ||
|
||
chart.set(df1) | ||
|
||
chart.show() | ||
|
||
for i, tick in df2.iterrows(): | ||
chart.update_from_tick(tick) | ||

def avg(d: pd.DataFrame): | ||
return d['close'].mean() | ||
result = [] | ||
for i in range(period - 1, len(data)): | ||
val = avg(data.iloc[i - period + 1:i]) | ||
result.append({'time': data.iloc[i]['date'], 'value': val}) | ||
return pd.DataFrame(result) | ||
|
||
|
||
if __name__ == '__main__': | ||
|
||
chart = Chart() | ||
|
||
df = pd.read_csv('ohlcv.csv') | ||
chart.set(df) | ||
|
||
line = chart.create_line() | ||
sma_data = calculate_sma(df) | ||
line.set(sma_data) | ||
|
||
