Why is it so hard to fins information for plotly graph objects!

[twelsh37]

Hey All ,

Excuse the frustration. I am trying to find what I need to set in update_layout of plotly graph objects to show the background grid.
I want it in light great dashed lines.

I have spent about an hour trying to find what I’m looking for but to no avail.

i have the following code

fig = go.Figure(
    data = [
        go.Candlestick(
            x = df.index,
            low = df['Low'],
            high = df['High'],
            close = df['Close'],
            open = df['Open'],
            increasing_line_color = 'green',
            decreasing_line_color = 'red'
        )
    ]
    
)

fig.update_layout(xaxis_rangeslider_visible = False, height = 800)
fig.update_layout(
    title = 'Microsoft Share Price 1st Jan 2023 - 1st Jan 2024',
    xaxis_title = 'Date',
    yaxis_title = 'Stock Price - USD ($)',
    plot_bgcolor="rgba(0, 0, 0, 0)",
)
fig.show()

Wwhich created a Shareprice chart quite happily. I have the background colour set to white but I would like to put some x and y grid lines.

I feel that we should be able to finds this stuff easily, either that or I’m really tired.

I also looked for an ‘Anatomy of a chart’ incise I was using the wrong terminology but I cant find one of them either.

@adamschroeder maybe an idea for a future article.

anyone point me at the right place or just suggest what is should stick in my code?

thanks

The easiest way to achieve your wishes is to change the theme rather than setting individual background colors.

fig.update_layout(
    title = 'Microsoft Share Price 1st Jan 2023 - 1st Jan 2024',
    xaxis_title = 'Date',
    yaxis_title = 'Stock Price - USD ($)',
    #plot_bgcolor="rgba(0, 0, 0, 0)",
    template='plotly_white'
)

@r-beginners

template='plotly_white'

Thanks. I never use templates hence I never thought of that

Please refer to the https://plotly.com/python/templates/ for a nice example template.

Hi @twelsh37 I’m a bit late to the party, but maybe interesting:

You can switch on/off the gridlines:

fig.update_yaxes(showgrid=True)
fig.update_yaxes(showgrid=False)

To change the style of the grid:

import plotly.graph_objects as go

fig = go.Figure(go.Scatter(x=[1,2], y=[1,2], mode='lines+markers'))
fig.update_xaxes(gridwidth=3, gridcolor='red')
fig.update_yaxes(griddash='dash', gridcolor='black', gridwidth=2)

fig.show()
