Removing white space on graph components

Hi all,

I haven’t been able to figure out why my graph has a huge white space on the left of the axis. When I go through with inspect element, it seems like all the margins are set to zero. Is there a way to make the graph fill out the entire container? I have included the layout of my graph and a screenshot.

{
        'layout': go.Layout(
            title='Overall System',
            legend_orientation='h',
            legend=dict(x=0.2, y=-0.1),
            xaxis=dict(domain=[0.2, 0.90], title='Orbit Time (minutes)'),
            yaxis=dict(
                title='V', titlefont=dict(
                    color='rgb(255, 0, 0)'

                ),
                tickfont=dict(
                    color='rgb(255, 0, 0)'
                )
            ),
            yaxis2=dict(
                title='%',
                titlefont=dict(
                    color='rgb(0, 255, 100)'
                ),
                tickfont=dict(
                    color='rgb(0, 255, 100)'
                ),
                overlaying='y',
                side='right'

            ),
            yaxis3=dict(title="Current (A)",
                        titlefont=dict(
                            color="rgb(0,0,255)"
                        ),
                        tickfont=dict(
                            color="rgb(0,0,255)"
                        ),
                        anchor="free",
                        overlaying="y",
                        side="left",
                        position=0.14),
            yaxis4=dict(title="Power (W)", titlefont=dict(
                color="rgb(255,0,255)"
            ),
                        tickfont=dict(
                            color="rgb(255,0,255)"
                        ),
                        anchor="free",
                        overlaying="y",
                        side="right",
                        position=0.95)
        )
    }
