Hi,

```auto
fig = pygmt.Figure()

with fig.subplot(
    nrows=1,
    ncols=1,
    subsize=("15c", "10c"),
    frame=["WSne", "x+lPlace", "y+l# Fight"],     
    margins=["0.5c", "0.75c"],
):
    pen = "1.5p"

    with fig.set_panel(panel=0):
        fill = "blue"
        fig.basemap(region=[0, 4, 0, 15], frame="+t Tom vs Jerry")
        fig.plot(x=1+offset, y=10, style="b1c", fill=fill, pen=pen)
        fig.plot(x=1-offset, y=9, style="b1c", fill=colr,pen=pen)     
     
     
        fig.plot(x=3+offset, y=5, style="b1c", fill=fill, pen=pen, label="Tom")
        fig.plot(x=3-offset, y=12, style="b1c", fill=colr,pen=pen, label="Jerry")        
        fig.legend(position="JBL+jTR+o0.7c", box="+gwhite+pblack")     

fig.show()

```

How can I replaced the tick label to “Kithcen”, and “Backyard”.  
Also, how can I add grid lines.

Thank you!

you likely need this approach [4.3.8. Custom axes](https://docs.generic-mapping-tools.org/latest/reference/options.html#custom-axes)

@mkononets thank you for the link. Do you have any suggestions or link on converting GMT to pygmt codes.

Thank you

```auto

#The coord is the location of the desired annotation, tick, or grid-line,
#whereas type is a string composed of letters from
#a (annotation), i interval annotation, f frame tick, and g gridline.
#You must use either a or i within one file; no mixing is allowed.
#The coordinates should be arranged in increasing order. 
#If label is given it replaces the normal annotation based on the coord value.
