Hi, I try to configure the tick value on yaxis to be 0 , 4096, 8192 … by calling

fig.update\_yaxes(dvalue = 4096 … )

But the graph has ticks at 4100 8200 … . Any idea how to change it ?

Thanks and best regards  
XInwei

Hi @Xinwei,

print(help(go.layout.YAXis.dvalue) )

gives:

```auto
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-19-7ff3097698bd> in <module>
      1 import plotly.graph_objects as go
----> 2 help(go.layout.YAxis.dvalue)

AttributeError: type object 'YAxis' has no attribute 'dvalue'

```

To customize yaxis ticks, perform the following `yaxes_update`:

```auto
tickvals = [k*4096 for in range(0, n)] #give an appropriate n

fig.update_yaxes(tickvals=tickvals, ticktext=tickvals)

```
