Hi 🙂

I want to set the dpi for my TFR plot.

```python
grandAvg_forg.plot(['O1', 'Oz', 'O2'],title='TFR - forgotten',
                          baseline=[-0.40,-0.20], mode='logratio', combine='mean',
                        tmin=-1, tmax=3, show=True, cmap='viridis')

```

It works for other data when I use plt instead of plot, but with this code I dont know how to set the dpi

Best,  
Franzi

You can assign the figure that’s returned to a variable like `fig` and then do `fig.savefig(fname, dpi=300)` for instance.

`grandAvg_forg.plot(...)` like most MNE plotting function returns the figure. As @alexrockhill said, you can assign it to a variable. `fig = grandAvg_forg.plot(...)` and then work on this `fig` variable to further customize the plot to your liking.
