I was playing around with some of the chart ui’s and had some feedback.

For 05\_od.yaml  
I added/changed these lines:

```auto
fixed_decimals: 2
y_transformation: "(y) => 1000 * y"
y_axis_domain: [0,12]

```

The highest reading I have seen on this graph is ~0.012-0.013 V, so it’s easier to show it mV. When I didn’t include the y\_axis\_domain setting, the graph wasn’t visible on the chat (but when I hovered my mouse over it, the data points would still show up).

for 04\_normalized\_od.yaml  
I added/changed these lines:

```auto
fixed_decimals: 4

```

It’s nice to be able to see a couple more decimal points.

Just food for thought.
