Another example is when braille is rendered as a block of dots, with the non-coloured dots also appearing. This may look strange for some users, and it is also caused by misconfiguration or missing fonts.

In either case, you may need to install a specific font and configure your terminal to use it. For example, installing [UBraille](https://yudit.org/download/fonts/UBraille/)
and ensuring your terminal uses should work.
Another alternative is to use the `--dot_marker` option to instead render graph charts using dots, which I've generally found to be better supported out of the box:
There are measures taken to try to maximize the amount of information obtained without elevated privileges, but there may still be some limitations.
## My configuration file isn't working
If your configuration files aren't working, here are a few things to try:
### Check the formatting
It may be handy to refer to the automatically generated config files or the [sample configuration files](https://github.com/ClementTsang/bottom/tree/master/sample_configs).
The config files also follow the [TOML](https://toml.io/en/) format.
Also make sure your config options are under the right table - for example, to set your temperature type, you must set it under the `[flags]` table:
```toml
[flags]
temperature_type = "f"
```
Meanwhile, if you want to set a custom color scheme, it would be under the `[colors]` table:
```toml
[colors]
table_header_color="LightBlue"
```
### Check the configuration file location
Make sure bottom is reading the right configuration file. By default, bottom looks for config files at these locations:
