How do I change the color or style of my lines?

The default colors for Usage and Generation can be changed from the Preferences menu, under Settings -> Preferences. This can be helpful for users with red/green colorblindness. Note that this is a global change - every register without a custom line style will be modified.
1. Select Settings from the top right corner of the screen.
2. Select Preferences from the menu on the left side of the screen.
3. Navigate down the page to "Color that represents energy usage (negative numbers)" and "Color that will represent energy generation (positive numbers)". Clicking the colored box containing color hex codes will bring up a color selection palette. The selected color(s) will replace the default red/green coloration on every register (including the shaded areas "Energy Used" and "Energy Generated") except those that have different colors/line styles specified on the Preferences page. 
4. Make sure to click "Save" at the bottom of the page.

You may use custom register styles to change the color and line style of a specific register. This can be done under Settings -> Preferences, in the "Custom Register Styles" field. Each custom register style has the following options: 

Register    Which physical register should appear in the defined style
Color Color for the chosen register (clicking here opens a color palette)
Line Line style and thickness
Sign Whether to style the line for positive, negative, or both signs

Below is an example where a subgroup of registers is configured to use unique colors and solid (rather than dotted) lines:


Note that you must click "Save" at the bottom of the page to save any changes. The main graph page will also need to be reloaded to show the changes. Changes here cannot cause a loss of historical data or other problems, so feel free to experiment!
