Describe the issue you are experiencing

After a recent PR (https://github.com/home-assistant/frontend/pull/19089) no "sum / change / state" labels are displayed in a legend:

chart_type: line
period: 5minute
type: statistics-graph
entities:
  - sensor.system_monitor_network_in
stat_types:
  - state
  - sum
  - change
days_to_show: 1

For total_increasing sensors it could be unclear which graph is for a "sum" etc, users have to guess.

In that mentioned PR it was proposed first to use 3 ways of showing a legend: -- full (incl. labels) -- brief (only entity names) -- none but the "full" option was refused.

Suggest to add this variant.

Even if you had the full legend, you just have three bubbles but they were all the same color, so that doesn't actually help you identify which one is which?

The tooltips still show the (sum) string btw.

Agree that same colors make it difficult, that is why I have to switch curves one by one to identity which one is for )). Tooltips are also informative, but I can use them only with a mouse, not on a touchscreen (personal issues). We should probably think how to differ lines visually. For min/mean/max it was a brilliant idea to use a background fill between lines. In case of state/sum/change also smth is required.

Also, about tooltips. Sometimes a popup shows data for several curves - you have to select another point to find out:

i.e. even tooltips may be confusing.

Also, in a perfect world a total_increasing sensor is always increasing - and you may understand a graph easier. In a real world integrations may make a sensor become a zero or start decreasing (could indicate an error) - so a graph may become "strange". That is why we need a way to define which curve is for.

Bumping up the issue. It is absolutely not convenient to use the statistics-graph in case of total & "total_increasing" sensors. All lines looks same, not easy to distinguish them.
