Bar chart append mode series ordered randomly

### Current Behavior

I'm using the simplest mode bar chart with no special setup. Just a bar chart with `append` mode using `topic` to identify series. Works great but seems that series are ordered by the order in which they arrive which makes the graph non-deterministic when showing multiple bars.

### Expected Behavior

I'd expect the bars (series) in `append` mode to be ordered by `msg.topic`.

### Steps To Reproduce

Create a bar chart, set to append mode by topic. Inject `topic2` then `topic1`, the series will be displayed as received. Restart everything, inject in different order, bar chart changes order of the bars.
