Repeated measurement types above chart

[BNNorman]

It appears that the web page sometimes displays the reading type twice above the chart.
At first I thought it was only Pressure and looked at other sensors - then it happened with PM2.5.
See screen shots below.

Hrm, that's really strange. Perhaps it's not removing old ones from the graph correctly? Are you clicking any of the blue buttons at all @BNNorman?

[BNNorman]

You might like to think about that last question. Lol. How else would i get the chart up?

[sbrl]

Ah I mean the blue buttons below the graph. I know about the blue pins lol

[BNNorman]

The purple buttons? Yes.

Ah, I see. Sounds like it's not clearing the chart correctly then.

The duplication there is because using the chart library I'm using here you can display more than one line at a time on the graph (great for comparing multiple sensors, if I can work out the UI for it!).
