For fun project with stock tickers.

I have a TimeSeriesChart in perspective I am trying to show prices in. I made a named query that grabs the date and closePrice of the day and a function that provides this data along with a name to the series property but then it comes through as just showing `closePrice` which makes it impossible to differentiate

with the series like

The only way I was able to get the actual ticker name on the chart as to make the column name the ticker name when I create the data like

```python
series = [
    {
        'name':ticker,
        'data':system.dataset.toDataSet(['date',ticker], 
        system.db.runNamedQuery('tickers/getPriceFromYear',{'ticker':ticker,'year':year}))
    }
    for ticker in tickers]

```

However this then makings union-ing the datasets in the series not work immediately due to all of them having different column names.

I was able to randomly assign colors by changing `plots[0].trends` so I thought that might be where I was able to modify the labels and keep the datasets the same column setup, but I had no luck.

It feels like I am missing something here about how to label the lines - that I should be able to have each series data property have the same dataset structure with a `date,closePrice` columns and then only modify how it's shown on the UI in some property - but I can't figure it out. Is this possible, or do I need each dataset to have the ticker name as the column name?
