Hi,

I'm trying to display a graphic containing:
- The closing prices of a stock as a line => Timeseries graphic
- The different prices of the executions => scatter plots graphic as a timeseries dataset does not accept multiple values for one day.

How can this be done ?
How can I make the abscissa match as the datasets don't accept the same type of data ?

I've thought of using an High Low chart, but I have to much values for some days...
