forecasting

Once I add a forecast to a line chart, if I enable data labels, it shows the data points only for actual data and doesnt show for forecast data. Quite often the user has to hover over the line to see what value is being forecasted. We also need an option to customize the data labels, when we are showing 2-3 years of data monthwise or quarterwise, we dont need every label, it can be every alternate month or quarter or day and so on.
