How to compare two graphs of companies data

Question

I can plot a graph for one company at a time. For example :

    DateListPlot[Entity["Company", "NVIDIACorporation::7ymsk"][EntityProperty["Company","GrossProfit", {"TimeSeriesType" -> #, "Date" -> All}]], ImageSize -> 200, PlotLabel -> #, PlotTheme -> "Business"] & /@ {"Annual", "Quarterly", "TTM"}

How could I compare two "TTM" values of this company and another company on a graph. I tried various things, but I still can't figure it out.

EDIT: I tried to somehow move the pure function, so that it could compare two companies. It turns out I only got to compare two properties of the same company. CODE:

DateListPlot[[EntityProperty["Company","GrossProfit",{"TimeSeriesType"->#,"Date"->All}]]&/@{"TTM", "Annual"},ImageSize->200,PlotLabel-> "Graph",PlotTheme->"Business"]

If you include a list of time series as first argument of DateListPlot you will get a plot with multiple curves.

Here is an example where I plot "TTM" and "Quarterly" of the given company in the same plot. For clarity, I first create the time series separately and subsequently feed them to DateListPlot:

ds1 = Entity["Company", "NVIDIACorporation::7ymsk"][
   EntityProperty["Company", 
    "GrossProfit", {"TimeSeriesType" -> "TTM", "Date" -> All}]];
ds2 = Entity["Company", "NVIDIACorporation::7ymsk"][
   EntityProperty["Company", 
    "GrossProfit", {"TimeSeriesType" -> "Quarterly", "Date" -> All}]];
DateListPlot[{ds1, ds2}]

If we want to restrict the dates to plot, we can do so e.g. by:

DateListPlot[{ds1, ds2},PlotRange -> {{{2005, 1, 1}, {2020, 1, 1}}, Automatic}]
