Default Chart drawing speed/data retrieval

Is there some setting where I can tell NT to store the data that it retrieved for a chart on the hard drive or something rather than have it retrieve it every time I switch between time frames? Here is my problem:

I want to view a 1 minute chart, then a 3, 5, 15, and maybe then 30 or 60 minute chart of the same stock. Then I want to go back to a smaller time frame with as little delay as possible. I've noticed that when I format the data series to go back more than a few weeks, like say a year or so, this slows things down a lot. I understand why this might be so at first, but why does it keep on doing that?

What I mean is if I for example type INTC in a chart (60 minute, back 365 days), then yeah ok, so NT has to go get the data. So then I click on 30, 15, 5, 3, 1 minute charts. And, if I have already clicked on 30, 15, 5, 3, 1 minute charts and then want to say go back to 1 or 3 or 5 minute chart, most of the data should already be there shouldn't it? It should just need to retrieve just the last few minutes of data. If I just sit there and switch between 1 and 3 minute charts a few times for example, it always retrieves data. Why? It's mostly the same data. Heck today is Sunday so it's always the same data!

I mean it's actually faster to disconnect from the data feed and redraw the chart! Which works today since it's Sunday, but to connect and reconnect over and over again during a trading day would not be so convenient. Is there some setting where I can tell NT to store the data that it retreived for a chart on the hard drive or something rather than have it retrieve it every time I switch between time frames?

Hello,

I recommend selecting less historical data to get the chart to load up quicker.

This link may help explain why and when this happens:
