If it is an EOD data, it will just have the OHLC for the day. Therefore, you cannot change to look the 5 min, 15 min, etc.
If you feed in IEOD 1 min intraday data, it will have OHLC for every one min, by right clicking on the chart/Intraday, you can choose the required time frame like 5 min, 15 min.
Problem could be not feeding in the right type of data. Charts are upward compatible. If you have 1 min data, you can get charts for time frame from 1 min and above. If you have 5 min data, you cannot get 1 min data, you can get charts for time frame from 5 min and above.
