Could you really help with the following:

ie i need to have 4 buttons: "Hourly", "Daily","Weekly","Monthly"

So that when "Hourly" is clicked i need the chart to display the hourly data for the month.
Likewise when "Daily" is clicked i need the chart to display the Daily data for the month.
Likewise when "Weekly" is clicked i need the chart to display the Weekly data for the month(ie the chart should show the sum of values in a week, so that it will show 4 weekly points of the month).
Likewise when "Monthly" is clicked i need the chart to display the Monthly data for the month(ie the chart will have only one point that will be the sum of all values of the month).
