Solved the error in the Overall Chart

    In the Overall chart on the X axis we had the time in seconds
    instead of the money value.

    Added two lines of code to convert the time in money.

    The Overall chart draws the data related to money value.
    Added a label with money value to bars in the Overall chart.
    Added a explanatory note on the "30 days" chart about the bars tooltip.
    Other small changes.
