        public LineChart​(int lineSampleInterval,
                 long sampleInterval,
                 java.lang.String format,
                 java.lang.String detailFormat,
                 int averageWindow,
                 boolean antialias)
        Parameters:
        lineSampleInterval - The interval in data points at which to place vertical lines and labels along the x (time) axis.
        sampleInterval - The number of milliseconds represented by each data sample.
        format - Format of the text which is displayed along the x (time) axis of the chart. The text will display the time of the line chart at a particular interval. The text should take the format "{0}/{1}/{2} {3}:{4}:{5}.{6}" where {0} is replaced by the year, {1} by the month, {2} by the day, {3} by the hour, {4} by the minute, {5} by the second, and {6} by the hundereths of a second.
        detailFormat - Format of the text which is displayed over the component as the user moves the mouse over the line chart. The text will display the exact value of the line chart at a particular point. The text should take the format "{0}/{1}/{2} {3}:{4}:{5}.{6}" where {0} is replaced by the year, {1} by the month, {2} by the day, {3} by the hour, {4} by the minute, {5} by the second, and {6} by the hundereths of a second.
        averageWindow - Number of data points to do a moving average over when the mouse is pressed on the component.
        antialias - True if Antialiasing should be used when rendering the chart.
