To load a comma separated value (CSV) formatted file click the 'Choose CSV File' button. The first line of the file should list the names of each column of values. The data types of the column values will be automatically determined. Columns with valid date values will be available from the 'Settings' dialog to map to the x-axis of the charts. The last date value in the list of columns will be selected by default. The other numeric columns will be shown as separate charts. An example CSV file can be viewed here. This data can also be viewed from the 'Load Sample Data' menu option.
The 'Redraw' button can be used to regenerate all the visible charts. If the window is resized, regenerating the plots will adjust the chart widths.
The 'Settings' button can be used to control several visual parameters of the charts.
Each chart has a close icon located at the top right of the chart. Click the close icon to remove the chart.
