Zoom and Pan :

• The easier way to zoom in your data is to make QPlot window bigger, either by pressing maximize button on the right top corner or by resizing the window dragging right bottom corner.
• If you are comfortable of the window size, but still want to get closer to some region, then you can use mouse click and drag to form a box surrounding the region you are interested. The region will be expanded to fill the full window.
• There is another shortcut to zoom in and out by using mouse wheel, each roll will give you 10% degree of zoom.

Reading and tracking:

• By default, chart coordinates is tracked automatically following your mouse cursor. No eye estimation is required.
• Press 'Spacebar' to lock or unlock this reading in case you want to record it
• Tips: for reading convenience, you can also lock the mouse go either horizentally or vertically by toggling "h" or "v" respectively.
• Whenever the chart gets updated, the published x/y ratio of the chart is tracked and updated at the right bottom of the chart.
• Tips: published x/y ratio is a value indicates if your chart is geometrically stretched. Ex. if x/y=2, the chart is stretched in x direction twice as much as y
• Press 's' to set x/y ratio to be 1:1 so that the chart is geometrically preserved that sometimes help you to get correct impression of the chart.

Maneuver multiple series :

• If "Multiple plot" options is set, you can add as many lines to the chart as you like.
• Legend panel lists all the series you have, if it's not visible, press 'l'
• There are two ways to select a series as active one, either by just clicking the series points, or by clicking the series title on the legend panel.
• Under menu "Series", select "Customize" to make line series look different, ex line, point, size, symbol.
