The plugin defines plot.zoom({ center }), plot.zoomOut() and +plot.pan( offset ) so you easily can add custom controls. It also fires +"plotpan" and "plotzoom" events, useful for synchronizing plots. + +The plugin supports these options: + + zoom: { + interactive: false + trigger: "dblclick" // or "click" for single click + amount: 1.5 // 2 = 200% (zoom in), 0.5 = 50% (zoom out) + } + + pan: { + interactive: false + cursor: "move" // CSS mouse cursor value used when dragging, e.g. "pointer" + frameRate: 20 + } + + xaxis, yaxis, x2axis, y2axis: { + zoomRange: null // or [ number, number ] (min range, max range) or false + panRange: null // or [ number, number ] (min, max) or false + } + +"interactive" enables the built-in drag/click behaviour. If you enable +interactive for pan, then you'll have a basic plot that supports moving +around; the same for zoom. + +"amount" specifies the default amount to zoom in (so 1.5 = 150%) relative to +the current viewport. + +"cursor" is a standard CSS mouse cursor string used for visual feedback to the +user when dragging. + +"frameRate" specifies the maximum number of times per second the plot will +update itself while the user is panning around on it (set to null to disable +intermediate pans, the plot will then not update until the mouse button is +released). + +"zoomRange" is the interval in which zooming can happen, e.g. with zoomRange: +[1, 100] the zoom will never scale the axis so that the difference between min +and max is smaller than 1 or larger than 100. You can set either end to null +to ignore, e.g. [1, null]. If you set zoomRange to false, zooming on that axis +will be disabled. + +"panRange" confines the panning to stay within a range, e.g. with panRange: +[-10, 20] panning stops at -10 in one end and at 20 in the other. Either can +be null, e.g. [-10, null]. If you set panRange to false, panning on that axis +will be disabled. + +Example API usage: + + plot = $.plot(...); + + // zoom default amount in on the pixel ( 10, 20 ) + plot.zoom({ center: { left: 10, top: 20 } }); + + // zoom out again + plot.zoomOut({ center: { left: 10, top: 20 } }); + + // zoom 200% in on the pixel (10, 20) + plot.zoom({ amount: 2, center: { left: 10, top: 20 } }); + + // pan 100 pixels to the left and 20 down + plot.pan({ left: -100, top: 20 }) + +Here, "center" specifies where the center of the zooming should happen. Note +that this is defined in pixel space, not the space of the data points (you can +use the p2c helpers on the axes in Flot to help you convert between these). + +"amount" is the amount to zoom the viewport relative to the current range, so +1 is 100% (i.e. no change), 1.5 is 150% (zoom in), 0.7 is 70% (zoom out). You +can set the default in the options. + +*/// First two dependencies, jquery.event.drag.js and +// jquery.mousewheel.js, we put them inline here to save people the +// effort of downloading them.
