/* | ||
Flot plugin for adding panning and zooming capabilities to a plot. | ||
The default behaviour is double click and scrollwheel up/down to zoom | ||
in, drag to pan. The plugin defines plot.zoom({ center }), | ||
plot.zoomOut() and plot.pan(offset) so you easily can add custom | ||
controls. It also fires a "plotpan" and "plotzoom" event when | ||
something happens, useful for synchronizing plots. | ||
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. | ||
