/* Flot plugin for adding the ability to pan and zoom the 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
|
|
"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.
|
