flot-parkinglot-plugin Build Status

This is a plugin for flot to enable the parking lot. With the parking lot a cursor/axis handel can be dragged fully off the edge of the graph. Once the handle is off the edge of the graph, it will show up in the respective graph parking lot corner.


Parking lot the area for off graph handles at the four corners of the graph.

Docker the container of the handles in the parking lot (at the red arrowhead).

Docker arrow indicates the orientation of the docker (at the yellow arrowhead).


The parking lot should be used with flot-cursors-plugin or flot-axishandle-plugin. The parking lot requires flot-cursors-plugin 4.x and flot-axishandle-plugin 2.x.

npm install flot-thumb-plugin flot-cursors-plugin flot-axishandle-plugin flot-parkinglot-plugin

Run the plot function and specify the parking lot in the options.

var myFlot = $.plot( $("#graph"), ...,
    cursors: [
            mode: 'x',
            position: {
                relativeX: 0.75,
                relativeY: 0.5
            showThumbs: 't'
    axisHandles: [
        { orientation: 'vertical', location: 'far' }
    parkingLot: {}


The plugin supports these options:

    parkingLot: {
        offset: 35,
        show: true

offset the distance between the graph area and the parking lot. Default value is 35.

show if the parking lot is shown or hidden. Default value is true.

CSS classes

The dockers and docker arrows are the SVG elements. I predefined some CSS classes to allow the users to customize how dockers and arrows display.

parkingLot-docker describes how the docker rectangles display.

parkingLot-dockerArrow describes how the docker arrows display.

    .parkingLot-dockerArrow {
        fill: gray;
        stroke: white;
    .parkingLot-docker {
        fill: none;
        stroke: black;
        stroke-width: 0.5;
