Timebars

We provide timebars, which the user can drag to filter in/out nodes. Please checkout the Getting started section to see how to hook ogma filter to the timeline.

Let's see how to bring some colors into this.

Add Timebars

Timebars are defined by the timeBars option. You can pass a number, a Date or an Object.

const controller = new Controller(ogma, document.getElementById("timeline"), {
  timeBars: [
    0,
    new Date("1/7/1950"),
    { fixed: true, date: new Date("1/7/1960") },
  ],
});

The effect of timebars is defined by the filter option. Please check the filtering section for further details on the filtering option.

const controller = new Controller(ogma, document.getElementById("timeline"), {
  nodeFilter: {
    enabled: true,
    strategy: "between",
    tolerance: "strict",
  },
});

You can access the timebars via controller.getTimebars You can add and remove timebars via: controller.addTimebar and controller.removeTimebar and .setTimebars.

Fixed Timebars

By default timebars move around while dragging the timeline. If you which for having fixed timebars, just pass:

const controller = new Controller(ogma, document.getElementById("timeline"), {
  timeBars: [
    { fixed: true, date: new Date("1/7/1950") },
    { fixed: true, date: new Date("1/7/1960") },
  ],
});
