histogram, config for grouping on startup

[pincherhgz]

we cannot find a configuration that switches the resources to the collapsed view instead of the expanded view on startup

[mats]

You mean you would like all groups to start collapsed?

[pincherhgz]

yes

Hi,

There is no such property now, I've opened a feature request for your request https://github.com/bryntum/support/issues/6642
You can try to use https://bryntum.com/products/gantt/docs/api/Grid/feature/Group#function-collapseAll when project's data is ready https://bryntum.com/products/gantt/docs/api/Gantt/model/ProjectModel#event-dataReady

we did now the collapsing after waiting for the project data to be ready by

project.commitAsync();

but this results in no histogram data painted. We have to wait until all the histogram is rendered before doing the collapse. This is really a strange behaviour

Could you give more details on how we can reproduce this? Like steps allowing to see this on some of our demos or a test case.

Just configure our SchedulerPro/resorcehistogram example like this:

const project = window.project = new ProjectModel({
    transport : {
        load : {
            url : 'data/data.json'
        }
    },
    autoLoad : true,

    // This config enables response validation and dumping of found errors to the browser console.
    // It's meant to be used as a development stage helper only so please set it to false for production systems.
    validateResponse : true,

    resourceStore : {
        startGroupsCollapsed : true
    }
});

const scheduler = new SchedulerPro({
    appendTo  : 'container',
    minHeight : '10em',
    flex      : '1 1 50%',

    startDate         : new Date(2020, 3, 26),
    endDate           : new Date(2020, 4, 10),
    viewPreset        : 'dayAndWeek',
    eventStyle        : 'plain',
    tickSize          : 70,
    resourceImagePath : '../_shared/images/users/',

    columns : [
        { type : 'resourceInfo', text : 'Name', field : 'name', width : 130 },
        { text : 'City', field : 'city', width : 90 }
    ],

    project,

    features : {
        group : {
            field : 'city'
        }
    }
});

It makes sense that both widgets start collapsed. The Resource Store actually only contains the group header records. Collapsing actually removes the group child records from the store, so the histogram has no access to the data.

So expand and collapse signals have to be shared between partnered Schedulers. They share one store, so must show the same data in the same expanded/collapsed state.

But attempting to expand one of the collapsed groups throw an error.

this hint works fine for us now:

resourceStore : {
        startGroupsCollapsed : true
    }
