Histogram Cell width does not take full width in custom view

I have my histogram set up. This is what it looks like in the default Day view.

As you can see the green and red background takes up the entire cell background.

However when I switch to a custom view, the green and red don’t span the entire cell.

Here is where I apply the styles

gantt.templates.histogram_cell_class = function (start_date, end_date, resource, tasks) {

    let totalEffort = ...

    let css = '';

    if (totalEffort > resource.capacity) { //1 = 8h or 100% allocation
       css = "column_overload";
    }
    else if (totalEffort > 0)
        css = "column_steady";

    return css;


}.bind(this);

Here are my styles

.gantt_histogram_fill {
    background-color: rgba(176, 176, 176, 0.2);
}

.column_steady .gantt_histogram_fill {
    background-color: rgba(160, 202, 92, 0.7);
}

.column_overload .gantt_histogram_fill {
    background-color: #ffa9a9;
}

How can I get the background to fill the entire cell when the scale changes widths?

Hello,
Unfortunately, I couldn’t reproduce the issue:

And as I don’t see your code, it is hard to suggest what might be wrong.

Please, reproduce the issue in the snippet, then click on the “Share” button and send me the link:

Or send me an HTML file with all the necessary Javascript and CSS files.

Thanks I’ll reproduce it asap.
