Hello,

I’m using Gantt enterprise 9.0.4 and export module 9.0.4.
I’ve tried to set smart_scales and smart_rendering to false but bug remains.
Scales are shown incorrectly only on export results.

Best regards,
David

Hello,
This is a known issue that will be addressed in the future. In the meantime, you can try disabling the sticky property for each scale before exporting the data, and then revert the changes afterward:

function exportData() {
    gantt.config.scales.forEach((scale) => {
        scale.sticky = false;
    })

    gantt.exportToPDF({
        raw: true
    });

    gantt.config.scales.forEach((scale) => {
        delete scale.sticky;
    })

    gantt.resetLayout();
}

Hello Dawid,
The dev team fixed the issue with the sticky scale cells in the exported PDF files.
You can see that the issue is no longer reproduced in the following snippet:
