Hi Lucas,
Unfortunately, it is not possible to have an equal interval on both axes with equal spacing in a chart when the chart has different width and height. Even when the chart has the same width and height, the interval spacing is dependent on the visible range and data points, making it impossible to achieve a constant spacing between the interval on both axes.
If you have any further questions, please don't hesitate to reach out to us.
Regards,
Yuvaraj.
