When config_display option is set to columns, it uses CSS @media queries to adjust width dynamically.
However, since height needs to be fixed by the viewbox and height of the SVG, dynamic height resizing is hard (impossible?) to achieve (see #374).
Current workaround is to manually split the image by using multiples jobs, and use <img align="{left|right|center}"> to embed metrics.
If you know how to fix it, feel free to open an issue or comment
