labels stay static when scrolling?

Hello, can we have a feature so that when the heatmap is larger than a screen and we scroll the map left-right / up-down, the correspoding labels are still visible? right now suppose i have a heatmap wider than screen width and i keep scrolling it to the right, the xlabels will disappear, making the map hard to read.

No file or test is named. Start by locating the heatmap component's scrolling and label-rendering entry points, then reproduce a heatmap wider and taller than the screen and scroll it horizontally and vertically. Done means the corresponding x and y labels remain visible while scrolling.
