Fix size of a brick in heatmap

Hi All,
I am new to so please forgive me if my question is too basic.
Is there a way to set size for brick(or a point) in heatmap ? What I observed is the brick size varies depending on the number of data points. More points decreases brick size and less points increases it. For my case I need fixed brick size irrespective of data points. Is there a way to do it?

There’s no way to set fixed brick dimensions at the moment.

You’ll need to adjust your graph’s layout.width and layout.height.

Is that feature available now? I am looking to set a default brick size when there are too many data points which causes the bricks to be too small in size. I want to set a minimum brick size and then enable horizontal scroll bar.
Any help would be much appreciated.
