Under chart mode, the y axis is not allowed to be set to column D (1). This is because for the y axis, the maximum allowed number of subcolumns in a densematrix column (D) is 10. On the spreadsheet, user can zoom to a region with <=10 subcolumns, however, the current chart.js code does not take that under consideration. The goal is to modify chart.js to consider zoom status, and if the number of subcolumns is less than 10, allow it to be used for y axis in the second example (https://xenabrowser.net/heatmap/?bookmark=afb724ece938801a4773f43f165f42db).

Hi, I want to help, but I can`t understand what am I need to do.
I checked these two links and I saw that in the second link in the column D seven subcolumns, they are displayed on the X-axis. They should be displayed on the Y-axis if them less than ten, right?

No it is not.

That's the goal to achieve for this issue. But it is not yet.
