Canvas class scroll

New comment
 

Is it possible to fix canvas size to half of datas dimension and to set a scroll on the orizzontal axis?

Here I attach a code which can set as input canva size. If canvas size is bigger than datas size no problem, othervise the chart doesn't display correctly. I'd like to have a scroll function to move data on canvas when datas size is bigger than canvas size. Is it possible? If yes is there any example?

Thanks in advance

As far as I know it is not possible

Bitmaps are not scaled in metatrader bitmap handling - at least that was the case I was testing them the last time, and the only way to make them smaller was to resize the source bitmap itself - no "soft way" to do that was possible

 

I found an example where they can scroll text on a canvas creating a OBJ_RECTANGLE_LABEL (Rectangle Label) (https://www.mql5.com/en/articles/751), but I'm not sure you can do the same with chart lines.

The OBJ_RECTANGLE_LABEL and OBJ_BITMAP are completely different types of animals. Not possible to handle them in the same way
