Replace lines drawing canvas for custom lines?

hi its there something extension or form to replace the lines for custom lines?

can you elaborate

elaborate my custom lines?. but its possible replace the default lines?. if its not possible, i need to make my extension no?

What do you mean by custom lines?
Maybe you need to set line color/width, and clear the vanvas, and redraw the line again.

Look in the Canvas component to see the blocks that will set line width, color, etc. for subsequently drawn lines.

my question is about change the style of lines to other lines with other lateral line form. one example. a line with arcoiris colour or with other textures.
