Rectangular as line chart markers

[Harald]

Hello,

I am using line chart markers. As I see the built-in types are square,triangle and circle. I need a rectangular as marker, therefore I would need to change the height or the width of the element or draw a rectangular myself and put it as a marker. I only found an option to change the overall size of the square, which didn'tsolve my problem. 

Is there any possibility to achieve this?

Hello Harald,

You can use a custom visual to draw a rectangle - example.

Thank you for this useful code snippet,

I just have two more question regarding these markers:

1) Is there any possibility that when I use zooming, the markers also get bigger or smaller regarding the zoom factor?

2) Whenever I want to hightlight one of those markers, the shape of the highlighted element is a square instead of a rectangle. I am using exactly your code. Do you know which setting could be reponsible for this? I attached a screenshot for clarity.

 

Thank you and best regards

Harald

Hi again,

It is possible to scale the rectangles but you will need to manually track the zoom level. The zoom event can be used for this purpose - example.
The option that is responsible for the highlight element is highlight.visual. Please verify that it returns the correct visual.
