Dear Echarts support! I've just started to use echarts and I'm facing a problem that I cannot solve and I'm not 100% sure that it is possible to solve with echarts. I would like to create a simulation of an ECG chart with the grids in the background. [image: image.png] It would be important for me that grids should represent proper squares in any case even if we zoom in or out. Thanks for your help in advance.
Best regards, Levente
