I have a line chart which shows multiple lines. X-axis represents date and Y-axis represents numeric reading. The lines represent the category PZ-1, PZ-2 & PZ-3. I have managed to remove the horizontal line that connect between the dots but now I want to connect the dots vertically that aligns based on the date on X-axis. I do not want to rotate the line or swap X-axis position with Y-axis and vice versa. Does anyone know how I can achieve the vertical line? Thank you
Below is my current code:
const data = {
datasets: [
