    Your line chart is breaking because your data points are not contiguous regarding the x-axis scale.

    Maybe switching on the interpolation function will help because that'll give you a continuous line. Search for it in the forum, it should be simple to find examples.

    Thank you for reply @pamval

    According to your suggestion. I searched for interpolation function and i did find '
    nullInterpolationMode' and i set it as linear. And now i am getting this chart

    Now it is not exactly what i wanted, but its better than before.
    is there any way we can convert these dotted line into solid lines.
    Thank you

    line_strokeDasharray: "none"
    and now i got what i wanted.
