    @parsureshkumar,

    You can achieve this by adding stripLines and removing axis-labels and ticks. Please take a look at this JSFiddle. You can further customize the look and feel of the chart by changing chart-options according to your requirements.

    @parsureshkumar,

    The JSFiddle shared shows how you can achieve ECG graph using CanvasJS charts, which you can further customize as per your requirements. Here is the updated JSFiddle showing 5*5 graph with minor-grids.

    You can customize the thickness of gridlines using gridThickness, dataSeries line using lineThickness, stripLine using thickness properties.

    Hi
    sorry i was mistakenly said that 5*5 graph
    here i mentintoned the actual response we need.
    we need the ecg lines with actual gap. Updated Canvas Js ECG graph having ecg Live very closed ,
    the graph will be in xaxis based on Data point so that data lines willbe clear with ups and down
    for ex we have maximum 3600 value in x-axis so need the graph will be scrollable (horizontal)

    sample link:
    please refer this link for ecg line space.

    then please share how do we update the 5*5 to 10*10 or custom by user

    #22545

    @parsureshkumar,

    You can customize it to be 5*5 or the desired dimension of yours by updating the interval. In the JSFiddle, 10 stripLines are added between each interval. You can customize it to add more – please try updating the same in addStripLines method.

    Please refer Creating Dynamic Charts for tutorial on rendering dynamic charts.
