@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.

Hi
This grap is looking fine,we are expecting 60 secs of ecg graph (3600 points in x-axis) with scrollable.
for both x and y axis like 5*5 graph 0 to 4 line thickness :0 5 line thickness :1 6 to 9 line thickness :0 10 line thickness :1
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
Hi We got out put but strip line were disappear while customizing the ECG Please advice on this FYI
image link https://ibb.co/g591h9
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.
How can we make it feel like real time, I tried to add a setTimeOut in loop but it didn’t work
@ahhsan,
Please check out this forum thread for more information on rendering dynamic chart for ECG along with an example.
If you are still facing issue, can you kindly create JSFiddle & share it with us so that we can look into the code, understand the scenario better & help you out?
