Plotting the Graph against ECG Modality

[PRITISH]

ECG

I have no previous experience in plotting the Graph. I want to plot ECG Graph w.r.to their Waveform Sequence How it can be achieve and below are some points that also i need to ask....

1)I want to draw ECG from ECG Modality.
2)For this how to draw the graph and what type of co-ordinate i need to consider.
3)which dicom tags are helpful to draw graph w.r.to to point to draw

(5400, 0100) Waveform Sequence

1) "5.6.3-9-1", // "I"
2) "5.6.3-9-2", // "II",
3) "5.6.3-9-61", // "III",
4) "5.6.3-9-62", // "aVR",
5) "5.6.3-9-63", // "aVL",
6) "5.6.3-9-64", // "aVF",
7) "5.6.3-9-3", // "V1",
8) "5.6.3-9-4", // "V2",
9) "5.6.3-9-5", // "V3",
10) "5.6.3-9-6", // "V4",
11) "5.6.3-9-7", // "V5",
12) "5.6.3-9-8", // "V6"

4)How to plot the graph intervals along with (X,Y) axis and which values are shown over the graph from which dicom tags are necessary to show ECG values over graph.

give me details that are necessary for ECG modality (i.e. the relationship between the ECG tags that need to follow).

Thanks for reply
