Is ECG chart possible using JSCharts? February 17, 2011 07:19AM |

Is ElectroCardiogram chart possible though JSCharts? If so, how? There will also be a thick vertical bar in the middle of the chart , which when dragged will update other charts like Heart Rate, Activity level. In short, the Heart Rate and Activity Level charts will show zoomed in data of that vertical bar. Is this possible using JSCharts?
Also the ECG chart needs to be horizontally scrollable for the total width of x-axis. Only a fragment of total x-axis will be visible at given time.

I guess it's possible for a JavaScript programmer to create a draggable div over the chart and make the other features you mentioned. But otherwise this is not possible directly in JS Charts.

Suppose I use scrollable div tag as container that provides horizontal scrolling for the chart.
Will I be able to plot absolute points on x-axis and y-axis. As shown in the figure at below URL
ECG basics
one square means 0.20 seconds on x-axis
one square means 0.5 milivolts on y-axis
so, my y-axis will be approx. 4 milivolts in height.
my x-axis will be approx. 180 seconds in width (but only 15 seconds visible at a time, rest by scrolling)
So, will I be able to plot absolute points on x-axis like 0.20, 0.40, 0.60 seconds and so on? same goes for y-axis like 0.5, 1, 1.5, 2.0 milivolts.

You mean if there is a problem using floating numbers? Or that the axes are not the same scale? These should be no problem, as long as the increment is linear (somebody asked if we support logarithmic scales, we do not).
But the grid as shown in your example cannot be done directly in JS Charts, with a thick line every 5 lines. For that I would try to use a background image and not use the JS Charts grid at all.

as per requirement, we can skip thin lines and only plot thick lines.
By absolute points on axis, I mean, will I be able to have these values of x-axis 0.20, 0.40, 0.60 where a vertical thick line would be present.
on y-axis, values will be 0.5, 1.0, 1.5 where a horizontal thick line would be present. These thick lines would form the grid.
Plotting of points in the graph area is another thing.

You mean the values should repeat every thick line? In this case you can use setLabelX and setLabelY (mentioned in your other post).
