double getScreenX(
  1. int i,
  2. int startIndex
)

Converts x-position to screen coordinates. i is data point index. startIndex is starting index for current page. Returns x-coordinate on canvas.

Implementation

double getScreenX(int i, int startIndex) {
  double increment = (pixelsPerOneMM! / timeScaleFactor);
  double k = xOrigin! + increment * 4;
  k += increment * (i - (startIndex * pointsPerPage));
  return k;
}
