Returns the X and Y values of a series from a specified Y value.
FINDVAL(series, val)
(x, y) = FINDVAL(series, val)
series |
- |
A series. |
val |
- |
A real or series. The values to search. |
An XY series or separate scalars:
b = FINDVAL(series, val)
returns an XY series.
(x, y) = FINDVAL(series, val)
returns the X and Y values as separate scalars.
a = {1, 12, 0, 5};
b = findval(a, 0);
(x, y) = findval(a, 0);
b == xy({2}, {0})
x == 2.0
y == 0.0
W1: gnorm(100,.1);overp(findval(curr,max),lred);setsym(CIRCLE,2)
marks the MAX of W1 with a red circle.
FINDVAL returns an XY series with the same units as the input series. Multiple x values can be returned if val occurs multiple times in the series.
(x, y) = findval(series, val) returns the first occurrence of val in series.
