Scaling of two indicators in one subplot

Postby javamarket » 11 Aug 2014

Hello all and thanks for any assistance ...

I have an indicator I've used for years that I'm fond of. It has two parts, a primary range plotter and a fib overlay. When I apply this set on a subplot the scaling of the two seems inconsistent. Perhaps I'm missing something basic but I believe there may be an anomaly here. Can anyone else confirm the discrepancy? Code follows:

eKamWhere

Code: Select all

{ how big is today's range, and where are we in that range? }
input:
Comment("");
var: dayRange(0),hi(0),lo(0),
p1(0.382),p2(0.5),p3(0.618),p4(0.786),
bottom(0),top(0),it(0);

hi = HighD(0); lo = LowD(0);
dayRange = hi - lo;
top = dayRange/2;
bottom = -top;
it = bottom + c - lo;

plot1(bottom,"range bottom");
plot2(top, "range top");
plot3(0, "range middle");

var: color(yellow);
if it>it[1] then color=green;
if it<it[1] then color=red;
plot4(it,"now",color);

plot4[1](it[1],"now",color);
eKamWhereFib

Code: Select all

{ plot fib levels within today's range }

input:
fib1(0.214),
fib2(0.382),
fib3(0.618),
fib4(0.786);

var: dayRange(0),hi(0),lo(0),
bottom(0),top(0);

hi = HighD(0); lo = LowD(0);
dayRange = hi - lo;
top = dayRange/2;
bottom = -top;

plot1(bottom + dayRange*fib1, "fib1");
plot2(bottom + dayRange*fib2, "fib2");
plot3(bottom + dayRange*fib3, "fib3");
plot4(bottom + dayRange*fib4, "fib4");
To recreate, I plot this on an @ES and both components are set to 'Same as instrument'. If you'll hover with the cursor and read the data box you should see that the value of one set no longer matches the shared scaling labels of the Y-axis.

The easiest way is to combine the two codes into one single code.

Code: Select all

{ how big is today's range, and where are we in that range? }
input:
fib1(0.214),
fib2(0.382),
fib3(0.618),
fib4(0.786);
var: dayRange(0),hi(0),lo(0),
bottom(0),top(0),it(0),color(yellow);

hi = HighD(0); lo = LowD(0);
dayRange = hi - lo;
top = dayRange/2;
bottom = -top;
it = bottom + c - lo;

plot1(bottom,"range bottom",green);
plot2(top, "range top",red);
plot3(0, "range middle",white);

if it>it[1] then color=green;
if it<it[1] then color=red;
plot4(it,"now",color);

plot4[1](it[1],"now",color);

plot11(bottom + dayRange*fib1, "fib1",darkgreen);
plot12(bottom + dayRange*fib2, "fib2",cyan);
plot13(bottom + dayRange*fib3, "fib3",magenta);
plot14(bottom + dayRange*fib4, "fib4",darkred);

Hi @SB and thank you. I agree merging the constructs sorts it.

The main reason for posting was to perhaps ID a bug.

That said I do appreciate you taking the time to reply and post.

Hello javamarket,

Since MultiCharts 9.0 Beta 1 multiple indicators plotted on the same subchart all set to "same as instrument" scaling have a single "same as instrument" Y-price axis. With such setup in order to change the indicator Y-price axis you need to drag the instrument's Y-price axis.

Hi Henry,

Thank you for the information. I look forward to this change when out of beta.
Basis your description it will solve this.
