Ken,

Take a look at the WriteIf function. I think that will do what you want.

Subject: [amibroker] Controlling GraphZOrder on Bar by Bar Basis

 

Seemingly simple one that is not answered in the help files.  Experimenting with bar by bar for loop and if statements does not work either.

 

I would like to plot two simple MACD area plots having similar y axis values.  Assume I make MACD1 Blue in color, MACD2 Red in color.

 

The GraphZOrder puts the first plotted variable on top and when the value of MACD1 is less than the value of MACD2, both are visible (plot in the back is above plot in the front).

 

However, when the value reverses so that MACD1 is greater than MACD2, then MACD2 is hidden from view (behind the area plot for MACD1).

 

Is it possible to "switch" which value is plotted on top so that as the values change, the greater value variable is always behind the lower value variable?

 

Again, my implmentation of a for loop with an if statement did not work.  I used two Plot statements within the loop.

 

Any suggestions?

 

Thanks,

 

Ken

 

 

for (i = 0; i < BarCount; i++)

{

if (MCD1[i] < MCD2[i])

{

Plot(MCD2," [" + WriteVal(Shrt,1.0) + "/" + WriteVal(lng,1.0) + "] MACD",colorRed,styleHistogram);

Plot(MCD1," [" + WriteVal(Shrt,1.0) + "/" + WriteVal(lng,1.0) + "] MACD",colorBlue,styleHistogram);

}

else

{

Plot(MCD1," [" + WriteVal(Shrt,1.0) + "/" + WriteVal(lng,1.0) + "] MACD",colorBlue,styleHistogram);

Plot(MCD2," [" + WriteVal(Shrt,1.0) + "/" + WriteVal(lng,1.0) + "] MACD",colorRed,styleHistogram);

}

}
