RE: [amibroker] Help with Log Scale Plot

Hi Al,
 
After taking a little look at 
the problem I can't see a way to do this. That's not saying there is none just I 
can't see it. You would have to be able to scale the y-axis just like the 
inbuilt (IB) logarithmic option does and there is not such an option or any 
way to emulate its behaviour.

Hi Al,
 
Here is template I use to set 
up custom grids, from this you should be able to create the grid and plot the 
price scale your after. I'm a little busy right now but if you haven't been able 
to write the codeit or someone else can't help, ill take a look tomorrow.

Help with Log Scale Plot
William or Ken:
 
This is not directly related to your question, but a couple of 
weeks ago, I posted a question and did not get any response. I'd like to know 
how to get a log base 10 plot rather than a log base 2. Anyone know how to do 
this? 
 
TIA.

  Scale PlotSorry for such a basic question (and revealing some 
  continued frustration with the help searching capability), but all I want to 
  do is plot a parameter with the y scale as a log scale.//  Nasd New 
  Highs/New Lows 
  IndicatorNH=Foreign("NSNHQ","C");NL=Foreign("NSNLQ","C");R=NH-NL;Plot(R,"Net

  plot but nothing changes when I apply this.  I even added the last line 
  to see if the scale would change, but it did not.What am I doing 
  wrong?Thanks,KenPS: The foreign calls are to symbols within the FT 
  database. The thing plots fine, just with a linear scale.  Where is 
  plotting the log scale explained as I really did search trying to find 
  it.Send BUG REPORTS to bugs@xxxxxxxxxxxxxSend SUGGESTIONS to
