Drawing functions Q

[mbuta]

Hi,

Is there a way to keep a Text/Shape etc. at fixed distance [in pixels] from, say, high or low of a bar?

For Example, y=High(offset)+15 Pixels.

Apparently [from Doc/Help], DrawRelative does not accept Pixels in y calculation and DrawPixels does not accept a price reference.

Thank you.

Hello Mihai,

With the release of EFS2 there were two new functions added to allow users to accomplish this very task, drawText() and drawShape(). Although these functions do not allow you to specify a specific pixel amount for the spacing they do give you four locations above the bar and below the bar.

AboveBar1
AboveBar2
AboveBar3
AboveBar4
BelowBar1
BelowBar2
BelowBar3
BelowBar4

In addition to these 8 locations, you also have 8 more locations that are relative to the top and bottom of the window. These are referred to as the top rows and bottom rows.

TopRow1
TopRow2
TopRow3
TopRow4
BottomRow1
BottomRow2
BottomRow3
BottomRow4

Here's a basic code example.

function preMain() {
        setPriceStudy(true);
}

function main() {
        drawText("X", AboveBar1, Color.blue, null, "abar1"); 
        drawText("X", AboveBar2, Color.blue, null, "abar2"); 
        drawText("X", AboveBar3, Color.blue, null, "abar3"); 
        drawText("X", AboveBar4, Color.blue, null, "abar4"); 

        drawShape(Shape.CIRCLE, BelowBar1, Color.blue, "bbar1"); 
        drawShape(Shape.CIRCLE, BelowBar2, Color.blue, "bbar2"); 
        drawShape(Shape.CIRCLE, BelowBar3, Color.blue, "bbar3"); 
        drawShape(Shape.CIRCLE, BelowBar4, Color.blue, "bbar4"); 

        return;
} 

Try replacing the location constants with the TopRow or BottomRow constants to see what that looks like.

Jason,

Thank you.

I did try to use DrawText/DrawShape and, as expected, they do not take BarOffset as parameter. Draw all Shpes/Texts at the last bar.
I also tried to use those [very good] parameters in DrawRelative but does not work either.

Is there any other way?

Thank you.

Yes, you can use the AboveBar and BelowBar constants with the drawTextRelative() function.... you just need to 'activate' that functionality by using the Text.PRESET flag. Example:

drawTextRelative( 0, AboveBar1, "B", Color.red, null, Text.PRESET | Text.BOLD, null, 12 );

Thank you Chris,

Now I saw it in the Help also.

Note: I may not be to bright, but would not hurt [given that many of us are not "proffessional coders"] to make it more explicit than it is now.

If nothing else, some examples showing the use of NEW features like this, is a minimum

For one, I know I tried to understand it, but could not, although I have a good track record of reading specifications [former computer architect for IBM mainframe storage systems].

Additional Note: I see Shape.PRESET is not mentioned at all. I assume it is available!


Thanks again,
Mihai

Sorry, but could not make it work.
I use the same line as before just replaced the "y" and changed Flags to include .PRESET.

It works if I "manufacture" y from high/low, does not when use AboveBar/BelowBar.

Shape.PRESET is mentioned in both drawShapeRelative() and drawShapeAbsolute()

Hello Mihai,

The code snippet Chris posted works fine. Please post the code you are using so we can see what the difference might be.

[mbuta]

Jason,

I copied Chris' line directly in my efs and does not work.


Alex,

There is no Shape.PRESET in my Help file.

But, I am using 7.91 Buid 738 which might be the cause.

Unfortunatelly, eSignal does not alert its users [like all respectable programs] when they are using an outdated version!!!

I will report if that was the problem.

Thank you,
Mihai

1. I did upgrade to 8.0 but the problem is not solved.

2. Not plotting correctly of AboveBar/BelowBar was a known bug and was supposed to be fixed in this version.

3. My Help file [I am talking about the file that opens with "?" from EFS Editor] still does not have Shape.RESET.

This tells me that either [a] the bug was not fixed, or [b] not all files, particularly those pertaining to EFS are not updated.

I don't know what else to do. My EFS it is fine, for sure.

Note: Simple problem that should take no time to solve, takes forever!!

I did even more: unistalled eSignal, deleted eSignal directory, re-installed eSighal, still same result and Shape.PRESET in not in my Help file.

I don't know what you guys are looking at, but whatever it is, apparently, is not available for general public [unless I am doing something very stupid here].

Out of curiosity: How did they know to recover my old Time Templates, which I forgot to save before deleting s/w?!?!
[I did save Formulas and Pages]

That information is in the EFS KnowledgeBase and is available to everyone.
See drawShapeAbsolute() and drawShapeRelative()

Alex.

I am not using Knowledge Base. I am using EFS Editor and there, it is not. And AboveBar/BelowBar don't work from Version 8.0 downloaded from eSignal website.

I would be gratefull to anybody who has an working example of using AboveBar/BelowBar using the same version of eSignal available to us [downloaded from eSignal site].

Thank you very much.

[dloomis]

did you try

drawText( "Buy", BottomRow2 );

that probably doesnt help either.

AboveBar/BelowBar work fine at my end using version 8.0 (build 779) downloaded from the web site
If it is not working with your code then post your code as indicated in the PLEASE READ: Posting Guidelines for EFS Studies Forum
