Passing variables to drawtext & drawline

[sajones]

Is it possible to pass a variable describing the line format to the drawline function?

It seems to work fine when using numbers e.g. the thickness of a line but not for a text base parameter e.g. PS_SOLID or the name of the line or text itself.

I get the error "Parameter Number 5 of Function drawLineRelative is invalid". I've seen this parameter passed into the main part of the code as a function parameter but my requirement is necessary to change the appearance of a line say from PS_DASH when a target but to PS_SOLID when target is reached.

I have tried having two different drawline commands within an if statement, one with PS_DASH and one with PS_SOLID but I get half a length of line dashed before the condition was met and half solid after the condition was met but at a different price. Perhaps that is a different coding issue but it would be nice to retain the same code for both and pass a parameter to the function.

It is possible by enclosing the variable in an eval() function to evaluate the string (see example enclosed below)

var myParameter = PS_SOLID;
    
drawLineRelative(-10,close(0),0,close(0),eval(myParameter),1,Color.red,"line");
