DrawRegion

[bobmike]

Hello all,
I'm trying to fill in the area between 1275 , 1270 on E-mini chart
so i used
DrawRegion("tagzone", CurrentBar, 0,1270,1275, Color.Empty, Color.Lime, 2);
but it is not working , what should be the correct code ?
Thanks

DrawRegion requires a DataSeries for one of the parameters, not two double values.

Instead you would want to use DrawRectangle.

DrawRectangle(string tag, bool autoScale, int startBarsAgo, double startY, int endBarsAgo, double endY, Color color, Color backColor, int opacity)

When I use DrawRectangle, the rectangle is clickable and movable, and I DON'T want that , any other idea?
Thanks

Create yourself a DataSeries that contains only 1275 as the value and then use DrawRegion.

Where is the manual of DataSeries ? or/and if possible show me an example of creating DataSeries and using it with DrawRegion to fill in the area between 1270,1275 on ES chart
Thanks

Hi bobmike,
did you get it working ?
I am also interested in the idea of coloring price-areas.
Thanks for info

max-td,

It will work as advertised. You create a DataSeries that holds only one value throughout every bar. Then you just use DrawRegion() to color between that DataSeries and the second value.

Thanks for the explanation !

after trying some things - got really no idea how to create this with DataSeries.

If i use something like this :

DrawRectangle("tag1", false, 10, 3280 - 1, 0, 3250 + 1, Color.Green, Color.PaleGreen, 2);

what do i have to do to start this ?

Max, I also faild to use DataSeries, and I don't wanna use DrawRectangle as the recangle will be clickable and movable, so it ended up doing a trick. by drawing multiple lines using a loop , so when u see them u think it is a zone , but in fact they are lines ,
I wouldn't do that in a programing language i'm familiar with.

You said the same thing in another post in this thread. the examples in that page are not enough, at least from my point of view

Sorry bobmike. I did not see your post come in after max-td's. The original 1st instance was for you and the second was directed to max-td. Now that you have come back and directed further questions I can help you more.

To create a DataSeries you need to follow the steps outlined in the Help Guide link.

In the Variables region of the code

private DataSeries myDataSeries;

In the Initialize() method

myDataSeries = new DataSeries(this);

In the OnBarUpdate() method

myDataSeries.Set(1200);

1200 is whatever value you want the DataSeries to take up as.
To use this in your DrawRegion() you do this:

DrawRegion("tag1", CurrentBar, 0, myDataSeries, 1225, Color.Blue, Color.Green, 2);

1225 is your second value for where you wanted to draw the region to.
You will effectively have a region drawn between 1200 - 1225.

Hi again,
i also tried it with the posted page about the dataseries + found no working example for the problem- so i asked again- well...
Josh - the things you posted now work fine - no problems - nice colored region
I doubled it and now i have 2 choosable regions.
Next step for me would be to create some variables to choose the values for the region when inserting the indicator - instead of having it fix in the code.

Tips for that are welcome!
I m gonna post the indicator when its done.

Josh - is there also an online seminar for basic NinjaScript programming like the seminar for strategy development in your footnote ?
