Days of week on intraday chart by changing the background color

[simon]

Hello @Tomasz ,

I would like to find a color for a day and another color for the next day when I am in 15-minutes timeframe. I found a similar post and tried to deal with it:

How to visually identify days of the week on intraday charts? Background color change for each separate day

hi milosz thanks a lot for taking so much effort. my backgrd color is white , in the code because black is mentioned the system is painting the background black, i tried diff combinations, in all cases the color is the one instead of black. i tried changing z order but the problem still exists. your other alternate codes are fine and dau no and week day name are working perfect thanks once again regards nitin bagadia

So, I changed the "Minimum spacing (px)" to 200, but the problem is that sometimes it works and sometimes doesn't. For example, in the following picture, it works well:

Now, if I shift the chart a little to the left, it doesn't work:

Could you please help me in this regard?

Best regards,

To draw week days in background you should draw YOUR OWN background, instead of specifying some fixed pixel sizes. Internal grid layout engine is doing lots of effort to keep axis good looking. Having just 1 number in entire X axis looks bad and that is what you would get in second screenshot if there were no finer X ticks. AB prevents that.

As I wrote - draw your OWN background, using either Gfx functions

or plain Plot() function with styleArea.

If you used search before posting: https://forum.amibroker.com/search?q=own%20background%20colors

@n_bagadia you might use this code: FirstBar = DateNum() != Ref( DateNum(), -1 ); RibbonColor1 = ColorBlend( colorBlack, colorGold, 0.1 ); RibbonColor2 = ColorBlack; RibbonColor = IIf( Cum( FirstBar ) % 2 == 0, RibbonColor1, RibbonColor2 ); Plot( Close, "Close", colorDefault, styleCandle ); Plot( FirstBar, "", colorGold, styleHistogram | styleOwnScale | styleNoLabel, 1, 0, 0, -1, 2 ); Plot( 1, "", RibbonColor, styleArea | styleOwnScale | styleNoLabel, 0, 1, 0, -1 ); If you don't need vertical …
