wish: lower line graph interval to display more dots

At first your title is not accurate : there is no distortion but only different option of display with show/hide empty lines, so when the balance has no variation.

The minimum zoom is currently set to 8 item width, mostly because for bar less than that make then not distinguishable each.

So indeed if you like to display a 2 years by days it will requires only for the graph area 365*2*8 pixel, so 5840 pixel wide, event a 4k display (3840) will not.

So at the end what you would like is to lower this minimum for line graph to display more dots.

When I wrote "distortion", I meant only that the X scale is not linear when 'Show empty line' is not checked. For example, if the X axis looks like this:

  Dec 1 '22 Jan 1 '23 Mar 1 '23 Apr 1 '23
    | | | |
    A B C D

I would call that distorted, because the distance in time between points A and B (1 month) is not the same as the distance in time between points B and C (2 months), even though the physical distances are the same. Instead, you could draw the graph like this, putting more horizontal space between points C and D:

  Dec 1 '22 Jan 1 '23 Mar 1 '23 Apr 1 '23
    | | | |
    A B C D

Then the display would be linear, i.e. not distorted.

In any case, lowering the minimum zoom would also help, since then I could choose 'Show empty line', which gives a linear display, and then zoom until the entire graph is in view. You wrote "mostly because for bar less than that make then not distinguishable each." Well, you don't necessarily need to draw a pixel for every day. Suppose that the graph spans 10 years, which is 3650 days, but the window is only 1000 pixels wide. You could choose to draw one pixel for every 3.65 days, skipping the intervening days. That might look better.

p.s. The pictures that I attempted to draw in ASCII above didn't come out right - I didn't realize that Launchpad would replace sequences of spaces by a single space. I'll try again, using dots instead of spaces. Here is the distorted, non-linear view:

..Dec 1 '22.......Jan 1 '23.......Mar 1 '23......Apr 1 '23
......|...............|...............|..............|....
......A...............B...............C..............D....

Instead, you could draw each dot at an X-position proportional to its time:

..Dec 1 '22...... Jan 1 '23..................... Mar 1 '23.......Apr 1 '23
......|...............|..............................|..............|....
......A...............B..............................C..............D....

Yes, I understood you right.

The purpose of "show empty line"=off is to get only relevant dots to display useful ones only, so yes it is not time accurate,

if I introduce what you suggest the gain is no more there, only the "show empty line"=on is time accurate as it shows all interval stops, but require depending on interval a lot of width.

proportional is useless here as it will require the same width than "show empty line"=on...

SO the only way to draw more dots is to reduce the interval, is this will suit your wish ?

When you say "reduce the interval", do you mean increasing the maximum possible zoom level controlled by the "Zoom X" slider, so that I can zoom in more than now? If so then yes, I think that will help because then I'll be able to see the entire graph without scrolling, with a time-accurate display.
