Linear Meter / Bar with ticks

[Jay-b]

Hi Guys.

I’m creating a digital dashboard with ESP32 & LVGL.

I’d love to have a Linear/flat/horizontal/vertical option of the meter.
Like someone implemented here (but now seems to be lost forever)

Widget to draw a linear scale

This is like the linemeter except it is linear, not curved. Sorry about the name but I was working in the existing names. Coupled with a bar it serves as a labeled axis. The chart has some similar logic. [linearscale_v] With a bar and label it makes a display [linearscale_h] The code below will not work unless you add the define to lv_conv.h. And you should update the themes too. /*Linear scale (dependencies: *;)*/ #define LV_USE_LINEARSCALE 1 But I wanted to post this here to see if i…

A bar doesn’t quite cut it, as I’m after being able to use most of the options of the scales element.
Minor Ticks, Major Ticks & Coloured Scale would be perfect.

It seems others have asked about it in the past, so hopefully that shows it’s not just me

Vertical and/or horizontal line meter

The branch(https://github.com/xennex22/lvgl/tree/lv_linearscale) that you mentioned doesn’t exist. Could kindly provide another link with this code.

How to create a linear scale table

Hello everyone, I want to ask why we can’t add straight line scale, for example, let us choose the circle, or the straight line scale, because now we really want the straight line scale, but only through painting.And the calculation is only plastic, because the calculation is floating point, the larger the value, the greater the deviation. Is there a way, can you use floating point painting? Thank you. [1610439245(1)]

I also see the need for that. I’ve just added it to the ROADMAP.
