Following this, I tried to add labels to the arcs but It is not working as I expected. My code:

view := RTView new.
shape := RTArc new
    innerRadius: [ :i | i *50];
    externalRadius: [ :i | (i * 50) + 4];
    alphaAngle: 45;
    betaAngle: 135;
    color: Color black.
elems := shape elementsOn: (1 to: 2).
view addAll: elems.

label := RTLabelled new text: #yourself.
label left.
elems @ label.

view

and the results is the attached image.

I want the labels to be at the left of the arc line. Maybe I'm doing something wrong? any ideas?

Bests,

Miguel

I want to add labels first,  after that I'm going to publish a video. :)

Here is the screenshot, it is a visualization from the data captured from a laser scan sensor from a robot.

The visualization shows an object with the red line and a grid to understand quickly the position of the object within the range of the sensor (This case, the object is approximately in the center between 2 to 4 meters from the robot) . The visualization is dynamic, ie: the red line is automatically updated overtime ;)

Thanks!

Both seem to work fine, I'm going to play a bit before deciding for one :)

You can also use bezier lines or SVG

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

| v e1 e2 l s p1 p2 path svg|

v := RTView new.

path := 'M -150 150 Q -75 150 -75 75 Q -75 0 0 0'.

svg := RTSVGPath new borderColor: Color red; path: path; element.

v add: svg.

Try with RTArc:

view := RTView new.

shape := RTArc new

innerRadius: [ :i | i *15];

externalRadius: [ :i | (i * 15) + 4];

alphaAngle: 45;

betaAngle: 135;

color: Color black.

view addAll: (shape elementsOn: (1 to: 11) ).

view

Hi all,

I want to draw curved lines in Roassal but I can't find how to.

The image below is an example of what I am trying to do.
