To explain better what I need, think about a tank and a can of soda.
No matter what the speed of that can of soda would be, the tank wouldn't move if it's hit.
But the tank should be able to move when force is applied to it.
Already opened an issue here with more details:
https://github.com/liabru/matter-js/issues/841
And I also made an example here for what I need.
var Engine = Matter.Engine,
Render = Matter.Render,
World = Matter.World,
Bodies = Matter.Bodies,
Body = Matter.Body;
var engine = Engine.create();
engine.positionIterations = 10;
engine.velocityIterations = 8;
var render = Render.create({
element: document.body,
engine: engine,
options: {
width: 800,
height: 400,
wireframes: false
}
});
engine.world.gravity.y = 0;
var topWall = Bodies.rectangle(400, 50, 720, 20, { isStatic: true });
var leftWall = Bodies.rectangle(50, 210, 20, 300, { isStatic: true });
var rightWall = Bodies.rectangle(750, 210, 20, 300, { isStatic: true });
var bottomWall = Bodies.rectangle(400, 350, 720, 20, { isStatic: true });
var ball = Bodies.circle(100, 200, 5, {
friction: 0.05,
frictionAir: 0.05,
density: 0.001,
restitution: 0.2
});
var bigBox = Matter.Bodies.rectangle(500, 200, 120, 120, {
inertia: Infinity,
frictionAir: 1,
friction: 1,
density: 0.1
});
World.add(engine.world, [topWall, leftWall, rightWall, bottomWall, ball, bigBox]);
Engine.run(engine);
Render.run(render);
// CMD + SHIFT + 7 to reload
$('.shoot').on('click', function () {
var speed = 0.02;
var angle = 0;
let vector = Matter.Vector.create(Math.cos(angle) * speed, Math.sin(angle) * speed);
Body.applyForce(ball, ball.position, vector);
});

I would love to know if building something like this is possible is RShiny. I have experience with interactive plots/charts using plotly, ggplot and ggplotly but I can't see how to do something like this. I love how the graph engages the user to make a guess and then shows the real data.
If anyone could please point me in the direction of any documentation I will be forever grateful!

'showgrid': False, # thin lines in the background
'zeroline': False, # thick line at x=0
'visible': False, # numbers below
}, # the same for yaxis
also if you want to remove the legend:
layout = {
'showlegend': False,
...
To turn off axes in newer versions:
#legend
fig.update_layout(showlegend=False)
#x axis
fig.update_xaxes(visible=False)
#y axis
fig.update_yaxes(visible=False)
I am using oxyplot to plot a bar chart. I wish to add an extra label in the chart. I've tried to use Textannotation but it's not showing on the chart. What is the mistake I'm making to cause the text not to appear, is it the DataPoint? Please help.

Title = "Daily",
LegendPlacement = LegendPlacement.Outside,
LegendPosition = LegendPosition.BottomCenter,
LegendOrientation = LegendOrientation.Horizontal,
LegendBorderThickness = 0
};
TextAnnotation txtlabel = new TextAnnotation();
txtlabel.Text = "Test";
txtlabel.TextColor = OxyColors.Red;
txtlabel.Stroke = OxyColors.Red;
txtlabel.StrokeThickness = 5;
txtlabel.FontSize = 36;
txtlabel.TextPosition = new DataPoint(21, 3.5);
plotModel.Annotations.Add(txtlabel);
