It’s perfect!! Thank you Dan

One thing I noticed is the Y position height is constant. Is there a way to randomize the rampValue to achieve a different height each time and maintain the triangle shape? I tried to add a wiggle to the value, but not only does it change the heigh but also the shape.

That works perfectly! I can adjust the rampTime to create a more triangle wave look or turn it way down to get a more square wave. Thanks again, Dan! Screenshot shows designer artwork under the animated emitter with your expression added to the emitter’s position property.

You’re right! I guess I can’t copy/paste graphics into a post. I would think no more than 5 dots would be needed to make a variety of little graphs like these.

I got this one from Dan Ebberts website https://www.motionscript.com/
You can adjust the values to whatever you want for the range. I have some arbitrary numbers in there from whatever values I needed the last time I used it.
segMin = .3; //minimum segment duration
segMax = .7; //maximum segment duration
minVal = 50;
maxVal = 200;
end = 0;
j = 0;
while ( time >= end){
j += 1;
seedRandom(j,true);
start = end;
end += random(segMin,segMax);
}
s = random(minVal,maxVal);
endVal = [s,s];
seedRandom(j-1,true);
dummy=random(); //this is a throw-away value
s = random(minVal,maxVal);
startVal = [s,s]
ease(time,start,end,startVal,endVal)

Thanks Dan! I tried inserting Math.floor in various places in the expression but I don’t understand the expression enough to modify it like that. This works perfectly 😀

Hey Dan,
I used a “counter with slider” expression I believe you wrote a while back to hook up the text value to the slider so I could round off the decimals and use the prefix MPH. Where would you add the “convertSpeed” linear function to that expression? Or am I going about this wrong?
slider = thisComp.layer("Speed Control").effect("Speed")("Slider");
numDecimals = 0;
commas = false;
dollarSign = false;
percentSign = false;
s = slider.value.toFixed(numDecimals);
prefix = "";
suffix = "MPH";
if (s[0] == "-"){
prefix = "-";
s = s.substr(1);
}
if(dollarSign) prefix += "$";
if(percentSign) suffix = "%";
if (commas){
decimals = "";
if (numDecimals > 0){
decimals = s.substr(-(numDecimals + 1));
s = s.substr(0,s.length - (numDecimals + 1));
}
outStr = s.substr(-s.length, (s.length-1)%3 +1);
for (i = Math.floor((s.length-1)/3); i > 0; i--){
outStr += "," + s.substr(-i*3,3);
}
prefix + outStr + decimals + suffix;
}else{
prefix + s + suffix;

From the behavior you’re describing, it sounds like you have the Rotobezier button checked on the toolbar.

If it’s a solid color, you could simply just replace it with and AE solid. I have this problem with Illustrator as well.
