URL of experiment: general issue Description of the problem: Hi all, I have a question and I’m stuck since a few days, because none of the solutions I tried worked. I hope you can help :slight_smile: I have a rating scale that works great offline. As soon as it is uploaded online, the marker is…

Hi Becca, I have found a solution! It is not perfect but it works :smiley: I set the code type to both and entered the following JS code under each frame: if (frameN < 3) { if (Math.random() >= 0) { rating_1.markerPos = Math.floor(Math.random() * 10); } console.log('get marker pos', ra…

Hi There, Thanks for reporting this - that sounds as though “starting value” is not yet implemented in PsychoJS. After trying this locally I actually found I couldn’t set a value in “starting value” did you find this too? Here are a couple of work around demos that I hope might help with your expe…

Hi Becca, thank you very much for your answer and the suggestions. Unfortunately I have not found a solution for the start position. I can’t even try the interactive slider online because I get an error message. I thought it was some little thing and I’m too inexperienced to find it, but it seems t…

[image] vasko: because I get an error message Please could you share with us the error message? do you get that error message when online or locally? Thanks, Becca

Of course, but first it is important to mention that I download the slider, unzip it locally, open it with Psychopy and then upload it to pavlovia. The error message is: TypeError: slider.setLabelHeight is not a function [image] It’s not the only problem though, I think. Best, Vasko

Hi Vasko, Aha I see I think this is using wakes demo which I am less familiar with - were you able to please try the other demo in that thread that I posted? Thanks, Becca

Hi Becca, thanks for the advice. I have indeed tried the slider from wakecarter. Did you mean this slider?: https://run.pavlovia.org/lpxrh6/color_slider_demo Unfortunately, when I download it, it doesn’t run for me both locally and online. Locally I get the error message: …line 168, in startM…

Does this work in 2021.2.3? I’m having issues with my pie chart demo where I want the marker to appear at the start and then change colour and move when you click on a different colour in the chart. https://run.pavlovia.org/vespr/interactive-pie-chart/

Hi Vasko, Thank you for your solution :slight_smile: I was wondering why you put the line ‘if (Math.random() >= 0) {’ in - what does this do? Thank you :slight_smile:

I came up with a different work around. I set the .markerPos setting on the first frameupdate in a code routine. Just set a boolean or a counter in the begin routine section and test it in the each frame section eg > if testcounter == 0 : > testcounter = 1 > volume_slider.markerPos = desir…

Yes, this method should work for setting marker position at the start of the routine. For changing marker color I’de suggest having a look at this Hsv color slider - #2 by Becca
