You must have at least 500 SP voting power to do that. Then you will see a slider like the one you see in Steemit. I am showing an example of that slider below:
You can change the voting power by changing the round cursor. When you change the position of the round cursor, the slider will show a number which represents the percentage of your vote.
I think you can only control your voting weight when you reach 500 sp and above
It's the same with steemit.
If you really want to control your voting weight and you have less than 500 SP, then you should conservatives using busy.org. they allow everyone to use an upvote slider
I hope this helps
Unfortunately, like the Steemit.com frontend, Musing.io only allow users to adjust their voting percentage once they have 500 STEEM Power and up. If you have below 500 STEEM Power, you are limited to 100% upvotes.
So, if you want to adjust your voting percentage, while you still have below 500 STEEM Power, you can do one of two things:
First, you could vote using a different Steem frontend. Unlike Musing.io other Steem frontends like Steempeak.com, Busy.org, or Partiko actually allow all users to adjust their voting percentages. Keep in mind, though, that unlike other Steem frontends, Musing.io's link structure is a little different, so it's not as simple as replacing the "musing.io" domain with another frontend's domain. So, to be sure you're voting on the same answer or question, always check the page's permlink.
Another way to upvote using different percentages is to setup an auto-vote like with SteemAuto.com. I have actually received a few votes from other users, who I suspect is using this feature.
Hope this helps.
(Note: I updated the answer to correct the inaccuracy pointed out in @littleboy's comment below.)
There is no option for that on this platform. However, I use partiko app and I get notifications when someone replies my questions. It appears that all the questions and answers are posted on the blockchain in form of a thread or chain on @musing-threads. So you can see it-- the questions you asked and those of other users, and you can upvote the ones you like. Partiko gives you the option to adjusting your vote weight before voting, so you can do that and earn something from the curation reward as you support others. However, I feel some users have started to abuse this function.
There is no slider for upvoting here at Musing website. However, if you are at Steemit, there is a chance you can upvote Musing posts with any percentage you want to give depending on your Steem Power. If you use busy.org or Partiko app, you can adjust percentage of upvote if you want to upvote Musing posts regardless of your Steem Power.
The requirement for you to have a voting Slider with Steemit (which Musing has technically followed the original algorithm) is 500 Steem Power. This will allow you to scale your vote percentage when voting.
Below 500 Steem Power will not give you any voting slider mainly because it has almost no value at all. It's ironic to scale an almost no value vote. So if a user wishes to have a voting slider, he/she needs to power-up or be delegated with at least 500 Steem Power.
For questions I d not know.
However if it is to a comment, This can be done by looking at the comments a person makes by logging in through Steemit or Steempeak. or other entry point to the platform.
You can see a persons comment there and vote to them using a slider. On musing itself I do not know of a way to adjust your voting power and I am assuming that those votes you see at a % are done by people voting on comments through a different entry point to the platform.
If you log into Busy.org or Steempeak.org and have a look at your comments you will see them there too. It looks to me like this is what you are seeing when you see a % other than a vote from Musing and staff.
If this is not the case, Some have a bot the rest of us do not know about for voting to musing comments and posts.
You need to hold a certain amount of SP or higher to get the option. I get an upvote slider on musing.io. There's nothing wrong with that. Less % in upvotes also means more upvotes to give.
It's easy. I make use of my laptop to ask and answer questions on Musing. Whenever I want to upvote any question or answer, I click on upvote question/answer and I immediately see a pop up slider, then I reduce it to whatever percentage I want to give. You have to really look closely to find out the exact percentage number because it immediately disappears once the percentage value shows up.
This is very simple and easy to explain.
When you click on upvote question or answer it then uploads a slider. Click on the slider and move it to the percentage you want to vote for.Once you have decided on this click on vote and that will be the percentage you vote on.
We just have to be careful that we are voting with enough percentage so our vote counts and doesn't disappear to the vote tax.
I hope this helps.
