Linked Sliders - The Easy Solution for Complicated Models

Linked sliders are a set of sliders which are linked to sum up to 100% by default. Each time you change the value of one slider, the slider underneath it will be affected accordingly too. If you don’t want a particular slider to change anymore, you can simply click the small lock on the left to lock the current value.

For example, take the market share of four different drugs. If one drug gains market share, at least one of the other drugs must lose market share accordingly. Why don’t you just play around with the linked sliders below to get an idea of how they work?

Now to show you the full potential of linked sliders, take the model below as an example. This second example uses two separate sets of linked sliders to show a more complex situation and allows you to play around with all the important factors in one model. The values of both sets of linked sliders are used to calculate unemployment payments for several groups. It shows the population of a generic town and the distribution of their inhabitants regarding the labor market. With the sliders, you can set the value of people receiving pensions, the employed workforce, the unemployed [further divided into people receiving money from unemployment insurance (benefit 1), people receiving unemployment pay (benefit 2), and people not receiving federal money], and the population currently in training.

Within the linked slider properties, you can change the exact value of each group as well as change the format from percentage to number. Set the sliders to the desired number of people in any group and click the lock symbol to lock the number. Once you have set each slider to the appropriate value, you can move on to the second set of linked sliders, which then gives the percentage of unemployed people receiving either benefit 1, benefit 2, or no benefits at all.

Once all of the values are set, you can see the total number of people receiving benefit 1, benefit 2, or no benefits in the section below the sliders. You could take the example even further by dividing the unemployed people who receive benefit 1 and benefit 2 into several groups, possibly according to the length of unemployment.

Complex Models on One Page

As you can see, linked sliders allow you to create complex models with lots of factors on just one page. They are easy to implement and offer enough flexibility to adapt them to almost any need, and most importantly - once your models are created, they are easy to use.
