Duplicated: Carto DB: Scalable points over time using Torque in Carto DB

But, basically you need:

1. Edit the torque-aggregation-function in the CartoCSS. From count(cartodb_id) to, for example, avg(your_value_column_name)

2. Then, you'll be able to use the variable value that will be equal to the avg of the values that lay inside the aggregation region you've selected. Don't worry about this too much because your points seem separated enough so that they doesn't collide.

Example:

/** torque visualization */

Map {
-torque-frame-count:16;
-torque-animation-duration:10;
-torque-time-attribute:"time";
-torque-aggregation-function:"avg(value_column_name)";
-torque-resolution:2;
-torque-data-aggregation:linear;
}

#torque_sizes_ex{
comp-op: lighter;
marker-fill-opacity: 0.9;
marker-line-color: #FFF;
marker-line-width: 1.5;
marker-line-opacity: 1;
marker-type: ellipse;
marker-width:[value]/10 ;
marker-fill: #FF9900;
}

Of course, you can edit the rest of values as the frame-count, duration, etc as your convenience.
