Andrew Wade modifies by adding to a previous tutorial on the net for creating dynamic bar charts in After Effects, and in Andrew’s case he needed bars that both travel on the positive and negative values, and here is his tutorial on how to do that.
Andrew Wade writes: “Andrew Kramer over at video co-pilot did a tutorial a while back on creating dynamic bar charts in after effects. I followed this tutorial but I needed my charts to go up and down with both positive and negative values in the chart. I modified his expressions tweaked the animations to suit and created this. So here is how you can go about creating these charts yourself. This technique can be used to control any kind of dynamic data or animation within an After Effects composition and is quite flexible. So if you have any ideas or have created something using these techniques, please leave a comment over at my website andrew-wade.co.uk”
