Fast Summaries Re-revisited

My recent “Virtual List on Steroids” presentation at DIG-FM, and the preparation of a revised version to give at dotFMP next week, has prompted me to reconsider certain assumptions re: optimizing performance both locally, and across a LAN and/or WAN. Specifically, there are two things we’re going to look at today. First, a way to… Continue reading Fast Summaries Re-revisited

If you do complex data analysis, then from time to time you probably need to group, summarize, and parse data into variables and/or fields.

And it was plenty fast, locally… and not too bad on a LAN… and technically,… Continue reading Fast Grid Displays on a WAN

We covered example 1 and most of the general concepts last time,… Continue reading FM 13: Virtual List Charts, part 2

FM 13: Virtual List Charts, part 1

Today we’re going to look at applying the virtual list technique to FileMaker charting with the goal of producing a reusable chart “object”, or rather, a series of chart objects. We’ll need more than one because while certain attributes (e.g., chart title) can be set programmatically, others, including type (e.g., column or line), must be… Continue reading FM 13: Virtual List Charts, part 1
