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. There are various ways to accomplish this, including the Fast Summary technique, which regular readers of this blog may be familiar with, as it has made a number of appearances here… Continue reading Fast Summaries Revisited
Last time we looked at several summary reporting tricks, including a conditional subsummary (when an item’s Status is “Scheduled” it will have a value in the Substatus field — otherwise Substatus will be blank). The challenge was to generate a summary report showing Substatus only where appropriate, without seeing any annoying empty gray rows beneath… Continue reading Conditional Subsummary Report in Browse Mode
One of my favorite FileMaker functions is GetSummary; I use it frequently, and it had never occurred to me that there might be any alternative. Recently, however, Mikhail Edoshin pointed out on the FMPExperts list that GetLayoutObjectAttribute can serve as a viable replacement, like so:
Last October I began a series on Outer Joins, which explored a number of different ways to display summarized information in a grid, and at the time I concluded that the “fastest” method was to leverage the FileMaker relational model. And it was plenty fast, locally… and not too bad on a LAN… and technically,… Continue reading Fast Grid Displays on a WAN
Have you ever wished you could pull the values from a summary report, and use them in a script or a calculation? Back in the FileMaker 6 days, Mikhail Edoshin introduced a technique to do just that. He called the technique Fast Summaries, and I came to employ it extensively in my own solutions.
[10 June 2018: includes updated material from my recent dotFMP presentation.] [30 May 2018: check out my reassessment of the Fast Summary technique here.] Here are files that were demoed or referred to during my “Virtual List on Steroids” DIG-FM presentation on Thursday, May 10th, 2018 (VLR = “virtual list reporting).
Picking up where we left off in part 1, today we’re going to take a look at examples 2 through 6 in the Virtual List Charts demo file (the demo has been updated since part 1, so I recommend downloading a fresh copy). We covered example 1 and most of the general concepts last time,… Continue reading FM 13: Virtual List Charts, part 2
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
Last week we looked at building a FileMaker 11 native chart based on data that has been parsed into a field-based array. I happen to like field-based arrays, for reasons I’ll get to in a minute, but is a field-based array really necessary to generate the above chart?
