Hi Evan, Roassal assumes to have 0 @ 0. However, you do a manual translation that works very well.

Roassal Axes

by Evan Donahue

Does anyone know how to change the min/max of the axes? I'm trying to figure out how to make x and y not start at 0. data := #(1000 1001 1002). b := RTGrapher new. ds := RTData new. ds points: data. ds x: [ :c | c ]. ds y: [ :c | c ]. b add: ds. b minX: 999. b maxX: 1003. b minY: 999. b maxY: 1003. b. ^ this does not do what I was expecting. If the data is all clustered together but far from zero, I'd like to adjust the axes so I can see the actual variation in the data, and not just a single point where everything is clustered. What is the right way to do this? Thanks, Evan

Re: [Pharo-users] How to select all changes in Epicea?

Hi Yann, I tried with your suggestion using ctrl+a and it selected all changes, although the selection background color is barely visible. It would be cool to have a menu item option.

My guy feeling is that some of the primitives used by FLLargeIdentityDicitonary become slower in latest VMs. I guess the main one to check is #fuelPointsTo: (primitive 132) (see the senders). Maybe you can do a quick test (isolated from your app) and compare agains old pharo ? Another thing would be comparing your scenario using a identity set. Just save your image before doing this: | set dict | set := FLLargeIdentitySet. dict := FLLargeIdentityDictionary. Smalltalk at: #FLLargeIdentitySet put: IdentitySet. Smalltalk at: #FLLargeIdentityDictionary put: IdentityDictionary. And re-run the serialization. Anyway, cannot think of much more things now. Cheers,

Well, hm, I have FLLargeIdentityDicitonary instances with up to 300'000 items... But that's what "large" means, right? Is there anything I can do here?

Thanks for this hint! I did that, and measured the same crazy difference, 6minutes vs. 1.5 minutes. So: It's not the storage! It's something inside Fuel. I keep investigating and will update here.

How to select all changes in Epicea?

by HernÃ¡n Morales Durand

Hi guys, My Pharo image crashed and I opened Epicea for the first time. I selected "Today" changes in the left pane and then after changes are displayed in the right pane, I expected a menu item, button or popup to select all code changes and then apply them. But I couldn't find the any option, even trying with holding key buttons and applying combination of clicks. What I am missing? Using Windows here. Cheers, HernÃ¡n
