[Moose-dev] Re: Plotting time

For now on I’ve spotted 3 bottlenecks of plotting non-number values. 1) setMaxAndMinXValues self maxXValue: (self xValues max max: 0). self minXValue: (self xValues min min: 0) max: 0 and min: 0 are ruining things a bit. It will be nice to rethink this part. I’m not sure that it’s a good idea to have 0 all the time. Eg. I’d like to plot something in range 10100..10200 and as the result my data will take a very small place. Removing max: 0 and min: 0 solves the problem but they were put there for some reason. 2) getPixelsFromXValue: value ^ value * (self width) / (self maxXValue - self minXValue) We get problem when multiplying Date (value) by number. We can rewrite line in this way ^ (value - self minXValue) * (self width) / (self maxXValue - self minXValue) + minValue this way we operate with durations, which makes more sense. 3) sizeInPixelsOfPositiveXArea: maxSize "return the bar size (width or height) for the corresponding maxSize" (self minValue > 0 and: [ self maxValue > 0 ]) ifTrue: [ ^ maxSize ]. (self minValue <= 0 and: [ self maxValue > 0 ]) ifTrue: [ ^ maxSize * self maxXValue / (self maxXValue + (self minXValue abs)) ]. (self minValue <= 0 and: [ self maxValue <= 0 ]) ifTrue: [ ^ 0 ]. ^ self error: 'should not be here’ I have no idea what this does :). To make things work I just removed everything and made this thing return maxSize… So I’d really appreciate some kind of explanation. It will be good to push this into a working state. Cheers.
