two improvements to how the X Axis is rendered: * The calculation for where a tick should exist has been improved. It now will ensure a tick is always at both the start of the axis and the end of the axis. This makes it clear exactly what data span is captured in the graph. * The second improvement is how the label on the last tick is written. It used to often get partially cut off, and with the change to ensure a tick is always at the end this could be seen more easily. Now the last tick has it's label written to the left so that it can be fully displayed. --- painter.go | 27 ++++++++++++++++++++------- 1 file changed, 20 insertions(+), 7 deletions(-) diff --git a/painter.go b/painter.go index 18496fd..450afdf 100644 --- a/painter.go +++ b/painter.go @@ -615,6 +615,17 @@ func (p *Painter) TextFit(body string, x, y, width int, textAligns ...string) ch return output } +func isTick(totalRange int, numTicks int, index int) bool { + step := float64(totalRange-1) / float64(numTicks-1) + for i := 0; i < numTicks; i++ { + value := float64(i) * step + if int(value + 0.5) == index { + return true + } + } + return false +} + func (p *Painter) Ticks(opt TicksOption) *Painter { if opt.Count <= 0 || opt.Length <= 0 { return p @@ -638,7 +649,7 @@ func (p *Painter) Ticks(opt TicksOption) *Painter { if index < first { continue } - if (index-first)%unit != 0 { + if ! isTick(len(values), unit, index) { continue } if isVertical { @@ -674,15 +685,13 @@ func (p *Painter) MultiText(opt MultiTextOption) *Painter { } count := len(opt.TextList) positionCenter := true - showIndex := opt.Unit / 2 + tickLimit := true if containsString([]string{ PositionLeft, PositionTop, }, opt.Position) { positionCenter = false count-- - // 非居中 - showIndex = 0 } width := p.Width() height := p.Height() @@ -690,6 +699,7 @@ func (p *Painter) MultiText(opt MultiTextOption) *Painter { isVertical := opt.Orient == OrientVertical if isVertical { values = autoDivide(height, count) + tickLimit = false } else { values = autoDivide(width, count) } @@ -699,7 +709,7 @@ func (p *Painter) MultiText(opt MultiTextOption) *Painter { if index < opt.First { continue } - if opt.Unit != 0 && (index-opt.First)%opt.Unit != showIndex { + if opt.Unit != 0 && tickLimit && ! isTick(len(opt.TextList)-opt.First, opt.Unit, index-opt.First) { continue } if isTextRotation { @@ -724,7 +734,11 @@ func (p *Painter) MultiText(opt MultiTextOption) *Painter { x = 0 } } else { - x = start - box.Width()>>1 + if index == len(opt.TextList) - 1 { + x = start - box.Width() + } else { + x = start - box.Width()>>1 + } } x += offset.Left y += offset.Top @@ -749,7 +763,6 @@ func (p *Painter) Grid(opt GridOption) *Painter { x1 := 0 y1 := 0 if isVertical { - x0 = v x1 = v y1 = height From 19173dfd37f737b4a5a681556b0a7fe661d749db Mon Sep 17 00:00:00 2001 From: Mike Jensen Date: Thu, 4 May 2023 17:59:11 -0600 Subject: [PATCH 52/73] painter.go: Optimize isTick function This reduces the loop frequency to one or two iterations in all cases.
