geotoolkit 测井曲线显示时间、深度双刻度

geotoolkit wellLog show two axis,depth anddepth

 

设置刻度道类型 md, tvd, time

new geotoolkit.welllog.widgets.WellLogWidget({
  'indexType':'md',
  'indexUnit':'ms'
})

 

添加刻度道，类型由widget 'indexType'决定

IndexTrack的单位由indexUnit决定，双刻度单位，需要自定义Header

wellLogWidget.addTrack(geotoolkit.welllog.widgets.TrackType.IndexTrack)

 

添加第二刻度道

geotoolkit.axis.Axis(tickGenerator)

logTrack.addChild(axis)

wellLogWidget.addTrack(geotoolkit.welllog.LogTrack)

 

createCustomHeader()自定义Header

其中若用LogAxis,将自动生成Header

var logTrack = new geotoolkit.welllog.LogTrack()



var times = [400, 1000, 2000, 4000];

var stepDepthMajor = 100;

var stepDepthMinor = stepDepthMajor / depths,stepDepthMajor,stepDepthMinor);

tickGenerator.setVisibleLabelGrade('MINOR',false)

tickGenerator.setVisibleTickGrade('MINOR',false)

var axis = new geotoolkit.axis.Axis(tickGenerator)



axis.setName("Depth")

logTrack.addChild(50)



var depthIndexTrackHeader = createCustomHeader(axis)

    .setBounds(new geotoolkit.util.Rect(logTrack.<span lang="EN-US" style="" font-size:"="">getBounds().getLeft(), 15, logTrack.getBounds().getRight(), 100))

// wellLogWidget.getHeaderContainer().addChild(depthIndexTrackHeader)

wellLogWidget.addChild(depthIndexTrackHeader)
