Spotfire 3D 绘图 [英] Spotfire 3D plot

问题描述

我使用调查绘制了一个 3D 井眼.我想根据某些裂缝深度为井眼的水平部分着色.我还有两个具有这些断裂深度的附加柱.有没有办法使用自定义表达式使用这两列为我的 3d 井筒着色，例如:if([measured.depth]>[upper.perf] and ([measured.depth]<[lower.perf]))，然后着色 Axis.measured.depth(蓝色).希望这是有道理的.谢谢

I plotted a 3D wellbore using surveys. I would like to color the horizontal sections of the wellbore based on certain fracture depths. I have two additional columns that have these fracture depths. Is there a way to use custom expression to color my 3d wellbore using these two columns, for example: if([measured.depth]>[upper.perf] and ([measured.depth]<[lower.perf])), then color Axis.measured.depth(blue). Hope that makes sense. Thank you

推荐答案

可能最直接和正确"的方法是创建一个新的计算列(插入»计算列).在这里，您可以构建一个稍后用于定义颜色的表达式.根据您提供的信息，该表达式可能如下所示:

probably the most straightforward and "correct" way to do this is to create a new Calculated Column (Insert » Calculated Column). here you can build an expression that will be used later to define colors. based on the info you provided, that expression could look like:

If([Measured Depth (ft)] > [Frac Lower Perf] AND [Measured Depth (ft)] < [Frac Upper Perf])

这将为 [Frac Upper Perf] 和 [Frac] 之外的值返回 True否则，降低性能] 和 False.您可以通过修改 If() 语句(有关详细信息，请参阅文档)使这些标签更具信息性(也许是内部"/外部"?)

this will return True for values outside of [Frac Upper Perf] and [Frac Lower Perf] and False otherwise. you can make these labels a bit more informational ("Inside"/"Outside" maybe?) by modifying the If() statement (see the documentation for details)

如果您打开可视化属性，然后转到颜色页面，您可以选择按列的颜色.选择我们刚刚创建的列.将颜色模式更改为唯一值并为真值和假值选择颜色.

if you open up the visualization properties, then go to the Colors page, you have options for the Color By Columns. choose the column we just created. change the Color Mode to Unique Values and choose your color for the true and false values.
