visualization

问题 I am a newbie at Tableau (thought I have spent years working in R and Python), seems to be different in the way it handles things or I'm just not thinking the right way. I have a data sources with training data (employees training and the status). The point is to build a dashboard that shows the % of training that is overdue. I have all of the logic for it, but I am stuck on something. I have a calculated field to show me the total training due, then when I put that in a table, with a filter

问题 I have been having a strange error when visualizing some pages with a webview. I have found this problem when using a Samsung Tablet model SGH - I957 running Honeycomb 3.1 (On previous versions of android and other devices, I haven't seen this problem).

When pressing several times one of these inputfields, the page turns to black, leaving just the inputfield 'correctly' visualized. But when trying to

问题 digraph foo { a [label="<first> A | <rest> rest", shape=record]; b [label="<first> B | <rest> rest", shape=record]; a:rest -> b [label="foo", arrowtail=dot, dir=both]; } I would like to start the tail of the edge (a to b) from within a:rest (ideally in the center), is this possible? I am trying to draw linked lists using box and pointer like notation. 回答1: Yes, this is possible. The attribute to use is called tailclip: If true, the tail of an edge is clipped to the boundary of the tail node;

问题 I was asked to add shadows to a dashed-line in R. It would be similar to this image I found on-line, except it is for non-solid lines: I did not find any specific control/package for this purpose. If it was a solid line that I needed a shadow for, I would have simulated the shadow using another line with different opacity and thickness. But it seems for the non-solid lines (dashed, dotted, etc) this workaround won't work, since their gaps won't match as you change the thickness. Any ideas?

问题 I've got a JSON file that looks like this: { Object: { children: Array[4] ...

My problem is when I try to turn this into a set of nodes and links for use in a d3 force layout, I can't get it to display properly. I've tried using array.map or forEach to recursively

Suppose that I have the following string: "AUSTRALIA" INPUT : A OUTPUT : (A in red)'A'USTR(A in red)'A'LI(A in red)'A' 回答1: If you want to show it as text on axes (GUI), use the text command and Latex formatted strings text('string','{\color{red} A}ustralia') You can read about Latex commands here.
